Question

Short note on “landslides”(100 words)

Answer 1

Explanation:

A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows. These are further subdivided by the type of geologic material (bedrock, debris, or earth). Debris flows (commonly referred to as mudflows or mudslides) and rock falls are examples of common landslide types.

Answer 2

Answer:

• A landslide is described because of the movement of a mass of rock, debris, or earth down a slope. Landslides are a form of "mass wasting," which denotes any down-slope movement of soil and rock below the direct effect of gravity.
• The term "landslide" encompasses 5 modes of slope movement: falls, topples, slides, spreads, and flows. These are similarly subdivided via way of means of the form of geologic material (bedrock, debris, or earth).
• Debris flows (generally known as mudflows or mudslides) and rock falls are examples of not unusual place landslide types.

• Almost every landslide has more than one cause. Slope movement takes place while forces performing down-slope (especially because of gravity) exceed the energy of the earth substances that compose the slope.
• Causes encompass elements that boom the outcomes of down-slope forces and elements that contribute to low or decreased energy. Landslides may be initiated in slopes already on the verge of motion via way of means of rainfall, snowmelt, modifications in water level, move erosion, modifications in floor water, earthquakes, volcanic activity, disturbance via way of means of human activities, or any aggregate of those elements.

• Earthquake shaking and different elements also can induce landslides underwater. These landslides are referred to as submarine landslides. Submarine landslides from time to time reason tsunamis that harm coastal areas.
