Rock Story Drama

In your scene, demonstrate many of the qualities that your rock has. Use the chart below to help you review these qualities.

Sedimentary

Formed from eroded particles (these particles are sometimes blown away by the wind)

Particles eventually settle on land and in bodies of water

Particles compact layer upon layer and eventually harden to
form rocks

Large amounts of particles settle as sediment from rivers that empty into larger bodies of water

Fossils form in sedimentary rocks

Igneous

Formed by the cooling of magma coming from far beneath the Earth’s crust

Magma is under very high pressure and heat

Magma may cool under the surface—this is called plutonic igneous rock

Magma that flows on the surface cools quickly to form a lava flow — the resulting rock is called volcanic igneous rocks

Metamorphic

Formed when rocks are changed by extreme heat and pressure
deep in the Earth

Often, these changes are so extreme that the rock’s original identity is obscured

If heat and pressure are extremely high, some minerals may react chemically with each other and form new minerals

Foliation (colour banding) is a physical characteristic of some
metamorphic rocks
