Erosion • Erosion is the removal of rock particles from a location. • Caused by water, wind, ice, or gravity.

WATER EROSION Water sources such as rivers, streams, ocean tides, and runoff can move rock particles away. .

WIND EROSION Sometimes the wind can move rock particles away: this can lead to dust storms!

Lets Rock! THE ROCK CYCLE

3 Types of Rocks There are 3 different types of rocks; Igneous Sedimentary Metamorphic

Igneous Rock Igneous rocks are formed by magma and lava as it cools. Igneous rocks form in two different ways. Rock that comes from lava cools very fast and can either be very light and airy or the rocks can be glassy. Rocks that come from magma are formed under ground. They are often times very hard and have more colors.

Igneous rock

Sedimentary Rock Sedimentary rock is made when sediments (sand, gravel, and dirt) are pressed together over time and become a rock Sedimentary rock is formed in layers.

Sedimentary Rocks Limestone Shale Sandstone Granite

Metamorphic Rock Metamorphic rocks are made from other rocks. Heat and pressure help change an igneous or sedimentary rock into a new kind of rock (think about how a caterpillar becomes a butterfly)

PARTS OF ROCKS

Rocks have many different parts Rocks can be sorted into groups by looking at their parts. Some rock parts are: Crystals Grains

Crystals are different atoms that are formed in a pattern. They can be big or small, fat or thin.

Grains are smaller pieces of rock or sediment. Grain size is something that is used a lot to help decide the rock type.
