At what height troposphere does the temperature decrease?

At what height troposphere does the temperature decrease?

The troposphere is the layer next to Earth’s surface. On the average, it extends 11 km to the top of the troposphere which is called the tropopause. In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere’s gases absorb very little of the incoming solar radiation.

What is the troposphere temperature?

The global average temperature at the surface is 59 degrees F (15 degrees C) but decreases to around minus 82 degrees F (minus 63 degrees C) at the top of the troposphere. On the basis of mean tropospheric depth, the average rate of temperature decrease is 3.6 degrees F per 1,000 ft.

What is the average height of troposphere Class 7?

1. Troposphere: It is the lowest layer of the Earth’s surface that extends to a height of 8 km at the poles and 18 km at the Equator. This layer is characterised with weather phenomenon like cloud formation, thunderstorms, rainfall and snowfall. Here, temperature decreases with the increase in height.

How does temperature change with altitude in the stratosphere?

The stratosphere is stratified (layered) in temperature, with warmer layers higher and cooler layers closer to the Earth; this increase of temperature with altitude is a result of the absorption of the Sun’s ultraviolet radiation by the ozone layer. This is in contrast to the troposphere, near the Earth’s surface,… Oct 26 2019

What is the highest temperature in troposphere?

Because of this absorption, the temperature increases with height. From as low as -184°F (-120°C) at the bottom of this layer, temperatures can reach as high as 3,600°F (2,000°C) near the top. However, despite the high temperature, this layer of the atmosphere would still feel very cold to our skin due to the very thin atmosphere.

How far up is the top of the troposphere?

The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer).

Is the troposphere the warmest layer of the atmosphere?

The lower altitudes are the warmest part of the troposphere, in part because the earth’s surface absorbs solar radiation and transfers this heat to the air. Generally, as altitude increases, temperature decreases steadily.
