THE WATER CYCLE (REVIEW!)https://www.youtube.com/watch?v=oaDkph9yQBs
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)
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.
FLOODING- WHEN THE VOLUME OF WATER INCREASES TO THE POINT OF OVERFLOWING ITS BANKS.

CONTINENTAL DIVIDE- HIGHEST RIDGE IN THE US
Divide- ridge of land (high elevation) that separates water flow in various directions.
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)
ICEBERG…STRAIGHT AHEAD
Pieces of glacier that have broken off (freshwater)
Most of iceberg is underwater
76% of Earth’s fresh water is in the form of ice.

GROUNDWATER
Water that is absorbed into the ground through pores (holes/spaces between rocks, sand etc.)
PERMEABLE VS. NON PERMEABLE
Soil has layers to it
Permeable- layers of soil which allow for water to pass through
Impermeable- layers of soil which do not allow water to pass through.
AQUIFER
Underground source of stored water
Major aquifers throughout the United States

IDAHO AQUIFERS
WELLS AND SPRINGS
Spring- water that flows from the water table reaches the surface
Well- feature used to bring ground water to the surface through digging to the water table.
