Melting above the subducted slab produces mafic magma, as described above, yet intermediate rocks (andesite, diorite) between oceanic and continental lithosphere, explain how this intermediate magma forms.
(a) A relatively small amount of intermediate magma occurs in volcanic island arcs. Remembering that melting above the subducting slab produces mafic magma, explain the origin of the intermediate magma.
(b) Much more intermediate magma erupts in continental arcs. Why?

Answers

Answer 1

Answer and Explanation:

A. Intermediate magma occurs with the partial melting of the overlying ultramafic oceanic crust. This melting is caused by the fluids released by the subducted slab. As a result of this parvial melt there is a magmatic differentiation where the formed magma leaves a material residue, called intermediate residue, which is assimilated by the basaltic magma, thus forming the intermediate magma.

B. This is because as the intermediate magma is produced, the continental crust is either assimilated by it, or melted and assimilated by the magma.

Describe the change in the Moon's phase that takes place over the span of one cycle.

Answers

Answer:

Las fases lunares son los cambios en la forma de la parte iluminada de la Luna cuando es vista por un observador en la Tierra. Estos cambios son cíclicos de acuerdo a la posición de la Luna respeto a la Tierra y al Sol. ... A medida que la Luna orbita alrededor de la Tierra, parece que continuamente cambia de forma.

Explanation:

Answer:

A different section of the moon's face is lit up by the sun, causing it to show different phases.

Explanation:

How do the phases of the moon change?

The moon's location changes daily as it goes through its 29-day orbit. It is between the Earth and the sun at times and behind us at other times. As a result, the sun illuminates a different area of the moon's face, causing it to show different phases.

What happens to the moon's phases during the period of a month?We don't see the Moon as it moves between the Sun and the Earth because the side reflecting the Sun is facing away from the Earth. It's the new moon.So, while it appears like the Moon is changing shape over the course of a month, this is not the case. The Moon's orbit around Earth causes the phases to change.Moon Phases-

Moon phases: New Moon, First Quarter, Full Moon, and Last Quarter

There are also four secondary phases: Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent.

After capital flight
Now, suppose that Mexico experiences a sudden bout of political turmoil, which causes world financial markets to become uneasy. Because people now view Mexico as unstable, they decide to pull some of their assets out of Mexico and put them into more stable economies. This unexpected shock to the demand for assets in Mexico is known as capital flight.
Shift the NCO curve to illustrate the effect of capital flight. Then, on the graph representing the market for loanable funds, shift the demand curve, the supply curve, or both to reflect the change caused by the shift in NCO.
Note: You will not be graded on your final placement of the curves on the graph, but you will need to shift them correctly in order to answer the questions that follow.
Determine the equilibrium interest rate after capital flight occurs, and enter it into the second row of the table. Then determine the level of NCO that occurs along the new NCO curve at the new equilibrium interest rate.

Choose the true statement about the nitrogen cycle.
a. Bacteria take nitrogen from the atmosphere and convert it into sugars.
b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
c. Nitrogen makes up about 22% of the atmosphere's composition.
d. Animals release nitrogen through urination and by dying.

Answers

The true statement about the nitrogen cycle is that: b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.

Nitrogen is a chemical element with the symbol "N" and it has an atomic number of 7.

Basically, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.

Nitrogen cycle can be defined as a repeating biogeochemical process which typically involves the interconversion or circulation of nitrogen and its compounds by the actions of both living organisms and non-living things in the environment such as nitrogen fixation and decomposition. Thus, it is biogeochemical process that converts nitrogen gas into organic substances and then back to nitrogen in air.

In the real world, it is known that the leaves of plants such as peanuts, soybeans and clover contain nitrogen in a very significant amount.

In conclusion, true statement about the nitrogen cycle is that nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
