What Was The Primary Force That Caused This Landslide?
Triggering events such as earthquakes heavy rain or upsetting the inclined surface through digging can help to initiate a landslide but gravity is always the primary force that enables any landslide to occur regardless of how that landslide was triggered.
What is the force that is responsible for erosion and deposition in mudslides?
Gravity can cause erosion and deposition. Gravity makes water and ice move. It also causes rock soil snow or other material to move downhill in a process called mass movement.
Which energy transformation occurs as a rock falls freely from the top of a vertical cliff?
When an object falls freely its potential energy gets converted into kinetic energy. When the object hits the ground its kinetic energy gets converted into heat energy and sound energy.
What happens to the potential and kinetic energy of a rock as it falls off a cliff?
Short answer: Explain what happens to the potential energy of a rock as it falls off the side of a cliff. The kinetic energy decreases as the potential energy increases. The kinetic energy decreases as the potential energy decreases.
What shows that a rock has kinetic energy?
example remember that rock sitting at the top of the hill? When the rock starts rolling down the hill it has kinetic energy. When the rock gets to the bottom of the hill and stops it is no longer in motion therefore it no longer has kinetic energy the energy has been converted back into potential energy.
What causes landslide?
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.
What force is mainly responsible for the erosion?
Introduction. Gravity is responsible for erosion by flowing water and glaciers. That’s because gravity pulls water and ice downhill. These are ways gravity causes erosion indirectly.
What energy change occurs when a rock falls off of a cliff?
Once the rock falls the potential energy is transformed into kinetic energy. The more potential energy the more kinetic energy. In this case the bigger the rock or the taller the cliff the more kinetic energy!
What force causes thermal energy?
Since the friction force is non-conservative the work done is not stored as potential energy. All the work done by the friction force results in a transfer of energy into thermal energy of the box-floor system.
What energy has the falling rock?
The gravitational potential energy it had from being above the ground is converted to kinetic energy as the rock falls. As kinetic energy increases the velocity of the rock will also increase.
What happened to the potential energy of the rock as it being raised by?
NO!! The rock is not moving so there is no change in its potential energy hence no kinetic energy that can be harnessed and used for electricity!
What will happen to the object’s kinetic energy KE and potential energy PE when it falls from a cliff?
As an object falls under the influence of gravity kinetic energy and potential energy are equal everywhere/at the halfway point only.
What happened to the kinetic and potential energy at the lowest point of the pendulum?
At its highest point (Point A) the pendulum is momentarily motionless. … At the lowest point (Point D) the pendulum has its greatest speed. All of the energy in the pendulum is kinetic energy and there is no gravitational potential energy. However the total energy is constant as a function of time.
What energy store is sound?
Sound is a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid. Therefore the medium acts as storage for both potential and kinetic energy.
Can energy be lost?
Does a person playing a guitar applies potential energy?
The primary source of the energy comes from your body!
You move your fingers and arm to play the guitar! … Now the strings are vibrating having kinetic energy but also having the elastic energy (or potential energy) because the strings do stretch a little bit.
What is movement landslide?
What is the primary role water plays in triggering landslides?
Water can trigger landslides and mudslides because it alters the pressure within the slope which leads to slope instability. Consequently the heavy water-laden slope materials (soil rock etc.) will succumb to the forces of gravity. Excessive water is thought to be one of the most common triggers for landslides.
What causes landslides in the Philippines?
The combination of mountainous and hilly regions that experience earthquakes as well as intense rainfall brought on by monsoons or typhoons make the terrain naturally susceptible to landslides. … As the country’s population continues to grow many are settling in landslide-prone areas.
How do animals cause erosion?
Animals cause erosion in other ways too. When too many animals live in one place they tend to eat and trample all the plants. Without the plants to protect the soil it is much more likely to be eroded by wind and water. Animals cause weathering and erosion on rocky shorelines.
What are the 4 main causes of erosion?
- Water. Water is the most common cause of soil erosion. …
- Wind. Wind can also make soil erode by displacing it. …
- Ice. We don’t get much ice here in Lawrenceville GA but for those that do the concept is the same as water. …
- Gravity. …

What landforms are created by landslides?
Landslides may create lakes when the rocky material dams a stream. If a landslide flows into a lake or bay they can trigger a tsunami. Landslides often occur on steep slopes in dry or semi-arid climates.
What kind of energy is in a battery?
chemical energy
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another through an external circuit. The flow of electrons provides an electric current that can be used to do work.Feb 25 2016
What kind of energy is in a moving skateboard *?
What form of energy is possessed by a moving object?
The energy associated with an object’s motion is called kinetic energy. A speeding bullet a walking person and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant random bouncing of atoms or molecules.
Why does friction cause heat?
How do you determine force from potential energy?
Is thermal energy a force?
Energy Transfer
But an even more useful way to think about work is as a means by which energy is transferred. … Energy is transferred from a mechanical form into thermal (through an internal non-conservative force).
Does the sun give off energy?
Every day the sun radiates (sends out) an enormous amount of energy. It radiates more energy each day than the world uses in one year. Solar energy is a renewable energy source. The sun’s energy comes from within the sun itself.
What energy is in a tree?
This stored energy is called potential energy. An object has potential energy because of its position. For example leaves on trees have potential energy because they could fall.
What type of energy is gasoline?
Why does a rock have potential energy?
The rock hanging above the ground has a form of stored energy called gravitational potential energy. This form of energy is due to the downward pull of Earth’s gravity. Gravitational potential energy depends on an object’s mass and its height above the ground.
What force is acting on a rock that is rolling down a mountain?
Because it is rolling you know that static friction acts on the rock.
When a rock is dropped from a height what happens to its gravitational potential energy?
Object Falling from Rest
As an object falls from rest its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. K.E. = J which is of course equal to its initial potential energy.
