Answer:
Mid-Atlantic Ridge
Explanation:
It's here that the two oceanic crust split up an leads to the rising of magma or lava from the seafloor and thus this is called a divergent boundary and it leads to the creation of a new crust a new layer of rocks at the strata. Mid Atlantic ridges are existing since the creation of the earth and are a fundamental aspect of the formation of the plats on the surface of the earth. The upwelling of lava from the volcanic eruptions and earthquakes is result of the mantle plumes produced due to the this divergent boundary. Mid Atlantic ridges, thus account for the entire chain of the earth's surface features like mountain ridges, trenches, and deep-sea bottoms. Source of the convergence and other faults.Two tectonic plates are diverging along a Mid-Oceanic Ridge. Which of the following features would NOT be found along that type of plate boundary?
a. Shallow earthquakes
b. Strong, deep earthquakes
c. Rifting and Normal Faulting
d. Symmetrical "stripes" of positive and negative magnetism parallel to the ridge
e. New crust being created directly from the mantle
f. Transform boundaries perpendicular to the ridge
g. Fissure volcanoes
Answer:
In a Mid-Ocean Ridge we are not going to find Strong, deep earthquakes
Explanation:
A Mid-Ocean Ridge is produced by divergence between plates, what generates a rift zone with normal faults; this kind of faluts are the result of tensional stress, that makes blocks to fall. When blocks are falling, they can produce some shallow earthquakes.
As plates are separating, there is growing a space between them and this allows magma to arrive to the surface, creating fissure volcanoes that are being part of the new crust that is being created. When rocks get cold, their magnetic minerals get oriented to the magnetic north, for that reason, as magma (next rocks) is being desposited at both sides of the ridge, we can find symmetrical stripes of positive and negative magnetism parallel to the ridge.
When ridges break up because of stress differences in the different segmentes, transform boundaries appear to conect all the ridge. On transform boundaries the displacement is horizontal, for that reason the are perpendicular to the divergent boundaries.
The Strong and deep earthquakes are not going to find under Mid-Ocean Ridge.
What is a Mid-Oceanic Ridge?A mid-ocean ridge refers to a seafloor mountain system which is constituted by plate tectonics.
It has an extent of about 2,600 meters and arises about 2,000 meters preceding the deepest percentage of an ocean basin. This dimension is where seafloor dispersive takes place along a different plate boundary.
It is created by separation between plates, which creates an opening zone with average faults. This kind of faults are the outcome of tension stress, that makes blocks to fall. They can produce some shallow earthquakes, when blocks are gone down,
There is growing a space between them and this allows magma to arrive to the surface, As plates are separating. And creates fissure volcanoes that are being portion of the new layer that is being created.
When rocks get cold, we find symmetrical stripes of positive and negative attraction parallel to the ridge and New crust being created directly from the mantle.
Therefore, option A is correct.

What is the relationship between heat production and resistance as related to electricity?
Answer:
Heat produced is directly proportional to resistance
Explanation:
Heat produced is directly related to the resistance if resistance will be more then heat production will also be more
The heat in produced is given by [tex]H=i^2RT[/tex], here i is current, Ris resistance and T is temperature.
From the relation we can see that heat is directly proportional to resistance so if we increase the resistance then heat produced also increase and if decrease the resistance heat produced decreases.
What is meant by the half-life of an unstable element?
Answer:
Half-life is defined as the time required by an unstable element to reduce half of its original value. All unstable elements have a decay rate and this half-life differs from element to element. These unstable elements are known as radioactive elements. It continuously decays until it becomes a stable one. These elements when decays release radiations which are harmful to lives.
This half-life plays an important role in the determination of the age of a rock or fossils. It is used in various types of radiometric dating methods.
For example, the half-life of Carbon-14 is approximately 5700 years and the half-life of Uranium-238 is 4.5 billion years.

Does weathering of carbonates produce the same effect on atmospheric CO2as weathering of silicates? Explain your answer.
Answer:
Explained
Explanation:
The weathering of carbonate rocks or minerals, produce different acids as well as water. Some acids are hydrochloric acid, carbonic acid also bicarbonate. Again they break down from the element to produce CO2 into the atmosphere.
The main source for the generation of atmospheric CO2 is from the carbonates on the earth. But weathering of silicate does not liberate much CO2 than carbonate. The carbonation is more effective in weathering than silicate. Most of alkali metal like sodium, potassium, calcium and magnesium undergo the process of carbonation. Silicate minerals contribution to atmospheric CO2 is very less.

