Questions and Answers

Explain the factors that can cause variations in the speed of infiltration in the hydrological cycle.

Variations in the speed of infiltration can be caused by factors such as soil type, slope gradient, vegetation cover, and the presence of impervious surfaces.

Describe the formation of v-shaped valleys, interlocking spurs, and waterfalls in a river's course.

V-shaped valleys, interlocking spurs, and waterfalls are formed through the erosional processes of river flow and gravity, as well as the resistance of the underlying rock formations.

Provide a case study illustrating the reasons for rising water demand and how it can be managed.

A case study could focus on a region experiencing population growth, urbanization, and changing consumption patterns, and discuss measures such as water conservation, efficiency improvements, and sustainable resource management to address the rising water demand.
