Answer:
B) stay the same
Explanation:
The stars set to rise and fall daily from the sphere of the equator and instead viewed from the poles. In the northern hemisphere, the stars go the full circle. Around the north celestial poles precisely once a day. At 0 degree the star named Polaris is seen and will the same when viewed from all angles. Thus there appears to be more stars at the equator and hence, stars move parallel to the celestial equator.Answer: Stay the Same

3. What happens and what results from an Earth's precession?
Answer:
Explanation:
The earth rotates on its own axis. When the rotational axis of the earth changes, it leads to precession. Earth's precession is a common phenomenon that has been observed by astronomers for a long time. The effect of changing axis of rotation would be the amount of solar radiation that would be received at any point on the earth.
QUESTION 6 When a plate of oceanic lithosphere meets a plate whose leading edge is continental lithosphere along a convergent plate boundary, what is the result? A volcanic island arc, like the modern Aleutian Islands in Alaska. A mountain belt, like the modern Himalayas. Earthquakes, but no volcanism, like the modern San Andreas Fault in California. A continental volcanic arc, like the modern Andes. QUESTION 7 10 The magnetic field of Earth in the geologic past is Click Save and Submit to save and submit. Click Save AllA to save all answers
Answer:
1- Option (4)
Explanation:
When two plates, namely the continental and oceanic plate strike one another, then the denser oceanic plate gets subducted below the less dense continental plate. Due to this subduction zone is formed marked by the deep-sea trenches. The subducting plate undergoes partial melting due and the magma eventually rises up towards the surface of the over-riding plate, forming the continental volcanic arcs. For example, the San Andes mountain which is formed due to the collision between the North American and the Pacific plate.
The earth's core is comprised of denser, molten and hard rocks, that constantly move due to the earth's rotation. As a result of this, the continuous motion of liquid iron initiates electric currents, which again, in turn, produces the earth's magnetic fields. The rotational speed of the earth is directly proportional to the strength of the magnetic field.
According to the geological evidence, there occurred about 170 magnetic reversals in the past 75-80 million years. In the preceding Matumaya Magnetic Chron, the North Magnetic Pole was oriented towards the Northern Hemisphere.
At present, the strength of the magnetic field of earth is weakening by about 5%. If it continues at this rate then, it may reach zero within some thousands of years.
At a convergent boundary where oceanic lithosphere meets continental lithosphere, a continental volcanic arc is formed, such as the Andes. This is due to the subduction of the oceanic plate beneath the continental plate, creating magma that forms volcanoes.
Explanation:When a plate of oceanic lithosphere meets a plate whose leading edge is continental lithosphere along a convergent plate boundary, the result is the formation of a continental volcanic arc, similar to the modern Andes in South America. This occurs because the denser oceanic plate subducts beneath the continental plate, leading to melting of the subducted crust and the creation of magma. This magma rises to the surface to form volcanoes along the continental margin. Examples of continental volcanic arcs include the Cascade Range of the Pacific Northwest in addition to the Andes Mountains.

An Fm radio station broadcasts at 85 megahertz(MHz) What is the energy of each photon in Joule? Use h=6.6 x 10 to the 34th Js for the Planckconstant
Final answer:
Each photon from an FM radio station broadcasting at 85 MHz has an energy of approximately 5.61 × 10^-26 joules, calculated using Planck's constant and the frequency of the photon.
Explanation:
To find the energy of a photon in joules from an FM radio station broadcasting at 85 MHz, we can use the equation E = hf, where h is Planck's constant and f is the frequency of the photon. Planck's constant (h) is given as 6.6 × 10-34 joule seconds (Js), and the frequency (f) is 85 MHz, which is 85 × 106 hertz (Hz).
In this case, the energy (E) of each photon can be calculated as follows:
E = (6.6 × 10-34 Js) × (85 × 106 Hz)
E = 5.61 × 10-26 joules
Thus, each photon from an FM radio station broadcasting at 85 MHz has an energy of approximately 5.61 × 10-26 joules.
You probably believe that the earth is spherical, but it is obvious that the earth is flat. Look around; where do you see the curvature? One classmate suggests that if you call someone on the "other side" of the world by phone, he or she will answer and, for instance, it will be midnight there at the instant it is noon here. Another student reminds you of the picture taken of the spherical earth from the moon landing. Your teacher explains the ancient observation that when the sun was directly overhead on one day near the equator, a pole some hundreds of miles away to the north still cast a shadow. What is the best scientific basis for still considering that the earth is spherical?

the planets are all spheres.
