What is the hottest and coldest layer of the atmosphere?

What is the hottest and coldest layer of the atmosphere?

The MESOSPHERE is the coldest layer and the THERMOSPHERE is the hottest layer in the atmosphere.

What are the four layers of the atmosphere in order?

In order from lowest to highest, the following are the four major layers of the atmosphere: In order from lowest to highest, the following are the four major layers of the atmosphere: the troposphere, stratosphere, mesosphere, and thermosphere.

What determines the layers of the atmosphere?

The atmosphere has five different layers that are determined by the changes in temperature that happen with increasing altitude . Troposphere Living at the surface of the Earth, we are usually only aware of the events happening in the lowest layer, the troposphere, where all weather occurs.

What is the hottest part of the atmosphere?

The thermosphere is the hottest layer of the atmosphere. It extends from 80 kilometers above Earths surface up to 600 kilometers.

What is the highest layer of the atmosphere?

The exosphere is the highest layer of the atmosphere. It extends up to 10,000 km (6,200 miles; 33,000,000 ft.) above the Earth. Satellites orbit the Earth in the exosphere. The atmosphere in this layer is extremely thin and atoms and molecules of air are constantly escaping into outer space.

What is the farthest atmosphere layer?

The thermosphere is the broadest layer of the atmosphere, with a temperature that can reach thousands of degrees Celsius , is full of materials charged with the energy of the sun. The exosphere is the furthest layer of the earth’s surface. This extends from 600-800 km to 9,000-10,000.

What is the lower atmosphere?

lower atmosphere. [′lō·ər ′at·mə‚sfir] (meteorology) That part of the atmosphere in which most weather phenomena occur (that is, the troposphere and lower stratosphere); in other contexts, the term implies the lower troposphere.

What is above the stratosphere?

The stratosphere is a layer of Earth’s atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.

What is the temperature range of the atmosphere?

The thermosphere is typically about 200° C (360° F) hotter in the daytime than at night, and roughly 500° C (900° F) hotter when the Sun is very active than at other times. Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher.
