In this model of the rock cycle, A represents

.

A) Sedimentary

B) Weathering

Explanation:

A sedimentary soil/rock is formed when carrying agents such as wind or water carries rock pieces or soils particles from faraway places and deposit them at one place through a process known as lithification. However, increased pressure and temperature causes weathering of rocks. Changing temperature causes a rock to expand or cool alternatively thereby giving rise of internal stresses. While exfoliation is caused on increasing pressure.
