Igneous Rocks

Front

What are Igneous Rocks?

Back

Rocks formed from the cooling and solidification of magma or lava.

Front

What is the difference between magma and lava?

Back

Magma is molten rock found inside the Earth, while lava is magma that has reached the Earth's surface.

Front

What texture do rocks formed from lava typically have?

Back

Fine-grained texture due to rapid cooling.

Front

How do Intrusive Igneous rocks form?

Back

They form from magma that cools slowly beneath the Earth's surface, resulting in coarse-grained texture.

Front

What is Pumice?

Back

A type of volcanic rock that is light and porous, often used as a skin abrasive.

Front

What is Granite?

Back

A common type of intrusive igneous rock used for building materials.

Front

What is the cooling rate of Extrusive Igneous rocks?

Back

They cool quickly when lava erupts on the surface.

Front

What is an example of an Extrusive Igneous rock?

Back

Basalt.

Front

What is an example of an Intrusive Igneous rock?

Back

Granite.

Front

How does the cooling rate affect the grain size of igneous rocks?

Back

Faster cooling results in smaller grains, while slower cooling results in larger grains.
