Answer 1

Answer:

Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.

Explanation:

Ocean basins form as a result of convection in the mantle along divergent margins.

• At a divergent margin, new crusts are being formed.
• It is said to be a constructive margin because new materials reaches through to the earth surface from there.
• The mantle convection pushes materials up  and down away from heating centers and to cold regions and back and forth.
• This leads to the creation of cells which moves the overlying plate.
• The mantle materials are then able to reach the surface to form new ocean basin.
