Briefly describe three aspects of geology that are especially important to our existence.

Volcanism

Plate tectonics

Magnetic field

Explanation:

It is believed that volcanism releases some gases which were formerly a part of the atmosphere and it helped in the survival of man and other animals during that period in time.

Plate tectonics is also thought to be responsible for the provision of climate stability which prevented worse cases or volume of extinction as a result of the unfavorable conditions.

It was also concluded that magnetic field helped to shield against solar winds which would have blown most organisms away into space
