In the tundra, life forms are limited by the interaction of several of Earth's spheres. One sphere that interacts with both the geosphere, hydrosphere, and biosphere is the cryosphere. What is this sphere responsible for in the tundra?
A) poor, rocky soil
B) low growing plants
C) ground permafrost
D) mountainous terrain
Yes, I am sure. The cryosphere refers to the frozen water on Earth, including ice sheets, glaciers, snow, and permafrost. In the tundra, the cryosphere is responsible for the presence of ground permafrost, which is a layer of permanently frozen soil. This frozen soil affects the availability of water and nutrients for plants and contributes to the unique characteristics of the tundra biome.
