What controls mass wasting events gravity?

long before mass wasting occurs, various processes weaken the slope, making it more susceptible to gravity what is a trigger? the event initiating a mass weathering event what controls mass wasting events gravity!!! 1. water 2. oversteepened slopes 3. removal of vegetation 4. earthquakes factors playing a role in mass wasting slick and weight

What does the occurrence of a mass wasting event depend upon?

The runout of a mass wasting event depends on the volume of material, water content, and slope steepness.

Which of the following is a contributing factor that can trigger a mass wasting event?

Mass-wasting events are triggered by changes that oversteepen slope angles and weaken slope stability, such as rapid snow melt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, stream erosion, and human activities. Excessive precipitation is the most common trigger.

What causes mass wasting?

It can be triggered by natural events like earthquakes, volcanic eruptions and flooding, but gravity is its driving force. Although gravity is the driving force of mass wasting, it is impacted mainly by the slope material's strength and cohesiveness as well as the amount of friction acting on the material.

Which of the following factors is important for mass wasting?

Gravity is probably the ultimate driving force of mass wasting. The force of gravity pulls all things on the planet toward the center of the Earth. Without gravity, mass wasting would not occur. But unlike many of the other factors, humans have no influence or control on gravity.

What is mass wasting?

Mass wasting is a type of erosion, and it is capable of making big changes to the side of a mountain. These changes can happen suddenly, as in one minute the rock is there and the next it is gone, or it can happen more slowly over time.

What happens when a wave comes ashore and washes away a sandcastle?

This is similar to what happens when a wave comes ashore and washes away a sandcastle. The abundant water breaks apart the small sand particles and destroys the structural stability of the castle you spent the afternoon building. If an area has decreased vegetation, it will be more prone to mass wasting.

What is the term for the sliding of rock material down a mountain?

Without the base, the outer sections of the mountain slumps down as a unit or multiple units. A rockslide is another example of mass wasting of a slope. A rockslide is the sliding of rock material down a mountain. It is similar to a slump, but a rockslide does not move along a curved surface like a slump.

What forces pull rocks and debris down the slope of a mountain?

Gravity is constantly trying to pull rock and debris down the slope of a mountain. At the same time, the resistive forces of the mountain, including the cohesive strength and internal friction between the materials, referred to as the mountain's shear strength, constantly pulls back against gravity.

What is debris flow?

A debris flow is the movement of a water-laden mass of loose mud, sand, soil, rock and debris down a slope. Some debris flows move slowly while others can pick up momentum on steep slopes and reach speeds of 100 miles per hour or greater, sweeping away anything in their path, including trees, bridges, houses or roads.

Does steepness increase mass wasting?

For instance, an increased slope steepness increases mass wasting simply because the gravitational force acting on a steep slope is greater than the force acting on a gentle slope. Increasing the steepness of a slope is one way man can increase mass wasting.