Explanation:
the planets are all spheres. even the sun is and it's a star .
The ratio of brightness of two stars can be determined by a
constant of 2.512 raised to the power of the magnitude difference.
The formula is b1/b2=2.512(m2-m1) where b1 and b2
represent the brightness and m1 and m2 refer to the magnitudes of
the stars being compared. One star has a magnitude (m1) of 1.6, and
another star has a magnitude (m2) of 0.4. What is the ratio of
brightness of these two stars?
Answer: 0.33
Explanation:
The ratio of brightness of two stars is given by:
[tex]\frac{b_1}{b_2}=2.512^{(m_{2}-m_{1})}[/tex]
Where:
[tex]b_1[/tex] is the brightness of star 1
[tex]b_2[/tex] is the brightness of star 2
[tex]m_{1}=1.6[/tex] is the magnitude of star 1
[tex]m_{2}=0.4[/tex] is the magnitude of star 2
[tex]\frac{b_1}{b_2}=2.512^{(0.4-1.6)}[/tex]
[tex]\frac{b_1}{b_2}=2.512^{(-1.2)}[/tex]
Finally:
[tex]\frac{b_1}{b_2}=0.33[/tex] This is the ratio of brightness
1) A fold-thrust belt is associated with
Subduction
Continental Rifting
Oceanic Rifting
A transform fault

a. Colorado Plateau.
b. Transition Zone.
c. Southern Rocky Mountains.
d. Southern Basin and Range and Río Grande Rift.
Answer:
a. Colorado Plateau
Explanation:
It is home to a population of 2.1 million, who live in this region, the climate of this place is considered as semi-arid and total precipitation of 250 mm. Since prehistoric times this place is home to the little ice age settlers of 18 century. Similarly, other human activities such as grazing and livestock raising and the country have a good deer population. There has been a 13.24% increase in population since 2010, and the country capital Denver is estimated to be more than 35 lakh people. 81% white people, 20.7% Latin American and others 4% black people. Colorado has large African American communities and neighboring areas. The majority of the religion is Christian about 64%, 44% protestant, and 16% roman and 3% catholic. The economy is mostly dependent on agriculture.Question 3 Multiple Choice Worth 1 points) Which of the following rangeland management practices would most likely result in a tragedy of the commons? Constructing electric fences around open plots of land Eliminating government restrictions on public grazing of cattle Punishing ranchers whose cattle overgraze public rangelands Requiring ranchers to graze their cattle in different pastures throughout the year Selling publicly accessible rangelands to private individuals
Eliminating government restrictions on public grazing of cattle most likely leads to a tragedy of the commons, where unrestricted actions by individuals deplete shared resources.
Explanation:The tragedy of the commons is a situation in which individuals acting in their own self-interest can deplete shared resources, leading to long-term collective negative outcomes. Given the options provided, eliminating government restrictions on public grazing of cattle would most likely result in a tragedy of the commons. This is because without restrictions, each rancher may attempt to maximize their benefit by adding more cattle to the commons, leading to overgrazing and depletion of the resources.
With what is foliation most associated with?
A. evaporites
B. micaceous minerals
C. metamorphic rocks
D. shear zones
subduction zone
Answer:
C. metamorphic rock
Explanation:
As foliation in geology refers to the repetitive wearing of metamorphic, each layer s thin as a sheet of paper rocks caused due to the shearing forces in different sections of rocks. Usually occurs in mudrocks, slate, schist, and gneiss. They are oriented to small flakes of clay in slates. Usually y the impact of some physical forces affecting the growth of rocks. Often foliation is lined to diagenetic metamorphism. Igneous rocks get foliated by the crystals in convection by the larger magma chambers due to ultramafic intrusions. Foliation this in general sense ends to curve around ridges such as those of granites having often fine observations on outcrops.What is the likely composition of Pluto?

1. The discoveries frequently arrives in a language that may be inconceivable to the greater part of the open strategy creators.
2. Connecting the activity/learning hole requires enormous changes of the interfacing components among arrangement and science or rather among science and society all in all.
3. There is an enormous requirement for an extraordinary number of individuals who make science strategies, who reserve science and furthermore do the examination work and discoveries.
What would happen to shipping companies if the Gulf Stream stopped?
Answer:
Explanation:
The Gulf Stream can be define as the stream of water originates in the gulf of mexico and stretches to the Florida. It consists of warm water. It provides the protective warm shield of water over the Europe.
If the Gulf stream stopped the environment of the colder polar region will become more severe. This will result in crash of marine diversity along the US east coast. This can result in destruction of the food chains, situations of starvation for population depending upon fish food, and misery.
