Yes. All of Earth's crust, both on land and on the seafloor, is composed of tectonic plates.
yes oil is available under the sea , theres lots of plates of oil under the sea bed
It is when the plates of the earth move under the sea
yes
Sea Weed is under the sea but I'm not sure what else
Land plates are called continental plates. Sea plates are called oceanic plates.
because of the tectonic plates under the sea were drifting actively
under water volcanoes move the oceanic plates and spread them
It creates a mid ocean ridge, the two plates pulling apart is called a divergent boundary.
An earthquake under the sea very close to Japan. Earthquakes are caused by the readjustment of the techtonic plates, and this is because the tectonic plates were converging into each other and since continental plates are more dense than oceanic plates the oceanic plates subducted into the mantle causing an earthquake under the sea. The waves slowly rolled across the ocean causing the waves to get larger as they were moving away from the focus point.
an earthquake's epicentre is under the plates and if the epicentre is near or under water, the vibrations will disturb the water and make waves or even tsunamis.
An earthquake forms by two plates colliding in any sea nearest to the country. Earthquakes form anywhere, where there is a big sea/ocean.
volcanoes can form from plates constantly moving and shifting. They can also form from convection currents from under the sea!
