The idea that Earth's lithosphere is broken up into separate plates that float onthe mantle is the theory ofA. continental driftB. seafloorC. tectonic movement spreadingD. plate tectonics Answer: 5. The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earths structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the … See more There are two types of lithosphere: oceanic lithosphere and continental lithosphere. Oceanic lithosphere is associated with oceanic crust, and is slightly denser than … See more Plate Tectonics The most well-known feature associated with Earths lithosphere is tectonic activity. Tectonic activity describes the interaction of the huge slabs of lithosphere … See more The cool, brittle lithosphere is just one of five great spheres that shape the environment of Earth. The other spheres are the biosphere (Earths living things); the cryosphere (Earths frozen regions, including … See more Most tectonic activity takes place at the boundaries of these plates, where they may collide, tear apart, or slide against each other.

Continental crust is... WebMar 30, 2024 · The only role of density in the model is to propel the cells with speed . We can use this to estimate an equivalent elevation for the earth. The viscosity value to be used is the mantle value such as m 2 /s based on inferences from the sinking speed of subducted lithosphere (Čížková et al., 2012).
WebMay 6, 2024 · The core makes up about 31% of the Earth. Lithosphere and asthenosphere are divisions based on mechanical properties: ... The density of Earth’s surface layers is much less than the overall density of the planet, as calculated from the planet’s rotation. If the surface layers are less dense than average, then the interior must be denser ... WebThe movement and behavior of the tectonic plates are affected by the properties of the lithosphere, which are in turn influenced by the layers of the Earth's interior. For example, the thickness and composition of the lithosphere are determined by the physical properties of the mantle, such as temperature, pressure, and density.
WebApr 3, 2014 · Scientifically, the Lithosphere is the least dense because it has no pressure from other layers against it. It is the crust and the upper mantle.
