Water Cycle & Climate vocabulary (9)
| Term | Definition |
|---|---|
| adiabatic | change in the temperature of a gas caused by expansion (cooling) or compression (warming) |
| angle of insolation | angle of the sun above the horizon |
| capillarity | ability of a soil to draw water upward into tiny pores |
| capillary water | water held within tha aerated zone of the soil above the water table |
| climate | average weather conditions over many years |
| continental climate | climate in which there are large seasonal changes in temperature due to the absence of nearby bodies of water that could moderate the climate |
| duration of insolation | length of time from sunrise to sunset that the sun is in the sky |
| El Nino | condition in the Pacific Ocean when seasonal upwelling of deep equatorial water does not follow its usual pattern (This can lead to unusual weather conditions over a large area.) |
| greenhouse effect | process by which infared heat waves are trapped in the Earth's atmosphere by gases such as carben dioxide and methane |
| greenhouse gases | gases such as carbon dioxide, methane, and water vapor, that trap heat in Earth's atmosphere and affect Earth's climate |
| groundwater | water that infiltrates the ground |
| infiltrate | seeps into, like water into the ground |
| insolation | electromagnetic energy that Earth receives from the sun; contraction of the words "incoming solar radiation" |
| insolation-temperature lag | time delay between maximum or minimum insolation and maximum or minimum air temperature |
| leeward | downward side of a mountain range (usually the side with less precipitation) |
| maritime climate | climate in which seasonal temperature changes are moderated by a large body of water |
| permeability | ability of a soil to transmit water |
| planetary wind belts | latitude zone of prevailing wind conditions caused by uneven heating of Earth and Earth's rotation |
| porosity | energy absorbed or released in a change in state |
| radiative balance | equilibrium between absorbed radiant energy and radiant energy given off |
| reflection | process by which energy waves bounce off a surface or interface |
| runoff | precipitation that is unable to infiltrate soil, so it moves overland into streams |
| transpiration | process by which living plants release waer vapor to the atmosphere |
| vertical ray | sunlight that strikes Earth from directly overhead (the zenith) |
| water (hydrologic) cycle | model of the circulation of water between the oceans, atmosphere, and land |
| water table | boundary at the top of the saturated zone within fractured bedrock or soil |
| watershed | drainage basin; the geographic area in which water drains into a particular stream or other bodies of water |
| windward | side of a mountain range where the air is forced to rise, leading to cloud formation and precipitation |
| zone of aeration | soil above the water table in which most of the interconnected pores are filled with air |
| zone of saturation | fractured rock or soil below the water table in which the pores are filled with ground water |
