How do humans impact the geosphere?

More regularly, however, human interaction with the dynamic geosphere comes in the form of surface erosion, our use of arable land for farming, and excavations for the construction of buildings, roads, and mines.

How is the geosphere affected by climate change?

The geosphere impacts Earth’s climate in a variety of ways. Typically, the geosphere reacts on geologic timescales, affecting climate slowly and over millions of years. However, the burning of fossil fuels over the last 150 years has sped the impact of the geosphere on climate.

Does ice affect climate?

While sea ice exists primarily in the polar regions, it influences the global climate. The bright surface of sea ice reflects a lot of sunlight out into the atmosphere and, importantly, back into space. More solar energy is absorbed at the surface and ocean temperatures rise. This begins a cycle of warming and melting.
