Types of Rocks
Igneous rocks
-
Intrusive
BASALT 
hard, dark coloured rock containing small minerals
ANDESITE grey rock with bigger minerals
RHYOLITE a light coloured rock rich in quartz
This type of rocks solidifiesunder the surface of the earth.They have time to solidify,so big minerals were formed. Each extrusive rock has its intrusive pair.
They originate inside the earth where they are under great pressure. They form when molten rock cools and solidifies(megszilárdul). Crystals form on cooling and the rocks are called crystalline rocks.
