The earth's crust is in motion
WebThe Earth's crust is like the skin of the apple, very thin in comparison to the other three layers. There are two types of crust: continental crust (beneath arth’s land surface) and oceanic crust (beneath the ocean floor). The continental crust is lighter (similar to granite) and the oceanic crust is denser (more like basalt). 4. WebThe plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the …

WebComposition of the Crust. Earth’s crust is largely made up of oceanic basalt and continental granite. These are both igneous rock, the term used for any rock that has cooled from a molten state. All volcanically produced rock is igneous ( Figure 8.6 ). Figure 8.6 Formation of Igneous Rock as Liquid Lava Cools and Freezes.

WebCore, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal. The core makes up about 31% of the Earth.
WebDaniel Nelson. Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global-scale flow of magma.
