The surface of the Earth is broken into several large and many small tectonic plates that are less dense than the interior of the Earth. The tectonic plates move around and collide with each other, creating rifts, raising up mountains, and opening and closing oceans. New tectonic plates ...

, etc – is well understood within the context of the ~50-year-old theory of plate tectonics. This theory posits that Earth’s outer shell (Earth’s “lithosphere”) is subdivided into plates that move relative to each other, concentrating most activity along the boundaries between plates....
Inside a crowded building.Avoid rushing for the doorways, as others may do so as well. Instead, take cover away from display shelves, windows and falling objects, using something to protect your head and neck from debris. Outside.Move away from potential hazards such as utility wires,...
Divergent Plate Boundaries:Here, tectonic plates move apart, allowing mantle material to rise. This ascent reduces pressure, initiating melting, especially at mid-ocean ridges where new oceanic crust forms. Mantle Plumes (Hotspots):These are vertical columns of hot mantle rock that rise from deep ...
Our planet's outer, layer is made of tectonic plates. The Hawaiian-Emperor Seamount chain, a line of peaks on the ocean floor, was created when a tectonic plate moved over a spot where hot rock welled up from deep inside the Earth. When two tectonic plates move away from each other ...