A common radio wavelength observed coming from astronomical objects is 21 cm. what temperature is associated with this radiation? 1st attempt See Hint Feedback 13.8
Final answer:
The 21 cm line in radio astronomy is significant for studying hydrogen in space; it has a wavenumber of about 4.76 m-1, an ordinary frequency of approximately 1.43 GHz, and an angular frequency around 8.98 × 10^9 rad/s. Long wavelengths are often emitted by cold, extended objects such as gas clouds, whereas short wavelengths are indicative of hot, energetic environments.
Explanation:
The 21 cm line is an important radio wave in radio astronomy, originating from the transition between the hyperfine levels of the ground state in neutral hydrogen. This specific wavelength allows astronomers to measure the galaxy's structure and motion. To calculate the wavenumber, you divide 1 by the wavelength in meters, which for 21 cm (0.21 m) gives us a wavenumber of approximately 4.76 m-1.
To find the ordinary frequency, you divide the speed of light by the wavelength in meters: frequency = c / λ = (3 × [tex]10^{8}[/tex]m/s) / (0.21 m) ≈ 1.43 GHz. The angular frequency is given by 2π times the ordinary frequency, which is about 8.98 × 109 rad/s.
Objects emitting radiation at very long wavelengths, like the 21 cm line, are typically large, cold structures such as gas clouds, while short wavelength radiation can be associated with very hot, energetic events like supernovae or accretion disks around black holes.

3. Which of the following only happens within the arctic or antarctic circle?
A. The Sun reaches the zenith
B. The Sun rises in the west and sets in the east
C. The Sun does not cross the meridian
D. The Sun is up for 24 hours at a time
Answer:
C. The Sun does not cross the meridian, which is an imaginary line.
Explanation:
As all Meridien converges at the north and south poles, as there are no longitude or meridian lines running at this place so the sun continues to remain suspended at the same place throughout the day. As the solar noon is at other places on the earth and not at the poles of arctic and antarctic. Thus the sun does not go up or down this meridian. Rather its altitude in the sky constantly increases in winters, and sping and decreases in summers. All of this takes place due to the rotation of the planet on its axis. The tilt in motion creates an inclination for the sun rays falling on earth.Final answer:
The correct answer is D. The Sun is up for 24 hours at a time.
Explanation:
The Arctic and Antarctic Circles are significant because within these regions, polar day and polar night phenomena occur. Specifically, north of the Arctic Circle and south of the Antarctic Circle, the sun does not set for a full 24-hour period around the time of the summer solstice, resulting in what is called the "midnight sun". Conversely, during the winter solstice, these regions experience a 24-hour period without sunlight, known as the "polar night". This phenomenon does not occur anywhere outside of the polar circles. The sun never reaches the zenith, which only occurs up to 23.5 degrees from the equator (in the Tropics), and it never rises in the west and sets in the east nor does it fail to cross the meridian in a regular diurnal cycle outside of these unique polar day or night conditions.
Question 2(Multiple Choice Worth 3 points) Which of the following is most dense? asthenosphere continental crust core O mantle oceanic crust
Answer:
Mantle oceanic crust
Explanation:
The Asthenosphere consists of heavier elements like aluminum, magnesium basaltic rocks and made up of old oceanic plates. This liquid layer is based on deformation properties. Which are later characterized by Isostatic adjustment? Due to high temperature and pressure conditions in this layer the rock is in the molten state. Plates above move in n ductile manner as the oceanic crust has a density of 3.0 g/cm cube, and that of continental crust is about 2.83 g/cm cube. Thus lighter plates or continents can move on this layer as they are less dense and hence they, later on, move back into the same oceanic trenches through the process of subduction.Which of the following radiations has the shortest wavelength?

