Earth Science Igneous Rocks

This type of rock is formed when magma or lava cools

• Sedimentary

  Rock

• Igneous

  Rock

• Mineral

• Metamorphic

  Rock

This is a very hot substance formed within the earth

(molten or semi-molten material)

• Hot Plate

• Lava

• Mineral

• Magma

This is formed when Magma is released from the earth and cools on the earth's surface

• Magma

• Lava

A small cavity in an igneous rock causes this rock texture

(holes in the rock)

• Sponge

• Intrusive

• Extrusive

• Vesicular

When lava cools quickly it forms this rock texture

(grains are tiny)

• Fine Grain

• Coarse Grain

• Sandstone

• Mineral
