Question

Which is one way that mechanical weathering influences chemical weathering?

A.
Plants secrete acids that create holes in iron-rich rocks, thereby exposing them to moisture in the air, which causes the rocks to rust.

B.
The roots of plants fit into cracks of iron-rich rocks, exposing them to moisture in the air, which causes the rocks to rust.

C.
Winds break away layers of rock, exposing them to water for ice wedging.

D.
Acids in the rain create holes in the rock, which allows water to get inside for ice wedging.

Answer 1

Mechanical influencing chemical:
Falling rocks break, shatter, crack and grind up rocks, thereby exposing more surface area to chemical weathering.

The repeated freezing and thawing of water in cracks can further pry them apart so organisms can gain a foothold and wear the rocks away through bio-chemical reactions.

Chemical influencing mechanical:
Dissolving weathering can weaken some rock structures, thereby allowing gravity to cause them to break and fall.
