What is the breaking apart of rock?

What is the outermost layer Earth?

What is the natural process of moving rock and sediment?

The soil layer that has less humus and fewer living things.

The area directly above the focus of an earthquake.

A large mass of moving water caused by a strong earthquake under the ocean.

This layer is a mixture of humus and sediment; worms, insects, and animals live here.

What is the mixture of rock, sediment and organic matter?

What are large areas dividing the earth's surface?

The exact place an earthquake occurs

These can be formed when continents collide.  They release magma, cinders, ash and gases.

These are formed when animal tracks and imprints of plants are made in sediment.

What do we call the melted rock in the mantle of the earth?

Rock formed when magma cools and hardens below the Earth's surface or after a volcano erupts.

This rock is formed by heat and pressure.

Formed when sediment builds up and presses on lower layers of sediment.

Soil layer made up of decaying plants and animals.

These are large cracks in the earth's surface.

What is the third layer of Earth?
