Answer 1

Answer:

The composition usually reflects the composition of the magma, and thus provides information on the source of the rock.

The chemical composition of the magma determines the minerals that will crystallize and their proportions.

Answer 2

Igneous rocks, e.g. granite (coarse crystals) and basalt (fine crystals), were formed from the very hot molten material. The minerals (chemical compounds) in these rocks are mostly in the form of crystals. Igneous rocks are very hard and usually weather very slowly.
