As you know Mass Wasting is also known as Mass Movement or Slope Failure and this is directly related to the slope and gravity. It has the power to change the total geomorphology (map) of an area and region, overnight.
Do you know its causes, how it occurs? What factors help it to let this occur?
Here are 9 main reasons and factors of mass wasting:
It is the main basic factor of mass wasting. Earth has gravity power, which attracts everything towards the lower elevation (ground). This power of earth also applies here. It keeps trying to attract rocks, soil, regolith, rock debris, and others towards the lower elevation or lower case, which results in mass wasting.
There is a direct relation between slope and mass wasting. Higher the steepness of slope leads to higher intensity of mass wasting.
For example, that is why steep cuts around mountains and steep slope of mountains had higher intensity of mass wasting in the form of landslides, debris flow, etc.
Whenever higher lands, slopes, mountain areas, etc. absorb more water, due to rain, it loses their grip with their sand grains or soil land base, leads to mass wasting in the form of mudflow.
Running water like rain and river, also helpful in mass wasting.
Weathering plays an important role in the breakdown of big rocks into smaller pieces and loosen them, which is later eroded by or tumbled down through the Mass Wasting process.
Anything which is overloaded has nature to collapse, in the lack of balancing or instability, leads to mass wasting.
Vegetation works as the natural binder on soil particles and on the mountain slope.
Shaking of earth results in mass wasting.
Volcano flanks can become over steep resulting in instability and mass wasting.
This is a process in which plants have grown into the cracks of rocks and slowly as they grow, their roots also have grown and increase these cracks, which leads to mass wasting.
For example, do you ever saw a peepal tree, which grows on the terrace of your home, or in any cracks of the wall, or any demolished building? (very common at the places where the interference of human being is very rare).
It could crack the whole house as it grows, just like plant roots wedging in mountain rocks leads to the breakdown of big rocks into smaller ones and later eroded.