If light travels 1% times faster in air than in water, what is the n of water? Show your work.
Answer:
n=1,0101
Explanation:
considering n as the refractive index, then you can assume that the decrease of the speed, is because of the density of the medium where it's travelling, so we can translate this as :
[tex]n=\frac{c}{v}[/tex]
if your initial speed is C=100%V , then if it's decrease 1%, you have that V=99%.V (final Velocity)
[tex]n=\frac{c}{v}[/tex][tex]n=\frac{100V}{99V}[/tex][tex]n=\frac{100}{99}[/tex][tex]n=1,0101[/tex]I hope it helps you..

Why has only one hurricane
been observed in the South Atlantic Ocean, whereas the North
Atlantic Ocean has had hundreds in the past century?
Answer:
Rotation of earth that moves the winds from the north to right side and left in southern side.
Explanation:
The south Atlantic ocean has fewer weather phenomena and other disturbing events after the extremely rare hurricane of 2004 Hurricane Katrina, as most of thee occur in November and others mostly occurring in cold months. Whereas north Atlantic is home to various tropical as well temperature disturbances. As most of the conditions needed to form the cyclones and hurricane are present in the northern sphere were they can grow and develop. ITCZ surrounding the equator has strong winds that push and deflect the winds as wind shear doesn't occur in these zones.Why is the Far East considered as a land of contrasts and "untouched" resources?

Far east land is a land of the rising sun the Japanese coast and along with the eastern Siberia and Indonesian islands these lands belong to the variety of biodiverse resources in the world. Plus they have long traced the history of natural resources and abundance and most of these are untraced or undiscovered by man. For example the marina trench its proper depth still unknown to man. Parts of Russia and China and other nearby states have an untouched resource found in underwater reserves that harbor exotic species and possible changes of fresh marine life forms making far east as most of the valuable resource on earth.describe different types of volcanoes, how do they form? can volcanoes change the climate if so how? can volcanic eruptions be predicted why?
Answer:
There are mainly 4 types of volcanoes.
Explanation:
1. Cinder cones: They are a bowl-shaped crater, build from particle or blobs of congealed lava that is ejected from a single gas vent, as the air is broken into small fragments that are solidified and falls as cinders.
2. Composite volcanoes: stratovolcano or composite cone are those that form a steep-sided, symmetrical cone of large dimensions built around by lavas. Some examples are Mount Shasta in California, Mount Hood in Oregon.
3. Lava domes: There internal structure is defined by bulbous masses of lava, that are too vicious.
4. Shield volcanoes: These are built entirely by fluid lava, and flow p[ours in all directions.
A volcano can change its surrounding weather patterns but not the climate of a place as a climatic zone is composed of stable and static atmosphere like that of poles, tropics, and temperate lands, etc.
Not all volcanic eruptions can be predicted successfully as they are also triggered by an earthquake and the active or dominant type of volcano can be identified based on its previous eruption patterns.
Which of the Jovian planets experiences a dramatic seasonal change?
a. Jupiter
b. Saturn
c. Uranus
d. Neptune
Answer:
A. Jupiter.
Explanation:
As Jupiter has the largest planetary atmosphere its lacks a clear boundary and gradually transitions to the liquid interior of the planet. Having their temperature gradient. The jovian atmosphere has a large range of active phenomena including the band instabilities and anticyclones, and cyclones and storms and lightning. These cyclones are large red, or brown such as the Great red spot of Jupiter. Hence, Jupiter has the most powerful type of storms being accompanied by the convection in the atmosphere as the striking of lightning from the clouds in 10 times more stronger than on earth. Jupiter also consists of upper clouds, located in the low-pressure range are made of ammonia ice. Auroras are a permanent feature of the Jupiter's atmosphere based on the exiting models temperature predictions of the atmosphere are no higher than 400k. Strong jets have been observed at the equator of the by the deep models. Temperature and winds are found to rise from the equator to the poles, thus confined within zones. As a comparison to the anticyclones, the jovian cyclones tend to be small dark and irregular.1. Which of the following explains why Earth has seasons?
