Answers
Answer:
1) The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
2) the warm air near the earth's surface expands. ... Thus, as warm air rises from the surface, cool air from above comes down to replace it. This results in a cyclic movement of air near the earth's surface.
3) A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. Monsoons cause wet and dry seasons throughout much of the tropics.
4) Atmospheric pressure is the force exerted on the Earth's surface by the column of air above the Earth. Atmospheric pressure is caused by the weight of air above the Earth's surface
5) Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth's own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.
6) Nitrogen comes from decaying plant material, automobile exhaust, fertilizers, etc. ... Oxygen comes from photosynthesis performed by plants and micro-organisms and decomposition of the ozone layer by chlorofluorocarbons. Carbon dioxide comes from burning fuels and wood and organisms performing respiration.
7) Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
1. The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere
2. The warm air near the earth's surface expands. becomes lighter and rises. ... Thus, as warm air rises from the surface, cool air from above comes down to replace it. This results in a cyclic movement of air near the earth's surface.
3. A monsoon is a seasonal wind which lasts for several months. The word was first used in English for the seasonal rains in the Indian subcontinent. These rains blow in from the Indian Ocean and Arabian Sea in the southwest bringing heavy rainfall to the area.
4. Atmospheric pressure is the air pressure which is exerted by the weight of air present in the atmosphere. Atmospheric pressure is due to the weight of air present in the atmosphere
5.
The Wind is air in motion. The Wind is caused by air moving from areas of high pressure to areas of low pressure. It is produced by the uneven heating of the earth's surface by the Sun. ... Cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow
6. Nitrogen comes from decaying plant material, automobile exhaust, fertilizers, etc. ... Oxygen comes from photosynthesis performed by plants and micro-organisms and decomposition of the ozone layer by chlorofluorocarbons. Carbon dioxide comes from burning fuels and wood and organisms performing respiration.
