  2. Water vocab • Ocean • a large body of salt water that surrounds a continent. Oceans cover more the two-thirds of the Earth's surface • Sea • a large body of salty water that is often connected to an ocean. A sea may be partly or completely surrounded by land. • Gulf • a part of the ocean (or sea) that is partly surrounded by land (it is usually larger than a bay). • Bay • a body of water that is partly enclosed by land (and is usually smaller than a gulf). • Channel • a narrow body of water that connects two larger bodies of water (like the English Channel). A channel is also a part of a river or harbor that is deep enough to let ships sail through. • Cove • small, horseshoe-shaped body of water along the coast; the water is surrounded by land formed of soft rock.

  3. Lagoon • a shallow body of water that is located alongside a coast and separated from the ocean by a strip of land or a sandbank. • Lake • a large body of water surrounded by land on all sides. Really huge lakes are often called seas. • Reservoir • a man-made lake that stores water for future use. • Pond • a small body of water surrounded by land. A pond is smaller than a lake. • Swamp • a type of freshwater wetland that has spongy, muddy land and a lot of water. Many trees and shrubs grow in swamps.

  4. Strait • a narrow body of water that connects two larger bodies of water. • Canal • a man-made waterway used for transportation or irrigation. • River • a large, flowing body of water that usually empties into a sea or ocean. • Waterfall • When a river falls off steeply • Estuary • where a river meets the sea or ocean. • Tributary • a stream or river that flows into a larger river.

  5. Water pollution • any contamination of water with chemicals or other foreign substances that are detrimental to human, plant, or animal health. • What sort of things cause pollution? • Factories • Sewage • Farm runoff • Natural Phenomenon • Littering

  6. What has caused a growth in water pollution and a loss of water? • Urbanization • Overflowing garbage dumps • Global warming • Unwise use of resources

  7. Case study – Big Sioux River • Tributaries: Rock River in northeast Sioux County, IA • Tributary to the Missouri River • The waterfall in Sioux Falls is what gave the city its name. • Pollution: mostly runoff from farms and manure from animals being raised. Also some pollution has come from erosion of soil on the banks of the river. • The major pollutants that have been identified are phosphorus and sediment • Why do we care?

  8. What can we do to help?
