Science Vocabulary- Weather Aquifer Spring atmosphere An underground layer of rock or soil filled with water. Some groundwater seeps out of the ground. *happens when the water table meets the surface. Holes dugbelow the water table ---stores water for people to use. Storage areas for freshwater supplies (for a town/city)---can be natural or man made. the air that surrounds Earth troposphere the layer closest to Earth’s surface air pressure is the force put on a given area by the weight of the air above it weather Is what the air is like at any given place and time Climate Is the average weather pattern of a region. barometer measures air pressure anemometer humidity Measures wind speed the amount of water in the air evaporation the changing of a liquid into a gas condensation the changing of a gas into a liquid Wells reservoirs relative humidity a comparison between how much water vapor is in the air and how much the air could hold---at a given time stratus clouds Clouds formed in a blanket like layer cumulus clouds are puffy clouds that appear to rise up from a flat bottom cirrus clouds Clouds formed at very high altitude out of ice crystals and have wispy, featherlike shape Fog a cloud at ground level precipitation any form of water particles that falls from the atmosphere and reaches the ground wind air that moves horizontally Science Vocabulary- Weather convection cell is a part of the atmosphere where air moves in a circular pattern because of unequal heating and cooling sea breeze a wind blows from the sea toward the land land breeze a blows from land toward the water coriolis effect the curving of the path of a moving object caused by Earth’s rotation Isobar a line on a weather map connecting places with equal air pressure air mass a large region of the atmosphere where the air has similar properties cold front Cold air moves in under a warm air mass brings brief heavy storms (possible thunderstorms and strong winds) after the storm the skies are usually clearer and the weather is usually cooler/drier warm front warm air moves in over a cold air mass brings light steady rain or snow precipitation may last for days may bring fog after the weather is usually warmer /more humid The most common kind of severe storm Thunderstorm Tornadoes the most violent thunderstorms often spin off even more dangerous storms hurricane a very large, swirling storm with very low pressure at their center storm surge a great rise of the sea along a shore its main cause is low air pressure Science Vocabulary- Weather aquifer spring wells reservoirs atmosphere An underground layer of rock or soil filled with water.
