What happens when two tectonic plates move apart?
Magma seeps up through the two plates from the mantle and form volcanos.
When plates beneath the ocean move apart from one another what happens to the magma below?
Magma is extruded as lava at the mid-ocean ridges when they are pulled apart.
What do plates do at divergent plate boundaries?
At divergent plate boundaries, plates move away from each other due to the upwelling of magma from the mantle. This process creates new oceanic crust as the plates separate. As the plates move apart, they create features such as mid-ocean ridges and rift valleys.
What does magma rising between separate plates create?
When magma rises between separate plates, it can create new land masses or volcanic islands. This process is known as seafloor spreading, where the magma hardens to form new crust as the plates move apart. It can also result in volcanic activity and the formation of underwater mountain ranges.
What cause seafloor spreading?
valconoes!
How can magma cause the plates that carry the continents to move apart?
magma is very hot so as it boils it moves the plates of the earth causing the continents to slowly move apart
How plates move at divergent boundaries?
Plates are moved at a divergent boundary by the magma pushing upwards.
How plates move at a divergent boundary?
Plates are moved at a divergent boundary by the magma pushing upwards.
What is stresses in tectonic plates?
Magma moving underneath the earth causes tectonic plates to move about.
What allows the tectonic plates in the lithosphere to move?
the hot magma moves around and they move.
Why do plates move first year?
they move because its due to the magma and they move to form things etc.....
What causes the Continental and oceani plates to move?
The tectonic plates move because of the great amount of liquid rock, or magma that they 'float' on and get pushed by.
How does the earth's plates move on top of the crust?
The Earth's tectonic plates do not move on top of the crust, they are the crust. The crust is made out of plates. The plates float on top of the mantle, which is made of molten rock, called magma. The plates move because of currents in the magma.
Why does magma often form at the boundary between separating tectonic plates?
the tectonic plates move and the lava rises
What happens at spreading plate boundaries?
tectonic plates move apart allowing magma to move to the surface.
What causes plates to stop moving temporarily?
Friction causes plates to stop moving temporarily. The motion of the magma under the plates will cause the plates to move again.
What happens when two tectonic plates move apart?
Magma seeps up through the two plates from the mantle and form volcanos.
