The troposphere is the lowest layer of the earth's atmosphere and is the one that contains weather and which can support life. Its upper limit is the highest point that the suns heat can cause warm and moist air to reach. This means that the troposphere extends to a much higher altitude in the tropics than near the cooler poles - between 15km (9 miles) to 8km (5 miles). Atmospheric pressure varies from around 1000 kpa (14 pounds per square inch, PSI) at sea level down to about 200 kpa (3psi) at about 10km.

What layer is the atmosphere pressure highest?

The troposphere is the layer of the earth's atmosphere with the highest air pressure.


In which layer of the earth does the greatest atmospheric pressure occur?

The greatest atmospheric pressure occurs in the troposphere, which is the lowest layer of the Earth's atmosphere. The pressure decreases rapidly with height in the troposphere, and it is where weather events and phenomenon like clouds, rain, and storms take place.


What gases are found in the atmosphere what gases are found in the troposphere?

About 90% of the atmospheric mass is in the troposphere. You can tell because 90% of the pressure increase occurs in the troposphere. Pressure goes from zero in space to 100 mb at the tropopause to 1000 mb at the surface.


Which atmospheric layer is closest to the earths crust?

The atmospheric layer closest to the Earth's crust is the troposphere. It is where we live and where most weather phenomena occur.


In which layer is the pressuer the highest?

The troposphere is the layer of the earth's atmosphere with the highest air pressure. This is because the troposphere is the layer closest to the Earth's surface. As a result, the air is quite dense in the troposphere. As pressure is directly proportional to density, it means that the atmospheric pressure would be greatest in the troposphere.

Which atmosphere is 10 km from earth?

The atmosphere that is 10 km from Earth's surface is the upper part of the troposphere. This region is known as the tropopause, which is the boundary between the troposphere and the stratosphere. At this altitude, the temperature is typically much colder and atmospheric pressure decreases.


What is the atmospheric layer closest to earth?

It is the troposphere


Where does the greatest atmospheric pressure occur?

It occurs in the Troposphere because it is closer to earth so the air results in being more thicker and compressed


Which atmospheric layer is dense?

The troposphere is the closest to the Earth and most dense atmospheric layer
