What type of mass movements makes the most changes in Earth's surface?
The mass movement that makes the most changes in Earth's surface is not air, or water, but a landslide. The four mass movements are landslide, slump, creep, and mudslide.Old Answer: air, water.
What is a sudden eruption from the surface of a star?
The sudden eruption from the surface of a star is called a plasma ejection. It is also known as a coronal mass ejection. They can be very dangerous if they happen to eject toward a planet nearby.
What are the types and descriptions of mass movements?
Mass wasting is considered by geologists as the movement of dirt, rock, sediment, and landscape downhill. Landslides, slump, creep, rock falls, debris falls, rock slides, mudslides, mudflows, lahar, avalanche, and debris flows are all types of mass wasting. Also, any kind of erosion (mechanical/chemical) moving sediment downhill.
What is the moon's mass compared to the earth's mass?
1 earth mass = 81.78 moon mass (rounded)1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)The mass of the moon is only 1.2 percent of the mass of Earth.
How does earth around its axis?
The Earth is the accumulation of many pieces of material from space. each piece with its own speed, mass, and impact angle. The Earth's spin is the net accumulation of all the contributing parts. The spin of the Earth is not invariant - it alters a little, caused by the inter-action with the Moon. And major earth movements (tectonic plate shifts, earthquakes etc) will also have a small effect as they re-distribute the mass around the Earth.
What is one of the most dramatic triggers of sudden mass movements?
One of the most dramatic triggers of sudden mass movements is a seismic event, such as an earthquake or a volcanic eruption. These events can rapidly displace large amounts of rock and debris, leading to landslides, rockslides, or avalanches. The sudden release of energy can result in devastating consequences for both the environment and nearby communities.
Is creep the most destructive mass movement?
No, creep is not typically considered the most destructive mass movement. Other types of mass movements, such as landslides and rockfalls, may cause more damage due to their sudden and rapid nature. Creep is a slower process that can still cause damage over time, but it is generally less destructive than more sudden mass movements.
Three kinds of mass movements?
The three main types of mass movements are landslides (movement of rock, soil, and debris down a slope), mudflows (rapid flow of a mixture of water, rock, soil, and debris), and rockfalls (sudden collapse or falling of rocks from a steep slope). These mass movements can be triggered by factors such as heavy rainfall, earthquakes, or human activities.
What are the three types of mass movements?
The three types of mass movements are landslides, mudslides, and rockfalls. Landslides involve the downhill movement of rock and soil, mudslides are characterized by the rapid flow of mud and debris, and rockfalls involve the sudden downward movement of rocks along a slope.
One trigger of mass movement is the pores in sediments filling with what?
Water and sediment are common substances that can fill the pores in sediments and act as triggers for mass movements. When the pores become saturated with water, it can decrease the strength and stability of the sediment, leading to events like landslides or debris flows.
What triggers the development of tornatoes?
a cold air mass colliding with a hot air mass
What are examples of mass movement?
Examples of mass movements include protests, civil rights movements, labor strikes, and social justice movements. These movements involve a large number of people coming together to create change and advocate for a common cause.
What is a rock fall of slow mass movement?
A rock fall is a type of mass movement where rocks or large boulders detach and fall rapidly down a slope. On the other hand, slow mass movements refer to gradual downhill movement of soil, rocks, and debris due to factors like weathering, gravity, or water saturation. Therefore, a rock fall is characterized by its sudden and fast nature, while slow mass movements occur more slowly over time.
Why do over-steepened slopes lead to mass movements?
if the steepness of a slope exceeds the stable angle, mass movements become more likely.
A mass is tied to a string and the string is held in the hand we should move our hand but the mass should not ocillate how to do it?
Move your hand smoothly and steadily without jerking or stopping suddenly. By maintaining a constant velocity, you can prevent the mass from oscillating. Ensure there is minimal slack in the string to avoid any sudden movements that could cause the mass to swing.
What is the sudden movement of a rock masses as a result of tech tonic earthquakes?
The sudden movement in rock mass causes earthquakes. This is when the rock mass comes together and collapses.
Where are mass movements most common?
Mass movements are most common in regions with steep slopes, loose soil or rock material, heavy precipitation, and seismic activity. Areas prone to mass movements include mountainous regions, coastal cliffs, and areas with a history of landslides or rockfalls. Human activities such as deforestation and construction can also increase the risk of mass movements.
