science 8 & 9
| Question | Answer |
|---|---|
| air masses | sections of air with nearly the same temperature and moisture |
| air pressure | the forces of air pushing on an area |
| atmosphere | the blanket of air surrounding Earth |
| cirrus clouds | clouds that have a wispy, feather like shape |
| cloud | tiny drops of condensed water in the atmosphere |
| cold front | when a cold air mass pushes under a warm air mass |
| CUMULUS CLOUDS | PUFFY CLOUDS THAT SPEAR TO RISE FROM A FLAT BOTTOM |
| ESTUARY | the place where fresh water and salt water meet |
| filtration | passing a liquid through materils that remove impurities |
| groundwater | water stored in teh cracks and spaces of underground rock |
| humidity | the measurement of how much water vapor is in the air |
| ice cap | a thick sheet of ice covering a large area of land |
| irrigation | a way of getting water into the soil by artifical means |
| precipitation | water in the atmosphere that falls to earth |
| stationary front | a boundary between air masses that don't move |
| stratus clouds | clouds that form in layers |
| tide | the rise and fall of ocean water levels |
| warm front | a boundary between air masses where the warm air mass slides up and over the cold air mass |
| water table | the upper area of groundwater |
| water vapor | water in a gas state |
| wave | an up and down movement of water |
| Where is most of earth's fresh water found | in groundwater |
| fresh water is found in | rivers lakes and streams |
| plants get their water from | soil water |
| the fruits and vegetables plants produce | contain quite a bit of water |
| almost all of our water is found in | the world's oceans - it is salt water |
| the oceans never overflow because | the lose water through evaporation |
| particles of water go through the process of evaporation as they | absorb heat energy |
| the sun's energy causes liquid water to | evaporate |
| at low tempertures liquid water can become | solid ice by freezing |
| water is found surrounding Earth | in the atmosphere |
| when water loses heat energy, | it will condense |
| the states of water are | gas, liquid, solid |
| the atmosphere over a body of water holds more water vapor than | the atmospher over a desert |
| you can conserve water by | using smaller amounts and fixing leaky faucets |
| most water polution comes from | industry, farming and humans |
| ocean tides are caused by the | pull of gravity between Earth, the Moon and the Sun |
| the Moon's orbit around the Earth causes daily changes in | the ocean tides |
| rain, snow, sleet and hail are | types of precipitation |
| for a well to produce water its bottom must be | below the water table |
| air is made up of | 78% Nitrogen, 21% Oxygen and 1% other gases |
| the climate of an area near a large body of water is mainly | cloudy, rainy, cooler summers and warmer winters |
| when there is rain for several days it may be a result of | a stationary front |
| large streams of water tha flow in the ocean are called | currents |
| the lowest part of a wave is called the | trough |
| in the Northern Hemisphere warm currents move in a | clockwise direction |
| the coastline is built up and moves out toward the ocean as a result of | deposition |
| areas with no public disposal systems have | septic tanks |
| there is wind on Earth because the surface of Earth | is unevenly heated |
| When a cold air mass meets a warm air mass the cold air mass forces | the warm air mass upward, possibly resulting in violent weather |
| the troposphere, strosphere, mesophere and the thermosphere are | layers of the atmosphere |
| if you see high or low pressure areas on a weather map you can predict the weather will be | windy |
| El Nino is a phenomenon that occurs every 3 to 7 years when | ocean water along th coast of Peru becomes warmer than usual. This changes air circulation in the atmosphere and weather pattern around the world. |
| In 1997 & 1998 the eastern US and California experienced heavy rains and flooding as a result of | El Nino |
| all fronts consist of a warm air mass and a | cold air mass |
| What is weather | the day to day changes in temperature and conditions |
| climate | the typical wather for a specific area over a long period of time. |
