Rocks and Minerals

Before we can talk about rocks, we need to know what makes up the earth, since rocks form on the earths surfaces!

Rocks and the Earth

Rocks and Minerals

Every kind of rock is made of two or more minerals, so we need to know where minerals form on the earth!

Hello Students!In science, we will be focusing on rocks and the rock cycle! This includes Igneous rocks, Sedimentary rocks, and Metamporphic rock.We will examine how these rocks fit into the cycle itself :)

Essential Questions:1. What can rocks tell us about the Earth?2. Why should we study rocks?3. Why do rocks change forms?

Igneous Rocks

Metamoprhic

Igneous rocks are made from lava and magma that has cooled

Metamorphic rocks are formed when other kinds of rocks undergo great heat or pressure

Sedimentary rocks are formed when other kinds of rocks undergo great heat or pressure

Sedimentary

All three of these types of rocks make up the rock cycle and are at different stages within the cycle
