Question

1. what is the rocks? classify ignoring rocks?​

Answer 1

Answer:

Igneous rocks are formed by the cooling and hardening of molten magma. Extrusive igneous rocks form when the magma, called lava once it reaches the surface, flows onto Earth's surface.

Answer 2

Answer:

A rock is a solid mass of geological materials. ... Sedimentary rocks form when fragments of other rocks are buried, compressed, and cemented together; or when minerals precipitate from solution, either directly or with the help of an organism. Metamorphic rocks form when heat and pressure alter a pre-existing rock.

Explanation:

As has already been described, igneous rocks are classified into four categories, based on either their chemistry or their mineral composition: felsic, intermediate, mafic, and ultramafic. The diagram in Figure 3.16 can be used to help classify igneous rocks by their mineral composition.
