Question

How does chemical weathering make it easy for mechanical weathering to occur

Answer 1

Chemical weathering softens rock making it easier to break by mechanical weathering. ... Oxygen combines with iron in rocks to form rust. according to google :)

Answer 2

Chemical weathering can make mechanical weathering easy by changing the chemical composition of the rock.

The mechanical weathering of hard rocks is tough and takes time and the mechanical weathering of soft rocks takes less time.

The softness and hardness of the rocks depends on the chemical composition of the rocks. The chemical weathering changes the chemical nature of rocks and hence makes it easier to break down into smaller portions.
