The answer is E, Troposphere.<\/p>\n
The troposphere is the lowest layer of Earth’s atmosphere, extending from the surface to an average height of about 12 kilometers (7.5 miles). It is where most weather occurs, as the air is warmest near the surface and cools with height. The troposphere is also where most of Earth’s water vapor is found.<\/p>\n
The stratosphere is the next layer up, extending from the top of the troposphere to an average height of about 50 kilometers (31 miles). It is much drier than the troposphere, and the air is much thinner. The stratosphere is where the ozone layer is found, which absorbs harmful ultraviolet radiation from the sun.<\/p>\n
The mesosphere is the third layer up, extending from the top of the stratosphere to an average height of about 85 kilometers (53 miles). It is the coldest layer of Earth’s atmosphere, with temperatures reaching as low as -140 degrees Celsius (-220 degrees Fahrenheit).<\/p>\n
The thermosphere is the fourth layer up, extending from the top of the mesosphere to an average height of about 600 kilometers (373 miles). It is the hottest layer of Earth’s atmosphere, with temperatures reaching as high as 2,000 degrees Celsius (3,632 degrees Fahrenheit).<\/p>\n
The exosphere is the outermost layer of Earth’s atmosphere, extending from the top of the thermosphere to an average height of about 10,000 kilometers (6,214 miles). It is very thin, and the air is very sparse. The exosphere is where most of Earth’s satellites orbit.<\/p>\n","protected":false},"excerpt":{"rendered":"