Question 5: For a planet in an elliptical orbit to "sweep out equal areas in equal amounts of it", it must... a) move slowest when near the Sun. b) move fastest when near the Sun. c) move at the same speed at all times. d) have a perfectly circular orbit.
Answer:
Option (B)
Explanation:
According to the Kepler's 2nd law regarding the planetary motion, as the planets moves in an elliptical path, orbiting around the sun, and the line joining both the sun and planet forms an equal amount of area in equal amount of time. This equal area in equal time is maintained by the faster speed of the planet near the sun (Perihelion) and slower speed of the planet at a distance away from the sun (Aphelion).
Thus, the correct answer is option (B).
The correct answer is (b) the planet must move fastest when it is near the Sun, as described by Kepler's equal-area law, which is part of his laws of planetary motion.
For a planet in an elliptical orbit to "sweep out equal areas in equal amounts of time," it must move fastest when near the Sun. This is known as Kepler's equal-area law, which is one of the laws that describe planetary motion. According to this law, the line connecting a planet to the Sun sweeps out equal areas during equal intervals of time, meaning that the planet travels faster when it is closer to the Sun in its elliptical orbit. This occurs because the gravitational pull is stronger when the planet is closer to the Sun, which accelerates the planet and increases its orbital speed. Therefore, the correct answer to the question is: b) move fastest when near the Sun.

Sustainability must incorporate ways of halting pollution entirely Sustainability incorporates methods of decreasing pollution. Sustainability needs to find a way to increase pollution. Sustainability uses the energy of pollution to drive the economy Sustainability and pollution will both increase in the future.
Answer:
Sustainability must incorporate ways of halting pollution entirely
Explanation:
The concept of sustainability in the production process means that an economic activity is performed without causing further damage to the environment. For example, for a paper mill it consumes 100 trees in the production process. To be considered sustainable, this firm must generate the benefit that these trees brought to the environment. This can be done in many ways, such as planting trees or directing funds to environmental causes. In other words, an economic activity is considered sustainable if it generates benefits to the same extent as the harm caused by its activity. If the company has polluted the environment, it must take steps to reverse the pollution it causes to be sustainable.
Question 10 1pts Gravitational pull that causes things to turn right in the Northern Hemisphere; is known as the Air Pollution Coriolis Effect Conveyor Belt Jet Stream
Answer:
Gravitational pull that causes things to turn right in the Northern Hemisphere is known as Coriolis Effect

What are the mechanisms whereby a) plants affect weathering, and b) weathering affects atmospheric CO2concentrations? Write the major equations involved for the most important reactions.
Answer:
Explained below.
Explanation:
Plants roots break the rocks and soil from the bottom and derive up nutrient form the steam to leaves and its due to this factor the planet are considered as an agent in biological weathering like animals that bring up the soil particles and displace the soil matter and expose the rocks at greater depths. Weathering is directly affected by the atmospheric conditions such as the concentration of atmospheric pollutants by the human-induced factors and the weathering created due to the erosion of base rocks and this happens in chemical weathering phases.An equation is given for reference

b.Be able to indicate the direction that wind will move in the upper and lower atmosphere, in the northern and southern hemisphere, around high and low pressure systems.
Answer:
(A) The Coriolis force is the force that acts on an object due to the rotation of the earth. The basic rule of this force is that it causes the deflection of wind when it blows from one place to another. The magnitude of this Coriolis force directly depends upon the latitude at which the object is located. This force is maximum at the poles and minimum at the equator.
(B)- Correct answer is Option (2) i.e this force can indicate the wind direction in the northern and southern hemisphere,
When the air in a particular area becomes warm due to heating, then it becomes less dense and rises up. This area forms a low pressure zone. This low pressure zone is filled with the air from the high pressure zone. The wind that blows from the region of high pressure to the region of low pressure does not move in a straight line. Due to the Coriolis force, this wind gets deviate and reaches the low pressure zone.
Thus, this force indicates the direction from which a wind blows in both the southern and the northern hemisphere. In the southern direction it moves in anticlockwise direction, whereas in the northern hemisphere it moves in clockwise direction.

plate boundary, what is the result O A mountain belt, like the modern Himalayas 0 A continental volcanic arc like the modern Andes. O Earthquakes, but no volcanism, like the modern San Andreas Fault in California.
Answer:
All the above
Explanation:
The plate boundary is the result of movements in the latest either through the divergence, convergence or the formation transform or rift valleys. The occurrence of the earthquakes and volcanic eruptions around the zones of mountain belts and various other events led to the volcanic arcs. A Mountain belt-like system of the Himalayas in Northern India is a result of the orogenic upliftment of sediments bright from the Tethys sea and splitting of the Indian subcontinent from the Australian plate to collide with the Eurasian plate. A continental volcanic arc forms due to the lava a magma that originates in the form mantle plums produced due to the burning of the lighter plate over the oceanic plate and volcanoes like the Andes form when the slab pulls the plate to the deep trenches. And the san Andreas fault in California is a transform fault with dextral movements on both sides as the landmass is drifting westwards.If the number of electrons in an atom is 39 and the mass number for the same atom is 90, calculate the the following for this atom: a) the number of protons b) the atomic number c) the number of neutrons d) What is the identity of this element?

