Answer:
Explanation as below.
Explanation:
As soil is composed of organic matter that includes the carbon contents, the fire regime leaves a bad impact on the soil nutrients such as bleaching of nutrients and minerals, also the crop fires are a common type of regime followed in various vegetation clearance practices. The dissolved soil organic content includes acids, fats, sugars, proteins, enzymes, and hydrocarbon fuels. As all organic matter consists of carbon , inorganic carbon is extracted from ores and minerals. DOC is abundant in minerals and freshwater. Also, forest fire on shrublands kills bacteria and fungi in soil surfaces. Loss of soil matter and increased bulk density can decrease the water keeping the holding capacity of the soil. Surface erosion by wind or gravity can also increase when ground cover.Why is the Far East considered as a land of contrasts and "untouched" resources? Explain.(please post at least 100 words)

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 22 1 pts Vertical mixing only occurs in which sphere? a) Stratosphere b) Troposphere c) Mesosphere d) Exosphere
Answer:
Vertical mixing only occurs in b) Troposphere
Explanation:
The troposphere is the sphere that is characterized by vertical mixing of air masses and air currents. As a result of the turbulence created in top layers of air. Here the uneven heating and cooling of land and oceans create convection currents to rise upwards and create up and downward movement of with environmental lapse rate and averages 6.5 ºC/km. This helps to push the troposphere boundary upward. The planetary boundary of motion creates such type of layer of air that moves through the poles and rising air stop at the tropopause as its the region or zone of mixing of air currents as all convective activity stops here.The space shuttle orbits at 248 km per hour above the earth how often do the astronauts see the sunrise in minutes

How do geologists determine where glaciers may have been in the past? What tools are required? What pieces of evidence are crucial to determine something like the existence of snowball earth?
Answer:
There exists continental ans valley glaciers who ages have determined on the basis of rock types and carbon datings
Explanation:
Glaciers were formed some 34 million years ago, in which first small glaciers were seen in Antarctica and that was 20 million years ago as the glaciers froze on to rocks and southern ice sheets were formed. The snowball earth existed from 2.4 to 2.1 billion years ago, at that time Huronian glaciation i.e oldest ice age was built on earth having unicellular mass. As in the earlier phase, the snowball was completely frozen and 250 million years after the big volcanic activity that spread the carbon dioxide into the atmosphere and created the greenhouse gases. Evidence can be taken from the quaternary period of glaciation some 2.58 million years ago. As the ice sheets have gone through the multiple periods of growth and retreat as in the interglacial period the ice melted and retreated. Roughly about 41,000 million years ago the tilting of axis of the earth had a major effect on the ice sheets around the globe.Why is the earth considered a dynamic planet? What are its three concentric layers and there properties?
Answer:
Yes, earth is a dynamic planet and the three concentric layer are core, mantel and crust.
Explanation:
Earth is a dynamic planet as it changes regularly, and this dynamism is a product of the earth rotation on its axis and a regular flow of energy from the internal to the external surface of the earth. Earth being formed about more than 4.5 billion years ago. The formation has created various layers of within the earth so dynamic that they need to be understood by modelling the earth. Earth is itself a form of geoid and is composed of rare earth and various other life-supporting elements that are not found on other planets to date. Earth's three concentric layers namely Core, Mantle, and Crust are all wrapped around layers of rocks that have transition layers separated by some discontinuity zones. The crust has a composition of lighter silicic rocks, composed of both continental and oceanic rocks of different ages, similarly, the mantel is composed of molten rocks that in their due course of time have solidified to form the upper and lower mantle. There thickness changes with varying depths. The core is made up of rock that has heavy metals like nickel and iron and also divided into the inner and outer core with varying densities of 9900 to 12,200.An ESP’s efficiency is increased from 96% to 98% total mass removal.

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.
In which of the below cases would winds be closest to geostrophic balance?
A. In meridional flow at the surface near the Equator.
B. At the surface in the eyewall of a hurricane.
C. In zonal flow at the surface near the Equator.
D. In zonal flow, just above the PBL, near 50°N
Answer:
C. In zonal flow at the surface near the Equator
Explanation:
As these winds have a problem with the Coriolis force that is the rotation of the earth on its axis. Occurring in mid-latitudes aloft the air currents. This balance does not occur near the surface since the friction force is significant. The geostrophic winds develop in a well-defined layer of air i.e either hot or cold. In a geostrophic flow of water bodies instead of the winds moving from high to low pressure, due to the rotation of the earth. The major current sin the ocean like Gulf stream and Kuroshio, and Agulhas current are all approximation and examples of geostrophic current.It is impossible to determine the "absolute" ages of sedimentary rocks because none of the grains in these rocks contain radioactive elements.

