Landslides

Human causd slides: Undercutting of slopes Increased water content- watering lawns, building dams Engineering important for determining places where slides may occur.

They both occur on slanted landforms, occur suddenly and unexpectedly, use gravity, are caused by large amounts of unstable mass, and are capable of massive destruction.

NO!I Cant Ans. It!

There is no exact number recorded for how many people are injured by landslides each year. However, the number reaches well into the thousands, according to the website, Disaster Center.

If you are under a landslide, it kills you. if you live near it, it might have wiped out the fields where you grow food. It might have cut off your only road to the rest of the world, if you live in the mountains. If you live on the coast and have tourists, it might have buried the best beach, thus destroying your income.

Just watch Landslide Sarah Palin. http://www.landslidesarah.com Landslide is hyperbole for winning by a large margin. Different people define "large" differently and it can mean anything from winning all the votes down to winning by a few percentage points.

Scientists usually use extensometer. But it is difficult to measure the whole landslide area.

Currently Tonga, the Philippines and Costa Rica

The conditions influencing landslides and creep include downward slope of the land and exceptional amounts of rainfall. Other conditions include the type of soil that is soaked with water and the ambient temperatures.

they all have to do with waves like seismic waves and surface wave. Also underwater earthquakes cause tsunamis and usually volcanoes produce earthquakes when they are about to erupt

Trees and plants form root systems in the soil. These roots act like nets, helping to hold the soil in place. The roots, along with shade from the trees, also keep the soil moist and healthy so that it can absorb and drain lots of water. When trees and plants get cut down, those root systems die and decompose. The soil dries out and becomes very loose. Then, when a very heavy rain falls, the soil can wash away in a mudslide. This is most likely to happen where the ground is steep, like on the side of a hill or small mountain.
On a slope, tree roots help to hold the land together and pin it to the solid ground well below the surface.

Mudslides are measured by the width of the ground that collapsed. They are also measured by the weight that fell.

Erosion and weathering typically work over long periods of time, causing change slowly. However, with global warming and loss of native plants in many areas, erosion and weathering are happening at a more rapid rate.

Yes, landslides can occur near rivers, especially in areas with steep slopes and loose soil. Factors like heavy rainfall, erosion, and human activities can all contribute to landslides near rivers. The presence of a river can also increase the likelihood of landslides due to the erosion of riverbanks and destabilization of the surrounding soil.

usually happen on landforms

Yes, just one. Stuart Diver, a 28-year-old ski instructor, lay buried under the rubble of the crushed ski lodge for three days.

it had trees and grass

Landslides are a mass of moving rocks, debris and soil. Landslides can occur in any area, although some areas are more prone to landslides (for example: California).

A landslide can occur when the force of gravity overcomes the force of friction that holds a sloped mass in place. A landslide could be triggered by the movement created by an earthquake, or simply from saturation by rainfall or other moisture sources.

in a way because landslides are when rocks or earth or debris move down a slope. a mudslide is a fast moving landslide that flows in channels
