Question

New seafloor is constantly being created at the mid-ocean ridges, but the Earth is not getting bigger with time. Explain how this can be the case. (Hint: think about how the Earth’s crust recycles.)

Answer 1

The seabed is being created constantly because of the convection currents provided by the mantle.

Step-by-step explanation:

The bottom of the sea is being created constantly, this process is called expansion of the ocean floor and occurs due to the formation of the bottom of the ocean is related to materials coming from the mantle of the earth, which through the convection currents create a continuous movement in the bottom of the ocean , allowing its expansion.
