The Hydrologic Cycle

Review:
*Fossil Fuels - a natural fuel such as coal or gas, formed in the geological past from the remains
of living organisms
→ Greenhouse gases are contributing to global warming because they trap more of the Sun's
energy in the Earth's atmosphere (This smoke is a greenhouse gas)
→ Our dependence on burning fossil fuels, and releasing the carbon stored in them, means we
have been adding a lot more carbon dioxide to the air
*The Hydrologic Cycle - the sequence of conditions through which water passes from vapor in
the atmosphere through precipitation on land or water surfaces and ultimately back into the
atmosphere as a result of evaporation and transpiration
*Precipitation - any form of water that falls from
clouds and reaches the Earth’s surface
*Evaporation - the process of turning from liquid
into vapor
*Condensation - molecules of water vapor in the
air become liquid water
*Transpiration - water released into the
atmosphere directly from the leaves of trees and
plants

*The science of hydrology studies how water moves around and within Earth’s surface.
→ including drought, floods, groundwater, and the availability of clean drinking water.

Document Summary
*fossil fuels - a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. Greenhouse gases are contributing to global warming because they trap more of the sun"s energy in the earth"s atmosphere (this smoke is a greenhouse gas) Our dependence on burning fossil fuels, and releasing the carbon stored in them, means we have been adding a lot more carbon dioxide to the air. *the hydrologic cycle - the sequence of conditions through which water passes from vapor in the atmosphere through precipitation on land or water surfaces and ultimately back into the atmosphere as a result of evaporation and transpiration. *precipitation - any form of water that falls from clouds and reaches the earth"s surface. *evaporation - the process of turning from liquid into vapor. *condensation - molecules of water vapor in the air become liquid water.
