Earth's Surface

Earth's surface is the part of our planet that we interact with every day. This unit helps students explore the land and water that make up Earth's surface. The land is composed of rocks and soil. Water covers about 70 percent of Earth's surface. Much of it is salt water found in oceans. Fresh water can be found in lakes, ponds, rivers, and underground. Earth's surface is shaped into various landforms by gravity, wind, water, and the movements of Earth's crust. Earth's surface provides everything needed for life to thrive, including shelter, food, and water.
