*There are three different types of rocks - igneous, metamorphic, and sedimentary.
*The three rock types are different in the way in which they are formed.
*Igneous rocks are formed from melted minerals that have cooled and hardened.

Explain how waves, wind, water, and glacial movement shape and reshape the land surface of the earth by eroding rock in some areas and depositing sediments in other areas.
*Rock can be eroded by wind, water (including waves), and glacial movement.
*Processes of erosion, in part, determine the shapes of landforms.
*Fragments of rock that are produced by erosion and transported are called sediment.
*Sediment that is transported by the energy of wind or water is deposited when the energy level decreases.

Describe how soil is a mixture, made up of weather-eroded rock and decomposed organic material, water, and air (WAMO—water, air, mineral, organic).
*One of the components in soil is mineral, which is made from many tiny pieces of eroded rock.
*Another component in the soil is the organic material that comes from decaying plants and animals.
*Minerals and organic material make up approximately half of soil.

Explain how a compass works using the magnetic field of the earth, and how a compass is used for navigation on land and sea.
*A compass is composed of a small, lightweight magnet, called a needle that is balanced on a point.
*Compasses can be used for navigation from any point on the earth due to the earth's magnetic field.
