Glacier action - SS1 Geography Past Questions and Answers - page 2

Glaciers form from the accumulation of snow over time, which compacts into ice. They move because of their tremendous weight, slowly flowing downhill under the force of gravity.

Erratic rocks are significant because they provide evidence of past glaciation events. These rocks are often different from the local geology, showing that glaciers transported them from afar, helping geologists understand the history of glaciations.

Glacier features release freshwater as they melt, which feeds into rivers and streams. This meltwater is crucial for providing a steady source of freshwater in mountainous areas, benefiting ecosystems and human communities.

Scientific research on glacier features helps track changes in their size and behavior. By studying these changes, scientists can gain insights into the effects of climate change, such as glacier retreat, and understand its impact on the environment.

Communities can benefit from tourism by offering accommodations, food services, guided tours, and recreational activities related to glacier features. This can boost the local economy, create jobs, and improve infrastructure in the region.
