Que

Which option describes how heat and the mobement of Earth's tectonic plates contribute to the formation of an ocean basin?

Heat from the mantle conducts through tectonic plates causing them to melt to form ocean basins.

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

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

Heat from the mantle conducts through the tectonic plates causing the plates to converge and form ocean basins.

Answer 1

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

Step-by-step 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.
