The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth’s Atmosphere, as it is the layer that we live in and the layer that gives us weather. This is the reason why troposphere is important for human beings.

The troposphere is by far the wettest layer of the atmosphere; all of the layers above contain very little moisture. The bottom of the troposphere is at Earth’s surface. The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level.

The troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks, the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun’s harmful UV radiation.

The troposphere provides oxygen that we can breathe, keeps Earth at a livable temperature, and allows for weather to occur, making it a very important part of the atmosphere.

MEMPHIS, TN (WMC) -The troposphere is the lowest layer of Earth’s atmosphere and the site of all-weather on Earth. Water vapor it important as it will absorb solar energy and thermal radiation from the surface of Earth, thus regulating the air temperature.

As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F (17°C) to -60°F (-51°C) at the tropopause.

At top of stratosphere, 30 miles high, ozone absorbs most of the harmful ultraviolet radiation from the Sun. At the top of the troposphere, 12 miles high, ozone acts as a greenhouse gas, trapping heat.

Temperature varies with altitude, as follows: In the troposphere, temperature decreases as altitude increases. In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer.

tropopause: about 12-18 km about –60 stratopause: about 46-54 km about –2 to 0 mesopause: about 85-90 km about –90 4. The temperature increases in the stratosphere due to ozone layer capturing ultraviolet radiation. The temperature decreases in the mesosphere since there is no ozone and the amount of air is decreasing.

The tropopause can be defined in terms of physical parameters. The tropopause can exist anywhere between 70 hPa (≈18 km) and 400 hPa (≈6 km), and it is therefore not convenient to use a constant pressure level to describe the tropopause.

The average height of the troposphere is 18 km (11 mi; 59,000 ft) in the tropics, 17 km (11 mi; 56,000 ft) in the middle latitudes, and 6 km (3.7 mi; 20,000 ft) in the polar regions in winter. The total average height of the troposphere is 13 km (8.1 mi; 43,000 ft).
