Question

Q. 5. Answer the following questions in brief:
(1) Describe the changes that take place in the temperatures from the surface of the earth to its center​

Answer 1

Answer: The Temperature increases rapidly when going from the earth's surface (crust) to the centre of the earth (Inner core). The temp. on the surface if moderate, but as you go deeper and deeper to mantle the outer core and then the Inner core, the temoerature there is so hot that it is unbearable.

Explanation:

Answer 2

Answer:

The centre of the earth its located at a distance of 6371 kilometre from its surface.From the surface to the centre, certain changes occur in the interior of the earth. Therefore the temperature will be increasing.

Explanation:

(1)The process of cooling of the earth starts from the surface . In the interior of the earth temperature is higher . Hence the temperature rise towards the core .This increase in the temperature generally take place at the rate of 1 Celsius per 32 kilometre of the depth. This means that though the surface is cool,the core is very hot.The temperature at the centre of the earth is estimated to be 5000 degree Celsius.
