What letter is the second layer of the rock? ​
Vadim26 [7]

Answer:

Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.

Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.

Which process could occur in maple trees to decrease the chromosome number in pollen cells from 52 down to 26?
dlinn [17]

Meiosis

Explanation:

The process in maple trees that decreases the chromosome number in the pollen cells from 52 to 26 is called meiosis.

Meiosis is an important cell division process in which diploid cells are turned into their haploid number.

  • In meiosis the cells divides into half and produces four daughter cells from the diploid 2n cells.
  • The cell divides twice here. It is common in all sexually reproducing cells.
  • It also occurs in all single celled organisms that reproduces sexually.
