Holly studied some soil at the bottom of a valley. The soil contained some roc

from the top of a nearby mountain. Explain how the particles could become part of the soil.

The particles will become a part of soil through the process of weathering.

Weathering is a natural process;

It is described as the physical disintegration and chemical decomposition of rocks to form sediments and soils.

In this process chunks of rocks will be broken down into smaller fragments and incorporated as soil.

During physical disintegration, chunks of rocks are broken down into smaller bits. Chemical actions reduces this bits even further.
