Faahfaahinta casharka

Natiijada casharka

I can explain how igneous rocks form and describe features of different types.

Muuji qoraalka
The melting point of rock is very high. Melted rock is called either lava (on Earth's surface), or magma (underground). Extrusive igneous rock forms outside Earth's crust, while instrusive igneous rock forms inside the crust. Some substances form crystals when they freeze. Crystal size depends on the rate at which melted rock cools.
