How do igneous rocks form?

• from tiny particles

• water and air help it form

• magma or lava cools and hardens

• heat/pressure

How are sedimentary rocks formed?

• Molten rock with earth

• Gas bubbles form and get trapped

• compacting and cemenation.

• heat/pressure

How are metamorphic rocks formed?

• heat/pressure causes buried rock to change into new rock

• formed to be used as tools

• does not form from heat and pressure

• can form fossils

What is the rock cycle?

• How we test how hard a rock is

• How we test the age of rocks

• Rocks changing into different types of rocks

• Rocks being thrown in a circle

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

The three groups of rocks are classified by

• How they form

The process when rocks break into smaller pieces due to exposure to natural elements is called

• erosion
• weathering
• sediments
