Answer» 1. An atmosphere is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. 2.Two gases make up the bulk of the earth's atmosphere:nitrogen( ), which comprises 78% of the atmosphere, andoxygen( ), which accounts for 21%. Varioustrace gasesmake up the remainder. 3.carbon dioxide creates greenhouse effect prominently. 4.Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy.Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. 5.Here are thethree main types of rainfall: ReliefRainfall. ConvectionalRainfall. FrontalRainfall. 6.Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. |