how are the products and resources we consume actually produced?
fquestion from Environmental Science a study of interrelationships
Answer:
Product and resources are dependent on the environment such as fish , vegetables and milk.
Explanation:
As today's consumption pattern is determined by the environmental resource base as the real issue is not the type of consumption but the nature of consumption itself. About 85% of paper products that we consume comes from the natural resource on land. Similarly, many experts predict that the population will decrease at some point in time due to the resource that consumed are already reached its full capacity. Changes in consumption patterns have a direct bearing on the growing demands of people in various parts of the world. Resources and products that are manufactured from the raw form to finished from a that includes the carbon content and their daily consumption leads to overconsumption of resource.Answer:
Today, the production of goods, resources and services takes place through production chains, where 3 clearly differentiated productive sectors are identified:
1- the primary sector is in charge of the production of raw materials, through their generation and extraction from the natural environment to be used for the production of products or direct consumption by society. Example of primary activities can be agriculture or mining.
2- the secondary sector is the one that transports and processes the raw materials, finalizing the transformation of the raw material into a new product that satisfies a particular social need. Industrial activity is a secondary activity, which modifies these raw materials by launching processed products onto the market.
3- Lastly, the tertiary sector is in charge of marketing the processed and / or natural products directly for human consumption, that is, they bring goods and services closer to consumers. A clear example of tertiary activity is that of supermarkets or advertisers.
7. What is the angle between the ecliptic and celestial equator? Why is that important?
Answer:
The ecliptic plane is inclined at 23.5° with respect to the celestial equator because of the tilt of the Earth's rotation axis with respect to the plane of its orbit around the sun.
The angle between the ecliptic and celestial equator is known as the obliquity of the ecliptic.
Why is the angle between the ecliptic and celestial equator important?The angle between the ecliptic and celestial equator, known as the obliquity of the ecliptic which is approximately 23.5 degrees. This angle plays a crucial role in determining the changing seasons on Earth.
The Earth's axis is tilted relative to its orbital plane around the Sun causing the Sun's position in the sky to vary throughout the year. This tilt is responsible for the different lengths of daylight and varying intensity of sunlight that lead to the four distinct seasons.

Why are nighttime mixing ratios of ozone always nonzero in the background troposphere (think of rural areas) but sometimes zero in urban areas?
Answer:
The newly transmitted toxins blend with different poisons, including ozone, present in foundation air, and a confounded procedure of synthetic responses and nonstop weakening happens.
Introduction to ozone instigates impacts on well being and the earth, causing respiratory challenges in touchy individuals and conceivable harm to vegetation and biological systems.
Night time mixing ratios are always nonzero in the background troposphere but sometimes zero in urban areas.
Photo chemical pollution is formed from emissions of nitrogen oxides [tex](NO_x, where NO_x = NO + NO_2)[/tex] and of volatile organic compounds (VOCs) and carbon monoxide (CO) in the presence of sunlight.
Final answer:
At night, the background troposphere maintains nonzero ozone levels due to consistent low-level production and fewer pollutants that destroy ozone, whereas urban areas may have zero ozone levels at times because nighttime reactions can consume ozone without the presence of sunlight to produce more.
Explanation:
The presence of nighttime mixing ratios of ozone being nonzero in rural areas but sometimes zero in urban areas is due to differences in ozone production and destruction processes. In the background troposphere, ozone is produced by the interaction of sunlight with oxygen molecules and various pollutants such as volatile organic compounds (VOCs) and nitrogen oxides (NOx) which are less prevalent in rural areas. This results in a constant, albeit low, level of ozone at night.
In contrast, urban areas have higher concentrations of these pollutants due to more motor vehicle exhaust, industrial emissions, and higher energy consumption leading to more intense photochemical reactions. This can lead to higher daytime ozone levels. However, at night, the lack of sunlight halts the production of ozone, and urban areas may have more substances that react with and consume ozone, such as nitric oxide (NO), which can lead to occasionally zero ozone levels at night. The nocturnal ozone levels in urban areas can be more variable due to these factors.
