Trenches plate tectonics
WebFeb 28, 2024 · Under-water trenches and ridges are created by plate tectonics. The crust of the earth is covered with Oceanic and Continental plates. These plates are moving constantly but are moving very very slowly. They move because of something called convection currents. Convection currents push these plates together and apart. … Web3.9 Triple junctions. All of the plate boundaries discussed so far have involved junctions between two plates. However, there are some localities where three plates are in contact, and these are termed triple junctions.Triple junctions between three ocean ridges, such as that in the South Atlantic between the African, South American and Antarctic Plates, are …
