What are the hottest and coldest layers of the atmosphere?

What are the hottest and coldest layers of the atmosphere?

Coldest layer of Earth’s atmosphere is the MESOSPHERE. The temperature there is -90 degree celsius. It can even go lower. Hottest layer of Earth’s atmosphere is the thermosphere.

Which layer of the earth’s surface is the hottest?

The core is the hottest, densest part of the Earth. Although the inner core is mostly NiFe, the iron catastrophe also drove heavy siderophile elements to the center of the Earth.

What is the hottest atmosphere layer and how hot is it?

Temperatures range between 1000 and 4500 degrees Fahrenheit. The thermosphere is a layer high in the atmosphere known for extremely high temperatures and extremely low density.

What is the hottest thickest layer of the atmosphere?

The thickest layer in the atmosphere is the thermosphere starting at about 80 km going upwards. This is where the UV radiation from the sun turns to heat causing the air to be very hot. It can reach temperatures up to 1500 degrees Celsius or more.

What is the 2nd coldest layer of the atmosphere?

The mesosphere is a layer within the Earth’s atmosphere that extends from about 50 kilometres height (above the stratosphere) and about 90 kilometres (below the thermosphere).

Which is the thinnest layer of atmosphere?

Answer: thermosphere is the thinnest layer of the atmosphere.

What is the thinnest layer of the Earth?

Inner core
*Inner core It is the thinnest layer of the Earth. *The crust is 5-35km thick beneath the land and 1-8km thick beneath the oceans.

How old is the Earth?

4.543 billion years

Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.

What layer in the atmosphere has the lowest temperature?

Troposphere . Temperature: 62°F (17°C) around the lowest point to -60°F (-51°C) near the top. The troposphere is the lowest layer of the atmosphere, and it is where we live. It extends up to 5 to 10 miles (8 to 15 km) above the surface. It is the densest layer, containing more than half the volume of total air.

Why troposphere is the hotest part of the atmosphere?

Troposphere is the hottest part of the atmosphere because. 1) it is closest to the sun . 2) heat is generated in it . 3) it is heated by the Earth’s surface. 4) there are charged articles in it.

What is the warmest layer of the atmosphere?

Quick Answer. The thermosphere is the hottest layer of the atmosphere. It extends from 80 kilometers above the surface of the Earth up to 600 kilometers and can heat up to 1,500 degrees Celsius because it’s very sensitive to solar activity.

Which layer of the atmosphere has the highest air pressure?

The troposphere has the greatest air pressure because it is the layer that is closest to Earth and air pressure is greatest near the surface of the Earth.
