Question

what will the long term effect of mass wasting be on oversteepened slopes? question 3 options: a) it will cause the steep slopes to retreat uniformly, widening the valley but keeping the steep slopes at the margins. b) it will perpetuate catastrophic mass failures until the entire highland region is removed c) it will fill in the lowland up to the level of the surrounding highland region. d) it will eventually restore an equilibrium profile by reducing the slope angle.

Answer 1

The long term effect of mass wasting on oversteepened slopes is that it will eventually restore an equilibrium profile by reducing the slope angle.

Step-by-step explanation:

The long term effect of mass wasting on oversteepened slopes is that it will eventually restore an equilibrium profile by reducing the slope angle. Mass wasting refers to the downslope movement of rock, soil, and debris due to gravity. Oversteepened slopes are more prone to mass wasting because the force of gravity exceeds the internal strength of the slope materials. As a result, the slope angle will gradually decrease over time as the materials erode and move downslope, eventually reaching a stable slope.

Answer 2

d) it will eventually restore an equilibrium profile by reducing the slope angle.

Step-by-step explanation:

Mass wasting refers to the downslope movement of rock, soil, and debris under the influence of gravity. When slopes become oversteepened, they are more prone to mass wasting events. Over time, the repeated occurrences of mass wasting on oversteepened slopes will lead to the restoration of an equilibrium profile.

During mass wasting events, material is displaced from the steep slopes and transported downslope. This process gradually reduces the slope angle, making the slope less steep and more stable. As material is removed from the upper portions of the slope, the slope angle decreases, and the overall profile of the slope becomes less pronounced.

While mass wasting events can cause localized erosion and deposition, leading to changes in the immediate area, the long-term effect is the gradual reduction of slope angle towards a stable state. It is important to note that the restoration of an equilibrium profile can take a considerable amount of time and is influenced by various factors such as climate, geology, and vegetation cover.
