Answer: mechanical weathering
Explanation:
Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.
Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.
Water is an important agent of mechanical weathering, in either liquid or solid form.
Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.
The cell cycle is the most important process in the growth of the organisms, so its control is very complicated, since even a small mistake can have a huge importance for the cell. ... Everytime any cell reaches the S phase, there is no more limitation for it and DNA replication and mitosis always take place.
