A rock containing a metal together with impurities is called an ore

What rocks are organic sediments

produces large amounts of fluid lava that explode from the volcano like a water fountain

region of space affected by the earth's magnetic field

a mixture of broken-down rocks and decomposed plants and animals

This law shows the distance between each planet and the time it takes to complete one orbit.

rock formed from mud or clay, often ground up and used to make bricks

underwater mountain ranges where plates of the earth's crust are thought to be moving away from each other

petroleum comes from two words "rock oil"

What rocks are mechanical sediments

A sedimentary rock + heat= metamorphic rock
