Hillslope

Options:

1. It is the downward inclination of the surface between hills and valleys.
2. It is the upward inclination of the surface between hills and valleys.
3. It is the surface between hills and valleys.
4. It is the study of the physical landscapes.

Correct Answer

Options:

1. Geological structure, climate, vegetation cover, drainage texture and frequency, and denudational processes.
2. Erosion and transportation of eroded materials downslope.
3. Mass wasting and mass movements of rock wastes.
4. All of the above.

Correct Answer

Options:

1. Because slopes are the result of combinations of denudational processes.
2. Because slopes provide water and sediment to streams.
3. Because slopes introduce variations and complexity in the landscapes.
4. All of the above.

Correct Answer

Options:

Correct Answer

Options:

1. It involves the interpretation of different aspects of hillslope and valley side slope development based on field observation.
2. It involves the development of theories and models to explain the slope morphology, erosion and sedimentation processes, and landscape evolution.
