What drives the process of plate teconics?
Mantle convection causes the tectonic plates of the Earth to move slowly. Mantle convection is when heat moves from the mantle to the surface and causes the mantle, and the tectonic plates to move very slowly.
What happens when oceanic and continental crust meets?
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
Which force drives subduction?
An undersea mountain chain where new ocean floor is produced
Why do volcanoes occur near trenches?
Volcanoes are located often near trenches because when two tectonic plates collide at a convergent boundary, the denser plate slides under the other plate. As the denser plate bends, a deep depression known as a trench forms. At a trench, one plate moves downward into the mantle. As the plate moves farther downward into Earth's mantle, the rock is subjected to greater heat and pressure. As a result, the plate releases fluids, which causes surrounding rock to melt. This as you know is a volcano.
Does the crust of the earth move?
The crust moves like globe, for example. you know how there is rings around it? that will be the crust and the ball will be the mantle. Spin the rings, not the globe. the crust moves AROUND the mantle
Produced as a plate moves deeper into the mantle?
Trench.um no it is actually earthquakes and volcanoes... your welcome;)
Do deep focus earthquakes occur as a plate moves deeper into the mantle?
yes they do
Which theory describes the motion of earth's crust on its mantle?
plate tectonics=D
What is the force that moves a cool dense plate deep into the mantle?
ridge push
What is the definition for lithospheric plate?
The definition of Lithospheric Plate is:) Lithospheric plates are regions of Earth's crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle. Also Qwertyuiopasdfghjklzxcvbnm has nothing to do with it.
How did Africa and south America separate?
are you stupid or what !?!?!?! its so easy every continent has a plate called plate tectonics crust and mantle crust and mantle yeah yeah you know what it is plate tecttonics WELL//;.//..// It moves 2 inchs a yeah
What move through the earth's crust and mantle in a snakelike fashion?
- The Plates of the Earth (Answer)Example:Take the Pacific Plate and the North American plate. Grab them and collide themtogether, which causes earthquakes, tsunamis and other types of natural disasters. The North American Plate comes under the Pacific Plate into the deeper mantle.
What drives the process of plate teconics?
Mantle convection causes the tectonic plates of the Earth to move slowly. Mantle convection is when heat moves from the mantle to the surface and causes the mantle, and the tectonic plates to move very slowly.
What is produced when a plate moves deeper into the mantle?
As the tectonic plate gets subducted it experiences decompression melting where water is being squeezed out of the crust. At the same time the crusts is subjected to heat and pressure which causes the creation of plumes of molten rock. These plumes are now less dense and extremely hot and due to convection processes rise up. This molten rock forms a magma chamber that ultimately makes its way to the surface forming a volcano.
What happens when oceanic and oceanic crust meets?
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.

Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
What type of boundary occurs where two plates moves together causing one plate to descend into the mantle beneath the other plate?
Convergent BoundaryA destructive plate boundary with a subduction zone.
