Question

list the differences and similarities between polar and arid habitats​

Answer 1

Answer:

Deserts cover more than one-fifth of the world's land.  A Desert is any region that has less than 2.5 cm (10 inches) of rain or snow  every year. Not all deserts are sandy. The polar regions are also called deserts because they have very little rain or snowfall. The world’s driest desert is the high Atacama plain in Chile. It is a bleak, rocky desert,  which is so dry that virtually no animals or plants can survive there. The Atacama desert has been used by scientists to test robot rovers for exploring planets like Mars

Explanation:

FIRST YOU NEED TO KNOW THIS:A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one-third of the land surface of the world is arid or semi-arid.
