Question

If there is constantly new sea seafloor being created along mid ocean ridges, how come the planet is not increasing in size?

Answer 1

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
