Earth Structures: Rocks

Rocks are

• Solid earth materials made of minerals

• Rock formed from cooled magma or lava.

• Rock that is formed from layers of sediments (may contain fossils) that are pressed and squeezed together until it hardens.

• Rock formed when exposed to extreme heat and pressure under ground.

Igneous rocks are

• Solid earth materials made of minerals

• Rock formed from cooled magma or lava.

• Rock that is formed from layers of sediments (may contain fossils) that are pressed and squeezed together until it hardens.

• Rock formed when exposed to extreme heat and pressure under ground.

Metamorphic rocks are

• Solid earth materials made of minerals

• Rock formed from cooled magma or lava.

• Rock that is formed from layers of sediments (may contain fossils) that are pressed and squeezed together until it hardens.

• Rock formed when exposed to extreme heat and pressure under ground.

Sedimentary rocks are

• Solid earth materials made of minerals

• Rock formed from cooled magma or lava.

• Rock that is formed from layers of sediments (may contain fossils) that are pressed and squeezed together until it hardens.

• Rock formed when exposed to extreme heat and pressure under ground.

Sediment is

• Solid earth materials made of minerals

• material (as stones, sand, mud, pebbles) carried onto land or into water by water, wind, or a glacier.

• Rock that is formed from layers of sediments (may contain fossils) that are pressed and squeezed together until it hardens.

• Rock formed when exposed to extreme heat and pressure under ground.

Rock cycle is

• Solid earth materials made of minerals

• material (as stones, sand, mud, pebbles) carried onto land or into water by water, wind, or a glacier.

• the process by which rocks of one kind change into rocks of another kind.

• Rock formed when exposed to extreme heat and pressure under ground.

How does sedimentary rock form?

• sediments cool

• sediments melt

• sediments seperate

• sediments compress

What is the difference between magma and lava?

• Magma is below ground.

• Magma is cool. Lava is hot.

• Magma comes out of Earthquakes. Lava comes out of volcanoes .

• Magma is solid. Lava is liquid

The picture shows a section of rock.

The stripes on the rock show that it

• has layers

• can grow plants

• is made from sand

• contains many fossils
