What is the composition and approximate thickness of the mantle?
Earths mantle is less dense and very hot. The mantle is 2885km thick.
If continental crust were thinner than its average thickness of 40km would it depress the mantle more or less than it does now?
If continental crust were thinner than its average thickness of 40km, it would depress the mantle less than it does now. This is because less mass in the thinner crust would exert less pressure on the mantle, resulting in less depression.
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Continental crust is less dense than oceanic crust, so it floats higher on the mantle. This means that the same thickness of continental crust will displace less mantle compared to oceanic crust. Additionally, continental crust is composed of lighter rocks like granites, while oceanic crust is made of denser rocks like basalt.
What is the relationship between mantle viscosity and the movement of tectonic plates?
The mantle viscosity, or thickness of the Earth's mantle, affects the movement of tectonic plates. A more viscous mantle slows down plate movement, while a less viscous mantle allows for faster plate movement. This relationship influences the speed and direction of tectonic plate motion.
What is the thickness of an earth layer?
The thickness of Earth's layers vary depending on the specific layer. For example, the Earth's crust can range from 5-70 km thick, the mantle is about 2,900 km thick, and the outer core is approximately 2,200 km thick. The inner core has a radius of about 1,220 km.
Thickness of lower mantle?
99,877 km
What is the average thickness of the earths upper mantle?
410km
What is the thickness of earth's mantle?
Almost 2900 km thick.
What is the thickness earth's mantle?
Almost 2900 km thick.
Is the crust larger than the mantle?
No, the crust is not larger than the mantle. The Earth's mantle is significantly thicker and makes up a larger volume of the Earth's interior compared to the crust. The crust typically ranges from about 5 to 70 kilometers in thickness, while the mantle extends to about 2,900 kilometers deep. Thus, the mantle is much larger in terms of both thickness and volume.
What is the mantles thickness in km?
The thickness of mantle is about 2,900 kilometers
If the lithosphere is 150km thick and the crust is 50 km thick how thick is the mantle?
Since the lithosphere includes both the crust and the uppermost part of the mantle, you can subtract the thickness of the crust (50 km) from the total thickness of the lithosphere (150 km) to find the thickness of the mantle. Therefore, the thickness of the mantle would be 100 km.
What is the thickness of the lower mantle?
2900 km
What is is the thickness of the upper mantle?
In oceanic areas the upper mantle is usually 5-200km thick and on continental areas it is 75-300km deep.
Why would a thickness of continental crust displace less mantle than the same thickness of oceanic crust?
Continental crust is generally thicker and less dense than oceanic crust, which is denser and thinner. When continental crust is added or displaced, it exerts less force on the underlying mantle due to its buoyancy, resulting in less mantle displacement. In contrast, the denser oceanic crust displaces more mantle when submerged or altered, leading to a greater effect on the mantle beneath it. This difference in density and buoyancy explains why the same thickness of continental crust displaces less mantle than oceanic crust.
What is the thickness of the 2 parts in the lithosphere?
both of them together is 333 kilometers. you can search the Internet for how thick the crust is and subtract that from 333 to get the thickness of the mantle part.
What is the thickness of the earths mantle?
The earths mantle is one of the four major layers, laying between the crust and the outer core. At 2885 kilometers, it is the thickest layer.
