What is a potential outcome of a glacier retreating?

• A. Formation of new lakes and rivers
• B. Increase in global temperatures
• C. Coastal erosion
• D. Expansion of desert areas

Answer: (A)

The correct choice highlights how the retreat of glaciers can lead to the formation of new lakes and rivers. As glaciers melt, the water that was previously stored in the solid ice is released, contributing to the filling of depressions in the landscape and creating bodies of water. This process can also alter the flow of existing waterways and lead to the development of new river systems as the topography changes.

In regions where glaciers have retreated, the newly created lakes can provide habitats for various species and opportunities for recreational activities, while also impacting local ecosystems and water availability for communities. Consequently, the retreat of glaciers directly contributes to geomorphological changes in the landscape that result in increased surface water features.
