3 Surface Water vs. Ground Water Surface water- sources of water found on the surface of the Earth (lakes, streams, oceans)Ground water- sources of water that have soaked into the ground (aquifers and wells)Surface Water vs. Ground Water
4 Examples of surface water Rivers systems (rivers, streams and tributaries) mountain source, flow downhill (gravity) to lower elevation.Watershed/Drainage basin-land area that provides water for river system.Examples of surface water
5 Flooding- when the volume of water increases to the point of overflowing its banks.
6 Continental Divide- highest ridge in the US Divide- ridge of land (high elevation) that separates water flow in various directions.Continental Divide- highest ridge in the US
7 Ponds and lakes- low areas where water pools/collects Lake formation- Volcanoes, glaciers, dams, oxbow (river meander that has been cut off) reservoir (storage for drinking water)Ponds and lakes- low areas where water pools/collects
8 Iceberg…straight ahead Pieces of glacier that have broken off (freshwater)Most of iceberg is underwater76% of Earth’s fresh water is in the form of ice.Iceberg…straight ahead
9 Water that is absorbed into the ground through pores (holes/spaces between rocks, sand etc.) Groundwater
10 Permeable vs. non permeable Soil has layers to itPermeable- layers of soil which allow for water to pass throughImpermeable- layers of soil which do not allow water to pass through.Permeable vs. non permeable
