A rock is a naturally occurring solid aggregate of one or more minerals or mineraloids.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

Explain the process of rock formation for igneous rocks.

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).
