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.

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.
