Q7. If the foams were Earth's plates, then they are oceanic crusts where one
subducts under the other Explain what happens next when there is
subduction.​

Answer:

When one oceanic plate subducts under the other, a subduction zone will form.  The oceanic plate that subducts will sink back into the mantle, forming a volcanic arc.

Explanation:

Subduction is a process that takes place when two tectonic plates collide, and one plate moves under another and is forced to sink into the mantle.

When two oceanic plates collide one oceanic plate is eventually subducted under the other. Where one plate slides under the other is referred to as the subduction zone. As the subducting plate descends into the mantle where it is being gradually heated a deep ocean trench is formed, and magma formed above the subducting plate slowly rises into the overriding crust and finally to the surface forming a volcanic arc.

When a subduction process occurs between tectonic plates, mountain formation, volcanic phenomena and deep earthquakes can occur.

This is because:

  • Subduction happens when two tectonic plates collide with each other.
  • This usually occurs between a continental plate and an oceanic plate.
  • The oceanic plate is heavier than the continental plate and the impact makes this plate "dip" below the continental plate.
  • This movement pushes the continental plate causing it to move upwards and pushes the surface of the earth, which will create a deformation in the shape of a parabola, forming a mountain.
  • The oceanic plate, in turn, will come into contact with the earth's mantle and form a volcanic arc, responsible for the volcanism.

Based on this, we can see how the movements of the tectonic plates influence the surface of the earth.
