Answer:

The Earth's atmosphere is considered to be 100km thick.

Explanation:

It is almost impossible to give an exact value for the thickness of the Earth's atmosphere, or the atmosphere of any planet. The reason for this is as you increase in altitude the atmosphere gets progressively thinner.

It is generally accepted that outer space starts at an altitude of #100 km#. Hence the value of #100km# for the thickness of the atmosphere.
