Landslides can result from a variety of both natural and human causes. Factors that influence landslides include slope angle, climate, weathering, water content of the land, vegetation, geology and slope stability.Know More
Natural causes of landslides include earthquakes, volcanic eruptions, the undercutting of cliffs and banks by water erosion due to tidal waves, and the elevation of pore water pressure by prolonged rainfall and seepage. All of these natural causes are influencing factors of landslides. Together, they can create a small or large landslide that affects the geology and geography of an area.
The human causes of landslides include removal of vegetation, interference with the natural drainage of the land, leaking water or sewage pipes, overloading slopes, mining and quarrying activities, vibrations from heavy traffic, construction or mine blasting, and the excavation or displacement of rocks. Together, human and natural factors can create a landslide. Landslides can be very small and only affect the general ecology of an area, or they can be catastrophic, affecting entire communities by destroying homes and community infrastructures, impacting water and land resources, and even causing fatalities. In the United States, landslides account for approximately 15 deaths every year. Worldwide, the death toll reaches the thousands.Learn more about Earth Science
Landslides occur throughout the entire United States, but are more prevalent in certain areas of Hawaii and Alaska and in the Rocky Mountains, Appalachian Mountains and the Pacific Coastal Ranges. Landslides are most likely to happen on oversteepened slopes that fail structurally as a result of snow melting, excessive rainfall, or erosion by glaciers, ocean waves and rivers.Full Answer >
Fat fingers can result from a variety of causes. Fingers store fat just as any location on the body and may gain fat in ordinary ways. Another cause of fat fingers may be water retention, as explained by the Better Health Channel. Fluid regularly seeps into body tissues from the blood, but the lymphatic system generally removes it, placing it back in the blood stream.Full Answer >
A forest is a highly evolved, complex and constantly changing ecosystem made up of a variety of living and nonliving things, with trees making up the majority of living things. More animals live in the forest than in any other habitat on Earth. Forests contain more than 50 percent of the world's land plant and animal population.Full Answer >
Tar is a derivative of a variety of organic material, commonly consisting of small animals and plants, decomposed by high temperatures and limited exposure to oxygen. This process is referred to as destructive distillation.Full Answer >
