in the tundra, life forms are limited by the interaction of several of earths spheres. one sphere that interacts with the geosphere, hyrosphere and biosphere is the cyrosphere. what is this sphere responsible for in the tundra?
The cryosphere is responsible for the presence of ground permafrost in the tundra. Permafrost refers to a layer of soil or rock that remains frozen for at least two consecutive years. This frozen ground affects the other spheres in the tundra ecosystem. It influences the geosphere by creating a layer of frozen soil, making it difficult for plants to establish deep root systems. The permafrost also interacts with the hydrosphere, as it prevents water from draining properly and creates wetland habitats in the tundra. Lastly, the cryosphere impacts the biosphere by limiting plant growth and affecting the distribution and behavior of animals in the tundra.
