What is the name of the lowest atmospheric layer?

The Troposphere
The Troposphere This is the lowest part of the atmosphere – the part we live in. It contains most of our weather – clouds, rain, snow. In this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometre.

What are the layers of the atmosphere highest to lowest?

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

What are the lowest two layers of the atmosphere?

troposphere
Most of the important processes of the atmosphere take place in the lowest two layers: the troposphere and the stratosphere.

What are the 9 layers of the atmosphere?

Earth’s atmosphere has a series of layers, each with its own specific traits. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere. The exosphere gradually fades away into the realm of interplanetary space.

What is the lowest level of the Earths atmosphere called?

The troposphere is the lowest layer of Earth’s atmosphere. It extends from Earth’s surface to an average height of about 12 km (7.5 mi; 39,000 ft), although this altitude varies from about 9 km (5.6 mi; 30,000 ft) at the geographic poles to 17 km (11 mi; 56,000 ft) at the Equator , [19] with some variation due to weather.

What is the lowest part of the atmosphere?

Which layer of the atmosphere has the greatest density?

Of all the atmospheric layers, the troposphere has the a. highest temperatures. Of all the atmospheric layers, the troposphere has the highest density.

What atmospheric layer has the lowest pressure?

The troposphere is the lowest layer of our atmosphere with highest pressure. It extends upward to about 10 km above sea level. Air pressure drops, moving higher in the troposphere.