The stored form of glucose in the body is called
Answer:
Glycogen
Explanation:
Animals, including humans store this glucose fat in their cells, which are quickly available for energy. The excessive is stored in the liver, if you consume some extra carbohydrates the body stores the excess in the form of glucose. Mostly consisting of protein that comes from food about 300g per day. Human glucose is metabolized by glycolysis. The use of glucose in the cell in energy form is either by aerobic respiration, food sources of glucose can range from fruits, vegetables, and pulses. In plants, glucose is a product of photosynthesis also known as starch.The stored form of glucose in the body is called glycogen.
In animals including humans, glucose is primarily stored as glycogen. It is a polysaccharide made up of numerous glucose molecules connected by branches. In order to meet the body's energy needs during fasting or physical activity, the liver and muscles store glycogen. Glycogen undergoes glycogenolysis when blood glucose levels fall dissolving into individual glucose molecules to provide energy.
In contrast a process known as glycogenesis transforms extra glucose into glycogen during times of high blood sugar such as right after eating. This dynamic control of glycogen synthesis and breakdown keeps blood sugar levels stable and gives the body a ready source of energy.

The principle of constant proportions states that the elements in a pure chemical compound are always combined in the same proportion by mass. This principle applies to the salt in seawater, which is primarily Sodium Chloride, with a consistent proportion of Sodium and Chloride. It is also exemplified in the way certain salt-loving microorganisms thrive in constant salt conditions, and in the solubility equilibrium of salt in seawater.
Explanation:The principle of constant proportions, also known as the law of definite proportions, states that in a pure chemical compound, the elements are always combined in the same proportion by mass. This principle applies to seawater and its salt content. Salt in seawater is primarily Sodium Chloride (NaCl). Regardless of the location, the proportion of Sodium and Chloride in Sea Salt is always nearly constant, approximately 39.34% Sodium and 60.66% Chloride by mass.
For example, the principle is evident in the way certain microorganisms called halophiles ("salt-loving") thrive in marine environments where salt concentrations hover at 3.5%. Extreme halophilic organisms, like the red alga Dunaliella salina and the archaeal species Halobacterium, can even survive in hypersaline lakes such as the Great Salt Lake or the Dead Sea, which are several times saltier than the ocean.
Another facet of this principle can be seen in how solubility products work. The solubility of a substance, such as salt in seawater, can vary from essentially zero to infinity, producing saturated solutions when the solubility limit is exceeded. The equilibrium between the dissolved and undissolved salt is also part of this principle of constant proportions.

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.

Subducting forces played a crucial role in formation of the islands.
Explanation:
These are known as the formation of Archipelago. Many thousands of islands that constitute the philippine island are an Icelandic arc and volcanic in origin. That is supposed to have been formed after the subduction of plates that collided together such as the Eurasian plate, Philippine Sea, and the Indo Australian plate. Being made up of 7,000 island groups. countries situated around the pacific ring of fire. Consist of 11 small islands while the rest are large islands that cover 90% of the surface area of the philippine plate and Luzon alone covers about 40,541 square miles. The original Icelandic arcs are known to have been colloidal earlier with the Sundaland forming a series of Archipelago. Melting of molten lava in the earth's crust leads to the formation of a series of chains that are seen today as the philippine islands.EXPLAIN HOW METAMORPHISM CAN ALTER A ROCK CHEMICALLY AS OPPOSED
TO MINEROLOGICALLLY.
Answer:
The rocks are comprised of cracks and fractures in between the sediments and mineral grains that have the capacity to store fluid in them. This fluid is generally the water that contains various types of dissolved ions. These fluids in the rocks are very much important because the chemical reactions that take place include the change in mineral from one type to another new type. This can highly increase the amount of dissolved ions that are dissolved and transported by the water. This alteration of rock that occurs chemically due to these fluid refers to the process which is commonly known as the metasomatism. Whereas, the rock alters mineralogically due to the increasing temperature and pressure condition, that changes the grade of rocks.
This is how metamorphism alters the rock chemically in comparison to mineralogically.

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.
Consider a sample of water from a stream found to have an initial DO of 10.0 mg/L. It is placed directly into a BOD bottle and incubated for 5 days at 20C. After 5 days, the DO is found to be 5.0 mg/L. What is the BOD5 for this sample (mg/L)?
Answer:
The BOD5 for this sample is 5 mg/L
Explanation:
The BOD5 takes into consideration the difference between the initial DO and the final DO divided by the fraction of the sample tested in a 300 mL BOD flask. The problem states that the sample was directly placed in a BOD bottle so we assume that the volume used was 300 mL of the water sample. The fraction of water is 1 (300/300).

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.

why can't high quality energy resources such as oil be recycled?
Answer:
Oil is one of the most efficient and widely used energy resources. These are fossil fuels. When the ancient plant and organisms dies they accumulates at the bottom of the seas, which are then covered by the sediments such as mud and sands, forming various rock layers. These trapped organisms an plants after millions of years turn into fossils, by undergoing the fossilization process. These are non-renewable energy resources or conventional sources of energy. In addition to oil, coal, petroleum and natural gas are also some examples of non-renewable energy.
Thus, the high quality resources or energy such as oil, petroleum and natural gas cannot be recycled.
