What layer of crust averages 25 miles in thickness?
Continental crust.
Differences of the continental crust and oceanic crust?
Thickness - continental = much thickerDensity - oceanic crust is denser than continental, which is why the oceanic crust subducts under the continental at destructive plates boundaries.
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Because its less dense
What is the thickness of the earth's crust?
The Earth's oceanic crust is very thin at the mid-ocean ridges, and gradually thickens as it moves away from the ridges. The continental crust is thickest under mountain ranges. The average depth of oceanic crust is around 5 miles. The average depth of continental crust is 22 miles.
What Compare and contrast oceanic crust with continental crust both types of crust?
The surface of the earth that is found on the continents is called the continental crust, which has a thickness of around 25 to 70 km. This crust is made up of igneous, sedimentary and metamorphic rocks, and that together make up the structure of our continents. As the name implies, oceanic crust is the floor of the oceans. Obviously, this crust is thinner than the continental crust. The major type of rocks making up oceanic crust is basalt. In general, the thickness of oceanic crust is around 7 to 10 km. what they have in common is continental and oceanic crust are both destroyed in subduction zones and lie atop Earth's mantle, though they differ in thickness, density, age and chemical composition.

Continental crust.
What is the average thickness of Earth's crust?
The Earths Crust can be divided between Oceanic Crust and Continental Crust. Oceanic and Continental Crust are quiet different. The thickness of oceanic crust is between 5km and 10km. It is made of mainly basalt, grabbo and diabise. The thickness of continental crust is between 30km and 50km. It is made up of lighter rocks such as granite.

What are the differences between the continental crust and the oceanic crust?
CONTINENTAL CRUST is 35km of thickness and oceanic is 7 km. i hope that helped
40 to 70 km thick?
the thickness of continental crust
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Because its less dense
What are the three differences between oceanic and Continental crust?
CONTINENTAL CRUST is 35km of thickness and oceanic is 7 km. i hope that helped
Does seafloor displaces more of the mantle that the same thickness of the continental crust?
Yes
What is the difference between the thickness of the continetal crust and oceanic crust?
In technical terms, the oceanic crust is denser than the continental crust so when the continental crust and the oceanic crust meet the continental crust will sink under and the oceanic crust will slide over and a volcano will be formed as well as producing earthquakes in the process.
What is the thickness in miles of the earths crust?
Oceanic and continental combined is approximately 25 miles.
Why does the thickness of the Earth's crust range from 6 to 70km?
Earth's crust varies in thickness due to differences in composition and the effects of plate tectonics. Oceanic crust is thinner and more dense than continental crust, and thinnest where plates are diverging from each other. Continental crust is thickest at mountain ranges, where the crust has been thickened by plate collision or thermal uplift.
