A tundra has a lot of precipitation and a desert has little.
A tundra has few trees and plants and deserts have many.
A tundra has soil that is often sandy and a desert has grass.
A tundra is dry and cold and a desert is dry and hot.
I’m pretty sure it’s D, bc I searched and said this “tundra is an extremely cold biome consisting of snow-covered lands while a desert is an extremely dry and hot biome consisting of sandy lands.” Ur choice.
