how human activities can directly contribute to landslides?

Yes, in some cases human activities can be a contributing factor in causing landslides. ... They are commonly a result of building roads and structures without adequate grading of slopes, poorly planned alteration of drainage patterns, and disturbing old landslides.

When that happens, the Earth's surface is subject to natural disasters. Events such as earthquakes, volcanoes and tsunamis all result because of plate tectonics.

There are a few farming practices that contribute to soil erosion, but tilling is probably the biggest culprit. Tilling can actually reduce the levels of organic materials in the soil, and it breaks up the soil and softens its structure, which makes it more prone to erosion by water or rain.

What are some of the possible consequences (effects) of short-term natural ecological change? (Specifically large volcanic eruptions and earthquakes). ... Earthquakes can cause landslides, altering the course of rivers or flooding large areas.

In the type of mass movement called slump, a mass of rock and soil suddenly slips down a slope. Unlike a landslide, the material in a slump moves down in one large mass. It looks as if someone pulled the bottom out from under part of the slope.

Landslides come in many forms. Rock falls occur along cliffs and outcrops where blocks of rock break off and fall down the slope. Block slides and slumps occur where blocks or masses of intact soil or rock move downslope along a failure surface. ... Slumps, on the other hand, have concave failure surfaces.

C) Mudflows deposit talus slopes. D) Mudflows can move and carry very large boulders and other coarse debris.

Man-made disasters can include hazardous material spills, fires, groundwater contamination, transportation accidents, structure failures, mining accidents, explosions and acts of terrorism.

The way people use land can affect the levels of nutrients and pollution in soil. Any activity that exposes soil to wind and rain can lead to soil loss. Farming, construction and development, and mining are among the main activities that impact soil resources. ... Over time, many farming practices lead to the loss of soil.

2)soil creep is due to the gradient of the hill and the effect of gravity; soil flow is due to the freeze-thaw activity in the area whereas landslides are due natural causes(vibrations due to earthquakes or volcanic activities) in the areas of where human caused damages to the environment are already present.

Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land.

Sliding allows the materials to fall downward in an inclined plane, whereas slumping allows the materials to fall downwcard along a curved plane. Explanation: Sliding and slumping are two of the distinct mass wasting processes, where the loose and unconsolidated materials falls downward under the influence of gravity.

A. No. Like landslides, earthquakes do involve earth movement, however a separate earthquake policy is needed for quake-caused property damage as the causes of the movement are different. Landslides are caused by erosion or water accumulation that destabilizes the land, while earthquakes are caused by seismic activity.

Factors such as relief, channel slope, basin size, seasonality of rains and tectonic activities control sediment loads in rivers. Human interventions in the form of reservoirs for water storage have impounded and trapped huge sediment loads on the continental parts.

Positive Impacts • The weathering of rocks helps to form the basic component of soil. Soil is very essential for Human Activities . ... Negative Impacts • Erosion by flowing water during floods causes extensive damage to human properties and they also destroy lives. Floods can cause crops and livestock destruction.
