Hillslope

Options:

1. Due to under-loaded surface runoff
2. Due to less volume and velocity of surface runoff
3. Due to the presence of debris carried by surface runoff
4. None of the above

Correct Answer

Options:

1. Because surface runoff carries more debris
2. Because surface runoff carries less debris
3. Because the slope angle is steeper at the hill-top
4. None of the above

Correct Answer

Options:

1. Zone of erosion and zone of deposition
2. Zone of erosion and zone of aggradation
3. Zone of weathering and zone of erosion
4. None of the above

Correct Answer

Options:

1. It decreases
2. It remains constant
3. It increases
4. None of the above

Correct Answer

Options:

1. Due to increased volume of runoff
2. Due to decreased velocity of runoff
3. Due to the presence of more debris downslope
4. None of the above

Correct Answer

Options:

1. Deposition of debris
2. Active erosion mainly by rill and gully erosion at the slope base
3. Soil creep and rainwash
4. Local conditions determine if it is depositional or erosional

Correct Answer

Options:

1. Only one denudational process operates on a slope profile
2. Different denudational processes operate together on a slope profile
3. Denudational processes operate in opposite directions on a slope profile
4. There is no relation between slope profile and denudational processes

Correct Answer

Options:

1. Deposition of debris
2. Soil creep and rainwash
3. Fluvial erosion
4. None of the above

Correct Answer

Options:

1. Soil creep
2. Rainwash
3. Fluvial erosion
4. Deposition of debris

Correct Answer

Options:

1. Soil creep and rainwash operate independently on different segments of the hillslope
2. Soil creep and rainwash are agents of transportation of debris
3. Soil creep and rainwash are not slope forming processes
4. Soil creep and rainwash operate together on hillslope

Correct Answer

Options:

1. There is progressive increase in slope angle from youth to old stages.
2. There is no change in slope angle but the slope form changes from youth to old stages.
3. There is progressive decline in slope angle and sequential change in slope form from youth to old stages.
4. There is no change in slope angle or slope form from youth to old stages.

Correct Answer

Options:

1. Active downcutting and valley deepening during the youth stage.
2. Continued lateral erosion and downwasting of water divides during the mature and old stages.
3. Soil creep and alternate dilation and contraction of soil under the influence of gravity during all stages.
4. Weathering and erosion by wind and water during all stages.

Correct Answer

Options:

1. In slope replacement, the maximum angle decreases and the concavity becomes segmented, while in parallel retreat, the maximum angle remains constant and the concavity increases in length.
2. In slope replacement, the maximum angle remains constant and the concavity becomes smoothly curved, while in parallel retreat, the maximum angle decreases and the concavity becomes segmente
3. In slope replacement, the maximum angle decreases and the concavity becomes smoothly curved, while in parallel retreat, the maximum angle remains constant and the concavity increases in length.
4. There is no difference between slope replacement and parallel retreat in terms of the maximum angle and concavity of the slope.
