Igneous Rocks Quiz

What is the process of formation of igneous rocks?

• Erosion and deposition of sedimentary rocks

• Metamorphism of existing rocks

• Solidification or crystallization of molten magma or lava

• Volcanic eruption and cooling of lava

What are the two main classifications of igneous rocks?

What is the texture of igneous rocks?

• Soft

• Coarse-grained or fine-grained

• Transparent

• Smooth

Which type of igneous rocks are formed from lava cooling on the Earth's surface?

What is the difference between extrusive and intrusive igneous rocks?

• Extrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface, while intrusive igneous rocks are formed from lava that cools quickly on the Earth's surface.

• Extrusive igneous rocks are formed from sedimentary rocks, while intrusive igneous rocks are formed from metamorphic rocks.

• Extrusive igneous rocks are formed from magma that cools quickly on the Earth's surface, while intrusive igneous rocks are formed from lava that cools slowly beneath the Earth's surface.

• Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface, while intrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface.

How are igneous rocks used in everyday life?
