What are three ways polar regions and deserts are alike?

Polar regions and deserts both experience extreme conditions that limit life, making them some of the most inhospitable environments on Earth. Both areas receive very low annual precipitation, leading to arid conditions; in polar regions, this takes the form of snow, while deserts may be sandy or rocky. Additionally, both environments have temperature extremes, with polar regions experiencing severe cold and deserts often facing intense heat. Finally, both regions have adapted flora and fauna that have evolved unique survival strategies to thrive in these harsh climates.
