explain what differentiates the earth’s crust and lithosphere.

What is the relationship between crust and lithosphere?

The crust is dragged by the hot plastic fluid in the uppermost mantle, and the lithosphere is formed as only a weak interface between the lower crust and upper mantle lid above the asthenosphere in seismic earth models.

What is the difference between the lithosphere and the asthenosphere quizlet?

The lithosphere is the tectonic plate and consists of crust (continental and oceanic), Moho line, Upper Mantle Rigid. The asthenosphere is where the convection currents drive the plates apart and consist of Upper Mantle flowing.

What are 3 differences between continental crust and oceanic crust?

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.

What are two differences between oceanic crust and continental crust quizlet?

The oceanic crust is thinner and denser, and is similar in composition to basalt (Si, O, Ca, Mg, and Fe). The continental crust is thicker and less dense, and is similar to granite in composition (Si, O, Al, K, and Na).

Which statement best describes the difference between oceanic crust and continental crust?

Oceanic crust is thicker and less dense than continental crust. Oceanic crust is thinner and less dense than continental crust.

What is the relationship between the lithosphere and asthenosphere quizlet?

The relationship between the Lithosphere, Asthenosphere, and Mesosphere is the lithosphere contains the tectonic plates, the Asthenosphere the plates move on top of them, and the Mesosphere convection currents move in this layer help drive the plates in the Lithosphere.

Which region represents the asthenosphere and how does it differ from the lithosphere?

The lithosphere is rigid and is made of the crust and the upper part of the mantle. The asthenosphere is plastic and is made of the softer part of the mantle. The lithosphere is plastic and is made of continental crust. The asthenosphere is rigid and is made of oceanic crust.

What is the difference in the Moho layer and the asthenosphere?

The Mohorovicic Discontinuity is a change in composition of the rock, but it lies largely within the rigid lithosphere. The plastic asthenosphere is further down.

What is the difference between crust and core?

The crust is the outermost layer of the earth. The core is the innermost layer of the earth. Crust is about 60 km thick below high mountains and just 5-10 km below the oceans. … Core has very high temperature ranging from 4400°C to about 6000°C.

What is the difference between lithospheric plates and tectonic plates?

Tectonic plates are the different pieces of the Earth’s crust that move around as they float on top of the mantle. … Lithospheric plates are regions of Earth’s crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle.

What is the difference between plate tectonics and plate boundaries?

The difference between plate tectonics and plate boundaries is that one is a scientific theory while the other is a physical property of tectonic…

What is difference between inner core and outer core?

The inner core and the outer core are made up of similar stuff chemically (both are made mostly of iron, with a little nickel and some other chemical elements)–the difference between them is that the outer core is liquid and the inner core is solid.

What is the difference between mantle and asthenosphere?

Below the Moho, the mantle is characterized by peridotite, a rock mostly made up of the minerals olivine and pyroxene. The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth’s surface.

Are the terms lithosphere and asthenosphere equivalent respectively to crust and mantle explain?

Core, mantle, and crust are divisions based on composition. … The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow.

What is the difference between the outer core and the inner core quizlet?

What is the principal difference between the inner core and outer core? The inner core is liquid while the outer core is solid.

What are some similarities and differences between the lithosphere and the crust?

Comparison of the Lithosphere and Asthenosphere

Lithosphere	Asthenosphere
Lithosphere is composed of the crust and upper most solid mantle	Asthenosphere is composed of the upper most weaker part of the mantle
Lies beneath the atmosphere and above the asthenosphere	Lies beneath the lithosphere and above the mesosphere

How do these two crust differ?

Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor.

What is lithosphere in short answer?

Lithosphere is the solid crust or the hard top layer of the earth. It is made up of rocks and minerals. It is covered by a thin layer of soil. It is an irregular surface with various landforms such as mountains, plateaus, desert, plains, valleys, etc.

What is the relationship between the mantle and the lithosphere quizlet?

All of the crust is contained within a larger layer called the lithosphere. What is the relationship between the mantle and the lithosphere? Some of the mantle is contained within a smaller layer called the lithosphere.

What best describes the relationship between Earth’s crust and tectonic plates?

Once it reaches Earth’s surface, magma is called lava. Which of the following best describes the relationship between Earth’s crust and tectonic plates? Earth’s crust is one large tectonic plate. Earth’s crust is found between the outer core and tectonic plates.

What is the main difference between the lithosphere and the asthenosphere contrast the oceanic lithosphere and continental lithosphere?

The modern understanding of the Earth’s upper mantle is that there are two distinct components – the lithospheric part and the asthenosphere. The lithosphere, which includes the continental plates, acts as a brittle solid whereas the asthenosphere is hotter and weaker due to mantle convection.

What are two differences between the oceanic and continental crust?

1. The oceanic crust is made up of basalt while the continental crust is made up of granite. 2. The oceanic crust is thinner while the continental crust is much thicker.

How do the differences between continental and oceanic crust affect the way plates interact?

The convergent boundaries between ocean and continental plates create subduction zones. The oceanic plate is pushed under the continental plate and melted. … The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates.
