When new oceanic lithosphere is generated at an oceanic ridge, what happens to the plate it's attached to?

Take a guess im getting rid of my account might as well do it in style a fishing boat, with a ladder in it, is leaning against a wall at the harbor. there are 5 oars and 2 fishing nets in the trawler. the distance between two consecutive steps on the ladder is 1 meter. if waves lashing against the wall rise a half meter in every half hour, how long will it take before 6 steps of the ladder are under the waves?

Explain: plate tectonics and people.

In a scientific experiment, a is any factor that can be changed or be changed
