Question

What is the thinnest and coldest layer of the earth?

Answer 1

The Crust is the thinnest layer of the Earth.

The Mesosphere is the coldest layer of the Earth.

Explanation:

• The Crust is the thinnest layer of the Earth. This layer of the earth occupies only 1% of the total volume of the earth. This layer is the thinnest because it is made of incompatible matters that do not mix well with other matters found in the crust of the Earth.
• The Mesosphere is the coldest layer of the Earth. It is located about 50-80 km from the surface of the Earth. The average temperature of the Mesosphere is about minus 85 degrees Celsius. It also gets colder with more altitude. Due to this, the mesosphere is inhabitable for humans.

Answer 2

Thinnest Layer ⇒ Crust

Coldest Layer ⇒ Mesosphere
