Due to plate tectonics still moving, it causes the Earth's oceans and continents to continue moving.
it creates waves sometomes tsunami's
There is land beneath the oceans, tectonic plate boundaries separate land masses.
The large landmasses in the Earth's oceans are the continents. There are a total of 7 continents in the world.
parts of the crust and upper mantle
Arctic
the earth can be organized into 4 oceans, 7 seas, and 7 continents

precambrian era
size of island ,continents, and body of water.
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
There is land beneath the oceans, tectonic plate boundaries separate land masses.
One third is surface and the rest is the sea.
7 continents and 5 oceans = 12
Oceans and Continents are diametrically opposite to each other
continents
Along with ocean's forming is that the land mass was all those continents were connected at one time it was Pangaea.With time the Continents continued to separate.Today we know that the Continents are still moving apart from one another. We know that they move one or 10 centimeters every year. Since it moves some ocean's get bigger, but some Oceans as the Pacific Ocean gets smaller. With that i think all the continents will continue to move apart. They think that the oceans will rise, that can cause flooding and, because of the separating of the landmass there will also be earthquakes.
