Rocks of the Earth

The rock cycle

The continual process by which rocks change from one type to another

Metamorphic rocks

Coarse-grained

sandstone

Fine-grained

Shale

A rock that is completely transformed or changed from an igneous or sedimentary rock under intense heat or pressure

Sedimentary rocks

formed by the cementing and hardening of layers of sediments under pressure from the overlying layers

Igneous rocks

Fine-grained igneous rocks

Eg. Basalt

formed when lava cools and hardens quickly on the Earth's surface.

Coarse-grained igneous rocks

Eg. Granite

formed when magma cools and hardens slowly in the Earth's interior

Igneous rocks are magma that has cooled and hardened, either beneath or above the Earth's surface

Rocks are solid materials of the Earth's crust
