How is crust different from lithosphere quizlet?
The crust is the thin, outermost layer of the Earth that is composed differently than the mantle. The lithosphere is a thick layer that contains both the crust and the upper mantle (which is rigid compared to the underlying asthenosphere).
What is the difference between the continental crust and the oceanic crust list two differences?
Continental crust is low in density whereas oceanic crust has a higher density. Continental crust is thicker, on the contrary, the oceanic crust is thinner. Continental crust floats on magma freely but oceanic crust floats on magma scarcely. Continental crust cannot recycle whereas oceanic crust can recycle it.
How do Earth’s crust and mantle differ?
This layered structure can be compared to that of a boiled egg. The crust, the outermost layer, is rigid and very thin compared with the other two. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth.
What are differences between the crust mantle and core?
The crust is a silicate solid, the mantle is a viscous molten rock, the outer core is a viscous liquid, and the inner core is a dense solid.
What are the main differences between the oceanic lithosphere and the continental lithosphere?
Oceanic lithosphere is typically about 50-100 km thick (but beneath the mid-ocean ridges is no thicker than the crust). The continental lithosphere is thicker (about 150 km). It consists of about 50 km of crust and 100 km or more of the uppermost mantle.
Does the crust rest on the lithosphere?
The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
What are the characteristics of the lithosphere?
Another distinguishing characteristic of the lithosphere is its flow properties. Under the influence of the low-intensity, long-term stresses that drive tectonic motion, the lithosphere is like a rigid shell. It changes mainly by breaking (“brittle failure”).
What is the lithosphere vs asthenosphere?
The Lithosphere is composed of the crust and upper most solid mantle. While the Asthenosphere, which lies beneath the lithosphere, is composed of the upper most weaker part of the mantle. As we move from the lithosphere to the asthenosphere the temperature increases.
What are the layers of the lithosphere?
The liquid, semi-solid, and solid land components of the lithosphere form layers that are chemically and physically different. This is why the lithosphere is further divided into sub-spheres namely the crust, the mantle, the outer core, and the inner core. The crust is made of loose soil and rocks.
What is the definition of lithosphere?
Definition of lithosphere : the solid part of a celestial body (such as the earth) specifically : the outer part of the solid earth composed of rock essentially like that exposed at the surface, consisting of the crust and outermost layer of the mantle, and usually considered to be about 60 miles (100 kilometers) in thickness
