• pressure in the earth

• ice glaciers

• loose sand and strong wind

Features on the surface of the earth such as mountains, hills, dunes, oceans, and rivers:

• delta

• erosion

• landforms

• oceans

What is an example of a fast change?

• earthquakes

• deposition

• erosion

• water in a bottle

What is formed from buried remains of plant and animal life that were changed by millions of years of heat and pressure.

• Natural Resources

• Fossil Fuels

• Sand Dunes

• Electric Circuits
