Here's the breakdown:
* Minerals are the building blocks of rocks.
* Melting is the process of turning a solid into a liquid.
* Magma is molten rock found underground.
* Lava is magma that has erupted onto the Earth's surface.
Once magma cools and solidifies, it forms igneous rocks.
There are two main types of igneous rocks:
* Intrusive igneous rocks are formed when magma cools and solidifies beneath the Earth's surface. These rocks tend to have larger crystals because they cool slowly.
* Extrusive igneous rocks are formed when lava cools and solidifies on the Earth's surface. These rocks tend to have smaller crystals because they cool more quickly.
