The height of the waste heap is 120 m, and the process of denudation of rocks occurs at a speed of 51 cm / year.

The height of the waste heap is 120 m, and the process of denudation of rocks occurs at a speed of 51 cm / year. What will be the height of the waste heap in 25 years?

Denudation is a set of processes of destruction of rocks on the surface of the earth’s crust and the transfer of products of destruction to a lower level, where they are deposited.
Let’s determine how much the waste heap will collapse:
25 years × 51 cm / year = 12.75 m
Let’s determine the height of the waste heap in 25 years:
120 m – 12.75 m = 107.25 m
Answer: In 25 years, the height of the waste heap will be 107.25 m.
