When two tectonic plates move away from each other underwater , new material rises up into Earths layer . T his process , which crea tes new ocean floor , is called seafloor sprea ding. Sometimes super-hot liquids from insid e the Earth shoot up through cracks in the oce an floor ...
Between the creation and destruction of ocean plates, sediments (沉淀物) collect on the sea floor and provide an archive of Earth’s history, the evolution of climate and life that is available nowhere else.【1】Why did the HMS Challenger make the voyage?A.To test navigation. B.To ...
Earth's own crust is split into regions called tectonic plates. They're on the move, despite outward appearances to the contrary, and their interactions have a dramatic influence on our planet. Tectonic activity at or near areas of contact between the plates is the driving force behind earthqua...

tectonic plates spreading apart, new crust being formed (ex. mid-ocean ridges, rift valleys). convergent boundaries Places where tectonic plates are coming together oceanic plates Thin plates that form the ocean floor; more dense than continental plates. continental plates plates below the continents...
The outer layer of earth, called the crust, is made up of tectonic plates. These plates usually fit together like puzzle pieces and are always shifting. The place where plates meet together and move is called a fault. The movement of the plates sometimes causes the earth to shake violently...
The Alaskan Way Viaduct is going to collapse eventually because of an earthquake. The way an earthquake occurs is because each layer( Core, Condential crust, Oceanic crust, Mantle, Athinothphre, Lithosphere, Mesosphere, Tectonic plates, Outer core, Inner core) each has different density like ...
