What are the three forces that cause plate motion?

Convection occurs in the mantle underneath Earth’s tectonic plates. Three forces act on the plates to make them move: basal drag from convection currents, ridge push at mid-ocean ridges, and slab pull from subducting plates. Convection currents in the mantle produce a force that causes motion called basal drag.

What are three ways forces of plate motion can act?

There are three major ways that plates interact along boundaries: (1) They can move away from each other (diverge), (2) they can move toward each other (converge), or (3) they can move past each other, parallel to the boundary (transform).

What are the forces that cause plate movement?

The effect of the forces that cause the plate movement are Thermal convection, Ridge push, and Slab pull

• This further results in the rest of the plate being drawn downwards as well.
• Therefore, heat from the core of the earth and the gravitational pull is fundamental to the process of plate movements.

What are the three types of plate motion?

Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.

What are the 3 different possible causes of plate movement How do they differ from each other?

What are the 3 different possible causes of plate movement How do they differ from each other? The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.

How do driving forces and resisting forces affect plate movement?

After subducted, cool, dense lithosphere sinks into the mantle under its own weight. This helps to pull the rest of the plate down with it. resisting forces The main effect of the underlying mantle is to produce a shearing or frictional force resisting the motion of lithospheric plates.

What are the driving forces?

The impetus, power, or energy behind something in motion, as in He was clearly the driving force in the new administration. This term transfers the force that sets in motion an engine or vehicle to other enterprises.

What are the driving forces the resisting forces?

Resisting forces: The resisting forces are due to: 1) the strength of the slope materials; 2) strength added by roots; and 3) buttressing of the lower part of the slope by materials that have to be pushed or rotated out of the way before the upper part of the slope can move.

What are the types of resisting forces?

We will consider three different models of resistive forces, appropriate for different situations: friction, viscosity, and drag. Friction — When two solid objects slide over each other, each exerts a force on the other that is parallel to the interacting surfaces and in a direction to reduce the relative sliding.

What is the resisting force of plate movement?

Between two off-set spreading centres, the plates move past one another forming transform faults. Since the direction of movement is opposite, drage forces are establishd between these sections of the plate. This drag force resists plate movement away from the spreading centre.

How does gravity cause plates to move?

When the mantle pushes the edges of a tectonic plate higher, gravity can pull downward on it, causing the plate to move.

What is ridge push force?

Ridge push (also known as gravitational sliding) or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges.

How does convection cause the motion of plates that drives plate tectonics quizlet?

Part of the mantle consists of the molten material that circulates in convection currents beneath the earths crust. This process drives plate tectonics. the transfer of thermal energy (heat) from the core by the circulation or movement of Mantle material. Believed to be the driving force of plate tectonics.

How does convection cause plate movement?

convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.

How does convection cause the motion of plates that drives plate tectonics?

Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.

How do convection occur?

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.

What are three types of convection?

Types of Convection

• Natural convection.
• Forced convection.

What are 4 examples of convection?

Everyday Examples of Convection

radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.

Can conduction occur in liquids?

Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart. The rate of energy transfer by conduction is higher when there is a large temperature difference between the substances that are in contact.

Does gas happen in conduction?

Yes, conduction also takes place in liquids and gases. Every matter is made up of molecules. Heat conduction occurs in liquids and gases due to collision and diffusion of molecules during their random motion. With increase in temperature this movement of molecules increases.

How do the 3 major processes of heat transfer affect the temperature?

The temperature of the Earth is maintained by the three major processes of heat which are conduction, convection and radiation. Conduction can easily be described as the transfer of heat energy from one substance to another or within the same object. It is through conduction that the ground heats the air.

Is a fire radiation?

The thermal radiation from the fire spreads out in all directions and is able to reach you. This thermal radiation is mostly in the form of infrared waves and visible light. In contrast, the campfire heat transferred via convection shoots straight up into the sky and never reaches you (i.e. hot air billows upwards).

Is boiling water radiation?

Is boiling water a conduction convection or radiation? Boiling water is both conduction and convection. Heat from the heat source is transferred to the water from the bottom of the container through condcution and heat within the water is transferred through convection.

Is melting of ice convection?

Yes, the melting of ice is an ideal example of convection. Ice melts since heat moves to the ice from the air.
