Over time, rocks begin to break down to form soil. which of the following is a way that rocks can be broken down?
a.
wind erosion
b.
an eclipse
c.
thunder
d.
a full moon

The correct answer is A. Wind erosion

Explanation:

The soil is the substance that covers the surface of our planet, this is mainly formed as rocks break down which is called weathering. This phenomenon can occur due to the action of living organisms, due to chemical reactions or due to physical factors. In the case of physical factors, this includes collision, changes in temperature or pressure and wind erosion that occurs as the wind makes rocks and soil move and this movement can make rocks break down into smaller parts or become more prompt to break. Thus, one of the ways rocks can be broken down is through wind erosion.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.
