Carbon Sink

a natural or artificial system that absorbs and stores more carbon from the atmosphere than it releases; takes in carbon

Carbon Source

process or activity that releases carbon dioxide (CO2) into the atmosphere; Releases carbon.

Carbon Source (examples)

volcanic eruptions, forest fires, and animal respiration, breathing.

Carbon sink (examples)

plants, the ocean and soil.

Photosynthesis

pulls carbon dioxide out of the air

Respiration (breathing)

puts carbon dioxide into the air.

snow, rain, sleet

forms of precipitation

Fog

Water droplets suspended in air near the ground; NOT considered precipitation.

Evaporation

the process by which a liquid, like water, turns into a gas (vapor) and rises into the atmosphere

Condensation

The process where water vapor cools and turns into liquid, forming clouds.

Transpiration

The release of water vapor from plants into the atmosphere.

Runoff

Water that flows over the land surface and into bodies of water without soaking into the ground.

Zone of aeration

the area above the water table where the soil or rock pores are filled with both air and water

Zone of saturation

The area in soil below the water table where all spaces are filled with water.

Ground Moraine

A layer of till (Glacier debris) left behind as a glacier melts and retreats.

Terminal Moraine

A ridge of debris deposited at the furthest point reached y the glacier.
