Term
Mechanical Weathering
Definition

type of weathering in which rock is physically broken into smaller pieces.

The causes of this weathering include:

  • freezing and thawing
  • release of pressure
  • plant growth (roots, roots, roots)
  • Actions of animals
  • Abrasion (the grinding away of rock by other rock particles carried in water, ice, or wind)
Term

Definition

the process that breaks down rock through chemical changes.

The cause of this weathering include:

  • Action of water
  • Action of oxygen
  • Action of carbon dioxide
  • Living organisms
  • Acid rain
Term
Soil
Definition
It is a mixture of rock particles, minerals, decayed organic material, water, and air.
