Groundwater And Running Water

infiltration

Decreased precipitation could impact water supply available for humans.

oceans, glaciers, groundwater, non-glacial ice and snow, lakes, rivers.

Almost all of Earth's surface water exists in the oceans.

as ice at Earth's surface

The hydrologic cycle describes how liquid and gaseous water move between the ocean, atmosphere, and land.

Ocean water evaporates to form gaseous water and moves into the atmosphere, where it condenses into liquid water and falls out of the atmosphere to land as rain.

The atmosphere would contain less water.

The oceans would become smaller.

Drainage basins only contain one river.

a boundary, usually a hill or mountain, where water will flow in opposite directions on either side

an area in which all water falling in it flows out through one location

a river that feeds into another river

the primary river flowing out of a drainage basin

a Divide

a Watershed

a Tributary

a Trunk Stream

Erosion occurs where water is moving the fastest along the outside of the loop. Deposition occurs where water is moving the slowest along the inside of the loop.

meandering stream

downcutting

undercutting and lateral erosion

Deposition occurs on the inside of the meander, whereas erosion occurs on the outside.

a meander that has been cut off from the original stream channel

Oxbow lakes form when one meander erodes into another, cutting off water to part of the stream channel.

a landscape feature formed after an oxbow lake dries up

rolling, sliding, bouncing

clay

ions

gravel and sand

bed load, suspended load, dissolved load

the fine-grained particles that travel in the water column above the stream bed

ice sheets and glaciers

Water in a groundwater system is stored in subsurface pore spaces and fractures.
