one plate, the pacific plate
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
Yes, this is true. Acutally, the tectonic plates are under all of us, even fish.
The crust is generally thicker under a mountain range compared to under the sea. This is because mountain ranges are formed by the collision of tectonic plates, which can result in the crust being pushed up and folded, leading to its thickening. In contrast, the crust under the ocean is thinner due to the process of seafloor spreading where new crust is constantly being created at mid-ocean ridges.
Tectonic plates move because they are floating on top of the liquid mantle.

Tectonic plates
An earthquake IS caused by the movement of the plates under the ocean. And there is one active site which is known as "The Ring of Fire". +++ The "Ring of Fire" is a whole set of active sites right round the Pacific Ocean, above the subductions of the sea-floor plates below the surrounding continents.
they are plates under the crust that move when are shifted
the tectonic plates shake under the earth causing earthquakes
The thickest part of tectonic plates is typically found near their centers, where the lithosphere is older and has had more time to accumulate material. This thicker part is known as the lithospheric mantle, which is located beneath the Earth's crust.