A. The Earth moves slightly closer towards and further away from the Sun throughout the year
B. The Earth is tilted relative to the ecliptic
C. The Earth is mostly covered in water
Answer:
B. The Earth is tilted relative to the ecliptic
Explanation:
Its due to the earth has an axial tilt of 23.5 degrees which is an inclined motion, relative to the orbital plane of rotation. This is the angle of obliquity of the earth from its center. For this reason, the earth has solstice in summer, winter, vernal and equinoxes and owning to the fact that the continents in the north have winter in the Northern hemisphere and continents in the south have summer. Without this tilt, the earth would have climatic extremes. Day and night time of the earth are also influenced by the same rotational motion.Question 6(Multiple Choice Worth 3 points) B If solidification ages at the Mid-Atlantic Ridge are around 10,000 years old, what does this tell you about the Mid-Atlantic Ridge? The Mid-Atlantic Ridge began to produce oceanic crust 10,000 years ago. The youngest rocks in the Mid-Atlantic Ridge solidified 10,000 years ago. The Mid-Atlantic Ridge ceased producing oceanic crust 10,000 years ago. The rocks at the Mid-Atlantic Ridge recorded the magnetic fields 10,000 years ago. The rocks adjacent to the Mid-Atlantic Ridge are older than those further away from the ridge.
Answer:
Option (2)
Explanation:
The mid oceanic ridge is the region along which two plates moves away from one another. This occurs in the divergent plate boundary. The magma, during this type of plate motion, comes out to the surface of the ocean floor and solidifies immediately due to the lowering temperature, giving rise to the formation of basaltic rocks.
The solidification age refers to the time when the magma last crystallized as it ejected at the ocean floor.
According to the given condition, the magma last solidified nearly 10,000 years back in the mid oceanic ridge, which are considered to be the youngest rocks found along the mid oceanic ridge.
Thus, the correct answer is option (2).
A particle called the pi-meson is made from an up quark and an antidown quark. What is the charge of this particle?
The pi-meson, composed of an up quark and an antidown quark, carries an overall electric charge of +1 because the charges of its constituent quarks sum to +1.
Explanation:A pi-meson is composed of an up quark and an antidown quark. Quarks are subatomic particles that each carry a fractional electric charge. Specifically, an up quark carries a charge of +2/3, while an antidown quark - being the antiparticle of a down quark - carries a charge of +1/3.
The total charge of a particle is the sum of the charges of its constituent parts. Therefore, to find the charge of the pi-meson, simply add together the charges of the up quark and the antidown quark.
In the case of the pi-meson (up quark, antidown quark), the total charge is (+2/3) + (+1/3) = +1. Thus, a pi-meson has an electric charge of +1.

Question 15(Multiple Choice Worth 3 points) W Which of the following is not commonly associated with a plate boundary? fault hot spot O mid-ocean ridge O mountain trench
Answer:
Option (1)
Explanation:
Hotspots are the regions where the magma rises towards the surface due to the presence of large mantle plumes. The force exerted by the magma here is very high. When the lithospheric plates move over these regions, the magma comes out to the surface forming volcanoes. And as the plates move away from the region of hotspot they eventually cool. These hots spots are fixed at a place. There are numerous hotspots on earth. for example, the Hawaiin island chain, below which there are regions of hotspots.
Thus, the hotspot regions are not associated with the plate boundaries.
Hence, the correct answer is option (1).
Part A When should sketches be made instead of just recording data? Select all that apply. When the amount of recorded data would exceed the length of two written pages. U When unusual conditions need to be shown for later reference. When recording the work performed. Anytime there is a major time constraint. 0 Anytime observations need to be clarified
Final answer:
Sketches are useful when recording unusual conditions, under time constraints, when clarifying observations, or when excessive data preclude lengthy written descriptions. In field research, sketches can help document environmental details and changes. Practice improves sketching ability, which is an essential skill for capturing important information quickly.
Explanation:
Sketches should be made in several instances to support recorded data: when unusual conditions need to be visually communicated for later reference, when there's a major time constraint and quick visual representation is more efficient than lengthy descriptions, and whenever observations need to be clarified for better understanding. Sketching can be more effective than writing when the amount of data to record is excessive, such as when it would exceed the length of two written pages. Additionally, sketches are beneficial for recording the layout of the land in field research, documenting changes over time (e.g., before and after pictures in scientific work), and supplementing field notes that cannot be captured in written form alone, such as details of a site's color, shape, size, texture, and arrangement. While in the field, taking precise notes is crucial, but they should be accompanied by sketches or visual records that can provide a richer context and aid in recall and analysis. It is encouraged to practice sketching, as over time it will improve the ability to quickly capture important information visually.
Furthermore, while capturing field observations, it's also essential to detail the surrounding environment and interactions, which can be supported by maps, photographs, or recordings. Making sketches should not be hindered by a lack of artistic skill - the goal is to record what is deemed important swiftly.
Which of the following statements is true?
