How hotspots are formed
WebThe composition of the ocean island basalts at hotspots provides a window into the composition of mantle domains in the plume conduit that melted to yield the basalts, thus providing clues as to how and when different reservoirs in the mantle formed. WebHotspots Reference Lists Plate tectonics is a scientific theory that explains the movements and behaviors of the Earth’s lithosphere, which is composed of the crust and uppermost mantle. The theory proposes that the Earth’s lithosphere is broken into a series of plates that are in constant motion, driven by the heat generated from the Earth’s core.
