As air gets colder it contracts. While the total amount of air is about the same in any column of the troposphere, at the cold poles that column takes up less space, resulting in a shorter distance to the top of the troposphere.

Where is the troposphere thinnest?

The troposphere is thinnest at the poles, where it is about 8 kilometers thick, compared to about 16 kilometers at the equator. This is due to the lower temperature at the poles, which causes the air to be more compact and the layers to be thinner.


What causes the temperature decreasing with height in the troposphere?

The air is thinner


Is the atmosphere thinner at the poles than at the equator?

Yes, the atmosphere is generally thinner at the poles compared to the equator. This is because the Earth's rotation causes the atmosphere to bulge outward at the equator, resulting in higher pressure and greater atmospheric density. Conversely, the poles experience lower pressure and thinner air due to the Earth's shape and the angle of sunlight.


What is the altitude of the bottom and the top of the troposphere?

The altitude of the bottom of the troposphere is around 8 kilometers (5 miles) at the poles and 18 kilometers (11 miles) at the equator. The altitude of the top of the troposphere is approximately 12 kilometers (7 miles) at the poles and 20 kilometers (12 miles) at the equator.


What is the thickness of troposphere and mesosphere?

The troposphere can vary in thickness from about 8 km at the poles to 16 km at the equator. The mesosphere is typically around 50 km thick.


How many miles is the troposphere from earth?

The troposphere extends about 7 miles (11 kilometers) above Earth's surface at the poles and about 12 miles (19 kilometers) at the equator.


What altitude in kilometers does the troposphere end?

The height from the poles are 0km to 12km theres where the stratosphere starts evryone nows that..... do they?


What is the distance from the earths ground level to the troposphere?

the distance of the troposphere from the Earth is about 17km from the equator and 5-6km from the poles


What forces the temperature to increase with the altitude in the troposphere?

The temperature increases with altitude in the troposphere because of the absorption of solar radiation by the Earth's surface, which heats up the air closer to the surface. As you move higher in the troposphere, the air becomes thinner and less able to retain this heat, causing a decrease in temperature.


How many miles does the troposphere extend up from the ground?

The troposphere extends up to about 7 miles (11 kilometers) from the Earth's surface at the poles and up to about 10 miles (16 kilometers) at the equator.


Is the tropopause the highest at the north and south pole?

No, the tropopause is actually highest near the equator and lowest near the poles. This is because the tropopause is defined as the boundary between the troposphere and the stratosphere, and the troposphere is thicker at the equator due to the Earth's rotation and warmer temperatures.


How high up does the troposphere go?

The troposphere, which is the lowest layer of the atmosphere, extends from the surface of the Earth up to a height that varies between about 9 km (or 30,000 ft) at the poles and 17 km (or 56,000 ft) at the equator.
