WebFeb 11, 2024 · A hotspot is a large plume of hot mantle material rising from deep within the Earth. A line of volcanoes develops as a plate moves over a hotspot, much as a line of melted wax forms as a sheet of waxed paper … WebExamples All the world’s oceans have a mid-ocean ridge beneath them. This feature usually follows the center of the ocean as basalt spreads evenly to both sides of the ridge.

WebJun 20, 2024 · The Lithosphere The crust and the rigid top part of the mantle together form what is known as the lithosphere. The lithosphere is subdivided into a number of plates. The lithosphere is made up of 7 major plates and several minor plates. These plates lie on top of the asthenosphere (the mantle’s softer and less rigid layer). WebThe higher pressure created at greater depth increases the temperature needed to melt rock. In another example, at sea level with an atmospheric pressure close to 1 bar, water boils at 100°C. But if the pressure is lowered, as shown in the video below, water boils at a much lower temperature. WebThe evidence actually says all the earth's heating from radioactive decay takes place in the mantle and crust, not the core.
