What is aquifer?
The process of eroding or being eroded by wind, water, or other natural agents.
What is erosion?
Gaseous compounds that absorb and emit infrared radiation, trapping heat in the Earth's atmosphere and preventing it from escaping into space.
What is greenhouse gases?
The clearing or thinning of forests by humans, usually for non-forest uses.
What is deforestation?
Energy from a source that is not depleted when used, such as wind or solar power.
What is renewable energy?
An area or ride of land that separates waters flowing to different rivers, basins, or seas.
What is watershed?
The action of rotating around an axis or center.
What is crop rotation?
Rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm.
What is acid rain?
The process of replanting an area with trees.
What is reforestation?
A renewable energy source that uses the kinetic energy of wind to produce electricity or mechanical power.
What is wind power?
The underground boundary between the soil surface and the area where groundwater saturates the spaces between sediments and cracks in rock.
What is water table?
The process of increasing the concentration of salt in soil or bodies of water.
What is salinization?
A type of air pollution that occurs when nitrogen oxides and hydrocarbons react with sunlight to create ozone and other reactive chemical compounds.
What is photochemical smog?
Cut down and remove every tree from an area.
What is clear-cutting?
A form of energy released from the nucleus.
What is nuclear energy?
The supply of water to land or crops to help growth, typically by means of channels.
What is irrigation?
An agricultural practice that involves building rigged platforms, or terraces, across hillside to create flat area for growing crops.
What is terracing?
A layer in the earth's stratosphere at an altitude of about 6.2 miles containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun.
What is ozone layer?
What is sustainable development?
A natural fuel such as coal or gas, formed in geological past from the remains of living organisms.
What is fossil fuels?
The process of removing salt from seawater.
What is desalination?
A farming technique that involves plowing or planting across a slope's elevation contour lines.
What is contour plowing?
Microscopic solid or liquid particles that are suspended in the air or water.
What is particulate matter?
The uncontrolled expansion of urban areas.
What is urban sprawl?
The use of falling or fast-running water to produce electricity or to power machines.
What is hydropower?
