Question

Identify/describe how the process of physical weathering breaks down materials at the Earth's surface (by the following change agents: water movement, freezing, abrasion/pressure, exfoliation. plant growth, and animals).

Explain the role of each factor in chemical weathering (water, acid, and air).

Answer 1

Exfoliation: When temperature of rocks rapidly changes that can expand or crack rocks.

Freeze-Thaw: when water gets into a crack, and it freezes ; the crack gets wider

Plant Growth: this is when a seed falls into a crack in a rock, and breaks apart the rock with its roots.

Animals: small animals like moles and mice can burrow into a rock and crack it open
