What makes the two plate to move away from each other?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. Two plates sliding past each other forms a transform plate boundary.
What will happen when two oceanic plates move towards each other?
When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
Why do tectonics move?
Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth’s crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.
What happens when two oceanic crust collides with each other?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
What is it called when one plate moves under another?
When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.
What happens when continental plate collides with an oceanic plate?
When continental and oceanic plates collide, the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process known as “subduction.” As the oceanic plate descends, it is forced into higher temperature environments.
What happens to plate A as it collides with plate B Why?
Answer: The volcanic arc is formed to “plate A” as it collides with “plate B”. The collision of these two plates results in the oceanic current which is generated. The earthquake is produced because of the volcanic arc creation between the plate A and the plate B.
