Question 10

Water becomes a part of surface water during the runoff process.

When heavy rain produces runoff, the water typically flows over the land and collects in bodies of water like rivers, lakes, and streams, which are classified as surface water.

A) Ground water

Ground water refers to water that is stored beneath the earth's surface in soil pores and rock formations. While some rainwater can infiltrate the ground and contribute to groundwater, the question specifically addresses the runoff process, which primarily results in surface water rather than groundwater.

B) Atmosphere

The atmosphere is the layer of gases surrounding the earth. Although water can evaporate into the atmosphere, during the runoff process, the water does not become part of the atmosphere; it flows into surface bodies of water instead.

C) Surface water

Surface water is the correct answer, as it encompasses all water that collects on the Earth's surface, including rivers, lakes, and reservoirs. During runoff, the excess rainwater flows into these bodies, making it a key component of surface water.

D) Glaciers

Glaciers are large masses of ice formed from compacted snow over many years. While runoff can contribute to the formation of glaciers in certain contexts, it does not directly transform into glaciers during the runoff process; thus, this option is incorrect in the context of immediate runoff.

Conclusion

The runoff process from heavy rain primarily contributes to surface water, making option C the definitive correct answer. The other options—ground water, atmosphere, and glaciers—do not accurately reflect the immediate outcome of runoff, which is the accumulation of water in surface bodies.
