Because of the temperature of the air. There's about the same amount of air over the earth, pressing down and generating roughly the same amount of pressure. But the difference is that because cold air is more dense than hot air, the same amount of cold air will compress much more than that of hot air. Therefore, the height of the troposphere over the poles can be less than half what it is at the equator, with the same amount of air.
What else can I help you with?
What is the lowermost layer of the Earth's atmosphere?
The lowermost layer of Earth's atmosphere is the troposphere. It is where most of the Earth's weather occurs, and its height can vary from 5 to 9 miles (8 to 14.5 kilometers) above the Earth's surface.
What layer of the atmosphere is closest to earth?
The Troposphere is nearest and extends from the surface of the earth to approximately 10 thousand metres above the surface. This explains why the air is described as being 'thin' when at the top of some of the highest mountains of the World.Hope this helps.
How might the atmosphere be classified?
The atmosphere can be classified based on its temperature profile into distinct layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These layers vary in temperature, composition, and characteristics, with the troposphere being the layer closest to Earth's surface and the exosphere merging into outer space.
What are the 5 different atmospheres of earth?
The five different layers of Earth's atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These layers vary in temperature, composition, and altitude, with the troposphere being the lowest layer where most weather occurs and the exosphere being the outermost layer where the atmosphere gradually transitions into space.
What is the volume of the troposphere?
The troposhere is about 7 miles high. Different articles mention different numbers, but it generally comes down to a difference in latitude. It ranges between an altitude of 8-18 kilometres. It is higher near the equator and lower near the poles.
What is the lowermost layer of the Earth's atmosphere?
The lowermost layer of Earth's atmosphere is the troposphere. It is where most of the Earth's weather occurs, and its height can vary from 5 to 9 miles (8 to 14.5 kilometers) above the Earth's surface.
What is the temperature in degrees Celsius of the troposphere?
The temperature in the troposphere can vary depending on factors such as altitude and location, but on average it decreases by about 6.5 degrees Celsius per kilometer of altitude. Near the Earth's surface, the average temperature of the troposphere is around 15 degrees Celsius.

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.

What is the approximate height and tempertaure of the tropause?
The height of the tropopause typically ranges from 8 to 18 kilometers above the Earth's surface. The temperature at the tropopause is around -60 degrees Celsius on average, but this can vary depending on the location and season.
What is the height of space lab in orbit?
About 350 kilometres (220 mi) above the surface of the Earth.
Does earth speed around sun vary?
no
What is the typical height of a bookshelf?
The typical height of a bookshelf is around 6 feet, but they can vary in size depending on the design and purpose.

What is the height of a banana?
The average is probably about 9 inches or around 20 cm but they can vary
