How is igneous rock formed?

• Through compression

• By erosion

• From cooled magma or lava

• Through chemical reactions

Igneous rocks formed on or beneath Earth's surface originate from:

• Cold material

• Molten material

• Glacial activity

Which type of rock is formed from lava that erupted onto Earth's surface?

• Basalt

• Granite

• Limestone

• Shale

What process forms sedimentary rocks?

• Melting

• Solidification
