The process is called mantle convection. This is when the heat from Earth's core causes the mantle to slowly flow, creating currents that can push and move the tectonic plates on the Earth's surface.

What pushes the tectonic plates apart?

The process that pushes tectonic plates apart is called seafloor spreading. Magma rises from the mantle through divergent boundaries, creating new oceanic crust. As the new crust forms, it pushes the existing plates away from each other, causing them to move.


The process that permits new ocean crust to form as molten rock from the mantle wells up between two oceanic plates that have moved away from each other?

This process is called seafloor spreading. It occurs at mid-ocean ridges, where two oceanic plates diverge, allowing molten rock from the mantle to rise and solidify as new crust. As the plates move apart, the newly formed crust pushes older crust away from the ridge, leading to the formation of a continuous oceanic crust.


What is the force called that pushes the magma up through the mid-ocean ridge?

The force that pushes magma up through the mid-ocean ridge is primarily due to decompression melting caused by the reduction in pressure as tectonic plates move apart. This process allows magma to rise from the mantle to the surface, leading to the formation of new oceanic crust.


How convection currents affect the plates?

Convection currents in the mantle drive plate tectonics by moving the plates above them. As the mantle heats up and rises near mid-ocean ridges, it pushes plates apart and creates new crust. As the mantle cools and sinks near subduction zones, it pulls plates downward, leading to their descent back into the mantle.


What layer of the earth are continental plates sliding on?

AnswerIt is caused by the convection currents and the heat transfer of the Earth. it is because the centre of the earth is filled with magma this creates energy and pushes the plates up, this then heats the sea and the plates float

What is the mechanism called that moves or drives the tectonic plates across the surface of the earth?

The mechanism is called plate tectonics, which is driven by the heat generated from the Earth's core and mantle. This heat causes convection currents in the mantle that move the tectonic plates above them.


Why are each of the earth's plates floating like a raft?

The Earth's plates are floating on the semi-fluid layer of the mantle, known as the asthenosphere, due to the differences in density and temperature between the plates and the underlying mantle. This movement of the plates is driven by the process of plate tectonics, where convection currents within the mantle cause the plates to move and interact with each other.


Why is the earths crust always moving?

Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.


What causes the Oceanic plates to move?

Oceanic plates move due to the process of seafloor spreading. This occurs at mid-ocean ridges where hot magma rises from the mantle, solidifies to form new crust, and pushes the existing plates apart. This movement is driven by mantle convection currents.


Describe the mechanism of plate motion?

Plate motion is primarily driven by the process of mantle convection beneath the Earth's lithosphere. Heat from the Earth's core causes material in the mantle to move in a circular pattern, exerting forces on the tectonic plates above. This causes the plates to move, resulting in processes such as subduction, seafloor spreading, and continental drift.

This process is called seafloor spreading. It occurs at mid-ocean ridges, where two oceanic plates diverge, allowing molten rock from the mantle to rise and solidify as new crust. As the plates move apart, the newly formed crust pushes older crust away from the ridge, leading to the formation of a continuous oceanic crust.


At a mid Ocean ridge how do the two tectonic plates move?

At a mid-ocean ridge, tectonic plates move apart from each other due to seafloor spreading. Magma rises up from the mantle, solidifies at the ridge, and forms new oceanic crust. This process pushes the plates away from each other, causing them to move in opposite directions.


What is the force called that pushes the magma up through the mid-ocean ridge?

The force that pushes magma up through the mid-ocean ridge is primarily due to decompression melting caused by the reduction in pressure as tectonic plates move apart. This process allows magma to rise from the mantle to the surface, leading to the formation of new oceanic crust.

Convection currents in the mantle drive plate tectonics by moving the plates above them. As the mantle heats up and rises near mid-ocean ridges, it pushes plates apart and creates new crust. As the mantle cools and sinks near subduction zones, it pulls plates downward, leading to their descent back into the mantle.


What drives the process of plate tectoincs?

The driving force behind plate tectonics is convection currents in the mantle of the Earth. Heat from the core causes material in the mantle to rise, cool near the surface, and then sink back down in a continuous cycle, which ultimately pushes and pulls the tectonic plates above them.


How do convection currents in the mantle effect lithosphere movement?

Convection currents in the mantle drive the movement of tectonic plates on the Earth's surface. As the mantle heats up and rises near mid-ocean ridges, it spreads and pushes the plates apart. When the mantle cools and sinks back down near subduction zones, it pulls the plates back together. This process of convection and plate movement is known as plate tectonics.
