Glacial Formations and Their Impact on the Environment

How do glacial formations impact the environment?

A. By increasing methane degradation

B. By enhancing photosynthesis

C. By promoting photolysis

D. By weathering of rocks

The answer is D. Weathering of rocks.

Glacial formations have a significant impact on the environment, particularly through the process of weathering rocks. As glaciers move, they exert pressure on rocks beneath them, leading to the gradual breakdown of the rocks through abrasion and plucking. This physical weathering contributes to the formation of new rock formations and the release of minerals into the surrounding environment.

The other options (methane degradation, photosynthesis, and photolysis) are not directly related to glacial formations. While glaciers can indirectly influence these processes through their effects on temperature and landscape, the primary environmental impact of glacial formations is seen in the weathering of rocks.