1.The Middle Ages cover a period included between the end of the Roman Empire and Renaissance (Modern Age)
2.The Middle Ages cover a period included between the beginning of the Byzantine Empire and the Renaissance (Modern Age)
3.The Middle Ages cover a period included between the Romanesque style and the Gothic style
4.The Middle Ages cover a period included between the fall of the Babylonian Empire and the beginning of the Roman Empire
Statements 1 and 3
b.
Statement 1 only
c.
None of these statements are true
d.
All statements are true
Answer:
b) Statement 1 only
Explanation:
The right answer is: b) The Middle Ages cover a period included between the end of the Roman Empire and Renaissance (Modern Age).
The Middle Ages is a historic period that happened during the 5th to 15th centuries. The event that marks its beginning is the fall of the Western Roman Empire.
As all periods of history, the Middle Ages is a consequence to the period before it. Once the Roman Empire fell, power was decentralized and kingdoms emerged all over Europe. This period is also called the "dark ages" because there was a big shift in cultural development influenced by power and religion.
The Middle Ages are divided in three sub-periods: Early Middle Ages, High Middle Ages and Late Middle Ages. During the Late Middle Ages, life began to change again: wars, famine and pandemics stroke, and intellectuals started reacting against the religion impositions. This is how Renaissance emerged.
Renaissance means "reborn", this name represents how mankind turned back to humanism. After centuries of "being in the dark"; classical Greek and Roman philosophy was "reborn". This period was a natural predecesor to the "age of reason", the Enlightenment.
Final answer:
The statement that is true regarding the Middle Ages is that it covers the period between the end of the Roman Empire and the Renaissance, making statement 1 the only correct choice. The Middle Ages spanned from the 5th to the 15th centuries, being a significant period of transition in Western history.
Explanation:
Which of the following statements is true regarding the period the Middle Ages covers? The correct answer is Statement 1 only, which states that the Middle Ages cover a period included between the end of the Roman Empire and the Renaissance (Modern Age). The Middle Ages, or Medieval period, spanned from the 5th until the 15th centuries, initiating with the collapse of the Western Roman Empire and concluded by the onset of the Renaissance and the Age of Discovery. This era is recognized as the middle period in the traditional division of Western history into Classical, Medieval, and Modern periods.
Historically, this timeframe is divided into the Early Middle Ages, the High Middle Ages, and the Late Middle Ages, showing a complex societal transition towards what was later identified by the Renaissance scholars as a reawakening of classical learning and cultural achievements. Therefore, other statements which incorrectly bound the Middle Ages either with architectural styles (Romanesque and Gothic) or incorrect historical periods (the Byzantine Empire's beginning, the fall of the Babylonian Empire) do not accurately describe the true chronological span of the Middle Ages.
Will day lenght change faster near the equinox or near the
solstices?
Answer:
Daylight will change more faster near the equinox
Explanation:
As the sun motion from north to south is greatest the daily changes in daylight occur is the greatest As near the poles the sunlight can remain from 6 to 18 hours. Days end to stay longer as the duration of the summer solstice, based on the tilt of the earth around the sun. More time is taken to move around the southern hemisphere in winter as compared to the Northern hemisphere in summer. The sun quickly covers large areas of the earth a the time of equinox as compared to that of the solstice. Similarly, the cycle of seasons changes as solstices have maximum and minimum delineation toward the angle of the sun.The length of a day changes faster near the solstices when the Sun reaches its highest or lowest point in the sky.
Explanation:The length of a day changes faster near the solstices. At the solstices, the Sun reaches its highest or lowest point in the sky, resulting in the longest or shortest day of the year, respectively. As the Earth moves through its orbit, the rate at which the length of day changes is most pronounced near these points. During the equinoxes, the day and night are approximately equal in length.
Why is the Centrifugal Force excluded from the full Equations of Motion?
A. It is the result of an imbalance of forces already included in the equation.
B. Its inclusion leads to imaginary numbers as a result.
C. It applied only to the Northern Hemisphere.
D. It has a value of zero in this frame of reference.
Answer:
Centrifugal force is a force caused due to the inertia of the earth, its directed away from the centre from the axis passing through the coordinates of the rotation. Thus is a result of an imbalance of forces already included in the equation
Explanation:
As it's not a real force its due to the tendency of the objects of the circular path to leave the path in a straight line. As finally, the tangent velocity remains constant hence the path perpendicular to object running from the center. For an equation of motion, uniform acceleration has to be taken place, is described in terms of displacement and velocity the instead the centripetal force keeps the object together, as the centripetal force is guided by gravity and two-body problems apply to the spinning of less angular speeds.
