definitions - Landslidesreport a problem A landslide, also known as a landslip, is a geological phenomenon that includes a wide range of ground movements. Rockfalls, deep failure of slopes and shallow debris flows were common.Landslides can occur in offshore, coastal and onshore environments.Although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope stability.hallow landslides can often happen in areas that have slopes with high permeable soils on top of low permeable bottom soils. The low permeable, bottom soils trap the water in the shallower, high permeable soils creating high water pressure in the top soils.

Scientists on the side of the Earth opposite the epicenter of an earthquake detect mainly what?? If I understand your question correctly you want to know what siesmologists detect on the opposite side of earth during an earthquake. First off one needs to understand that there are three kinds of shockwaves a quake releases S-waves(Secondary) and P-waves(Primary) and surface waves. S-waves travel about 2mp/s.-waves travel about 4mp/s. The speed of the surface waves is dependent on the size of the quake. But it is only the P-Waves that are able to pass through liquid. Like the core that is liquid that is how scientist were able to tell that the core of the earth was a molten ball of liquid magma.

- Landforms are formed by movements of the earth, such as earthquakes, weathering, erosions and deposits. Many landforms are created by more than one of these processes. These are called polygenetic...

Landslide A landslide or landslip are a natural disaster, something which is unfortunately unavoidable. Landslides can vary in size but usually they always involve a large ground movement. This can be things such as debris and rock failing.his means that with a large or even a small change, can cause a landslide. However, there are many things that contribute to a landslides including; 1  Erosion – if this occurs, even just slightly, can make some of the slope to fall in to oceans or rivers.

- Water is the main force that causes the deposition of sediments thereby causing landforms. Rivers and streams easily move sediment. As the rivers and streams slow, the once suspended sediments fall to the bed and begin to pile up over time.

Landslides A landslide is the movement of rock, debris or earth down a slope. They result from the failure of the materials which make up the hill slope and are driven by the force of gravity.

landslide A landslide is a large amount of earth, rock, and other material that moves down a steep slope. Landslides happen when a layer of earth or rocks separates from the layer below it. The force of gravity pulls the loose layer downward.

Landslide HazardsâAn Awareness Guide In many cases, heavy rains set off landslides. However, in many cases landslides may also occur in unpredictable was, such as the timing of a rockfall after a spring thaw. Sometime deep-seated slumps or mudflows will not move until days or weeks have passed after a storm.

definitions - Landslidesreport a problem Landslides occur when the slope changes from a stable to an unstable condition. 1  A change in the stability of a slope can be caused by a number of factors, acting together or alone. Natural causes of landslides include: 2  groundwater (pore water) pressure acting to destabilize the slope.

What landslides and debris flows are Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels. What causes landslides and debris flows. Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. Mudslides usually start on steep slopes and can be activated by natural disasters. Areas where wildfires or human modification of the land have destroyed vegetation on slopes are particularly vulnerable to landslides during and after heavy rains.

- Flow. This is the most destructive and turbulent form of landslide. Flows have a high water content which causes the slope material to lose cohesion, turning it into a slurry. They are channelled by the landscape and move rapidly.

- What are landslides and what causes them? The term landslide is a catch-all phrase that describes any geological process resulting in a downward movement from a slope of rock, soil, artificial fill, or a combination of the three under the influence of gravity.

- Three distinct physical events occur during a landslide: the initial slope failure, the subsequent transport, and the final deposition of the slide materials. Landslides can be triggered by gradual processes such as weathering, or by external mechanisms including:

- Landslides are typically associated with periods of heavy rainfall or rapid snow melt and tend to worsen the effects of flooding that often accompanies these events. In areas burned by forest and brush fires, a lower threshold of precipitation may initiate landslides.

- Scientists say that because carbon dioxide is a greenhouse gas, it is this increase that has caused average global temperatures to rise. So the question is whether this increase in atmospheric carbon dioxide and the resultant temperature rise are caused by human activities, and are therefore anthropogenic.

Changing Earth's Surface Changing Earth's Surface Video Changing Earth's Surface Weathering, erosion, and deposition act together in a cycle that wears down and builds up Earth's surface. Gravity, running water, glaciers, waves, and wind are all causes of erosion. The material moved by erosion is sediment. Weathering and erosion produce sediment. Mass movements change Earth's surface.

LESSON 4: WORLD LANDFORM PATTERNS How Volcanos are Formed. Volcanos are well-known landforms, thanks to their fiery eruptions of molten rock and lava. Volcanos are formed when molten magma from the mantle layer of the earth breaks through a crack in the crust.he Rocky Mountains are great examples of Fold Mountains. They were formed millions of years ago (which is young for a mountain!) when the Pacific plate collided with the North American plate.

A Definition A translational landslide is characterized by a planar surface of rupture, and frequently by little deformation of slide material. Physical relationships prevalent in this type of slide are the presence of relatively competent materials above and beneath a planar zone of weakness along which sliding occurs.

How Landslides Work The sediment a landslide deposits is known as its talus. The five agents of erosion are wind, water, glaciers, waves and gravity. As you learned earlier, gravity is the underlying agent of all types of mass movement. Without the force of gravity to pull sediment down an incline, a landslide would not occur.

- Earthquakes: Seismic activities have always been a main cause of landslides throughout the world. Any time plate tectonics move the soil that covers them moves with it. When earthquakes occur on areas with steep slopes, many times the soil slips causing landslides. Furthermore, ashen debris flows caused by earthquakes can also trigger mass movement of soil.

How Landslides Work Landslides occur when gravity overcomes the force of friction. Several common causes of landslides are: 1  Water: Perhaps the most common trigger of a landslide, water reduces the friction between the bedrock and the overlying sediment, and gravity sends the debris sliding downhill. 2  In sand and clay soils, a small amount of water may increase stability.

Mass wasting Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a mass, largely under the force of gravity, but frequently affected by water and water content as in submarine environments and mudflows.[1] Types of mass wasting include creep, slides, flows, ...
