If a layer was deposited but does not appear in rock record, what has occurred

a. eruption
b. folding
c. erosion
d. faulting

Option (C)

Explanation:

Erosion is a process which describes the transportation of materials such as rock fragments, soil particles and other substances, from one place to another.

The process of erosion occurs after the weathering of rocks, which means that the rock fragments are weathered or broken down due to various physical and chemical processes.

The sediments are eroded with the help of agents such as wind, water and ice and are deposited in a new place and over a due course of time forms sedimentary rocks. For example, sandstone, limestone and shale.

Thus, if a layer was initially deposited but it is absent in the rock record, then it signifies that the layer is eroded.

Thus, the correct answer is option (C).

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
