How do plants weather rocks?

• Plants don't weather rocks.

• When roots grow into cracks of rocks and expand the rock breaks.

• When the plant moves water from the roots to the leaves, the rock breaks.

Fastest chemical weathering =

• hotter, humid environments

Fastest physical weathering =

• colder, dry environments

• colder, wet environments

• hotter, dry environments

• hotter, wet environments

Which type of weathering involves the breakdown of rocks through chemical reactions, often involving water and atmospheric gases?

• Physical weathering

• Chemical weathering

• Biological weathering

• Mechanical weathering
