What is a watery clay soil slides down a mountain?
Mudslide. Watery clay soil slides down a mountain.
What is it called when a telephone pole leans downhill?
creep. a telephone pole leans downhill.
Which type of mass movement happens very slowly?
Creep is a very slow mass movement that goes on for years or even centuries. You can’t see creep happening but leaning fences and poles and broken retaining walls show where it has taken place.
What occurs where the agents of erosion lay down sediment?
When the agents of erosion lay down sediment, deposition occurs. Deposition changes the shape of the land. Weathering, erosion, and deposition act together in a cycle that wears down and builds up Earth’s surface.
What causes mass movement quizlet?
Mass movement is the movement of earth materials called regoilth down a slope under the influence of gravity. Water and gravity cause the soil to move slowly downhill. This movement is shown on the features of the surface.
How do three processes act together to wear down and build up Earth’s surface?
Weathering, erosion, and deposition are processes that act together to wear down and build up the Earth’s surface. These processes have occurred over billions of years. Weathering is any process that breaks down rocks and creates sediments.
What are the 5 types of mass movement?
Types of mass movement
- Rockfall. Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
- Mudflow. Saturated soil (soil filled with water) flows down a slope.
- Landslide. Large blocks of rock slide downhill.
- Rotational slip. Saturated soil slumps down a curved surface.
What is flow in mass-wasting?
Mass wasting – is movement in which bed rock, rock debris, or soil moves downslope in bulk, or as a mass, because of the pull of gravity. Flow – The debris is moving downslope as a viscous fluid. A mudflow is a flowing mixture of debris and water, usually moving down a channel.
What are the 5 agents of erosion?
Find out How Water, Wind, Ice, and Waves Erode the Earth Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.
What are two agents of erosion?
Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another.
What are the 4 factors that commonly trigger mass movements?
Among the factors that commonly trigger mass movements are saturation of surface materials with water, oversteepening of slopes, removal of vegetation, and earthquakes. Geologists classify mass movements based on the kind of material that moves, how it moves, and the speed of movement.
What factor contributes to rapid mass movements the most?
Gravity: the most important factor in causing mass movements.
What is the process called when Earth’s surface is broken down into smaller pieces?
Ritseling Cave. Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
What is the difference between a mudflow and a landslide?
Landslides occur when masses of rock, earth, or debris move down a slope. 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.
What is the difference between slumping and sliding?
Sliding allows the materials to fall downward in an inclined plane, whereas slumping allows the materials to fall downwcard along a curved plane. Sliding and slumping are two of the distinct mass wasting processes, where the loose and unconsolidated materials falls downward under the influence of gravity.
What is the most dangerous type of landslide?
Volcanic landslides, also called lahars, are among the most devastating type of landslides.
What causes a debris flow?
Debris flows can be triggered in a number of ways. Typically, they result from sudden rainfall, where water begins to wash material from a slope, or when water removed material from a freshly burned stretch of land. Another major cause of debris flows is the erosion of steams and riverbanks.
What are the 4 types of mass movement?
There are four different types of mass movement:
- Rockfall. Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
- Mudflow. Saturated soil (soil filled with water) flows down a slope.
- Landslide. Large blocks of rock slide downhill.
- Rotational slip. Saturated soil slumps down a curved surface.
What are the 7 agents of weathering?
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
What is the strongest agent of erosion?
Moving water
Moving water is the strongest agent of erosion that has shaped Earth’s land surface.
