Thickness of the continental crust?
40 to 70 km thick
What Ranges from 6 km to 70 km thick?
the core
How thick is eather layer?
The thickness of Earth's layers varies: the crust is between 5-70 km thick, the mantle is about 2,900 km thick, the outer core is about 2,300 km thick, and the inner core is about 1,200 km thick.
Continental crust are?
Continental crust is the thicker, less dense outer layer of Earth's lithosphere that makes up the continents. It is primarily composed of granitic rocks, such as granite and granodiorite, and is less dense than the oceanic crust, which is mainly basaltic in composition. Continental crust is relatively older than oceanic crust and can be several billion years old in some areas.
Which is larger 40 miles or 70 km?
40 miles is 64.3 kms
How thick is earths crust?
The continental crust, (where all the land is) is generally around 30 km (20 mi) to 50 km (30 mi) thick. The oceanic crust (the bottom of the sea) is roughly 5 km (3 mi) to 10 km (6 mi) thick.
How thick is the continental crust and the ocean crust?
continental: 25 to 70 km thick oceanic: 5km to 10km
How thick is the continental crust and oceanic crust?
continental: 25 to 70 km thick oceanic: 5km to 10km
How thick is the earths continental crust?
The continental crust is about 25 to 70 kilometers thick. The average is about 50 kilometers.
What is About 40 km thick on average?
The Earth's crust is about 40 km thick on average. It consists of the outermost solid shell of the Earth and is divided into tectonic plates that float on the semi-fluid asthenosphere below.
The average thickness of the crust is?
Oceanic crust is typically 6-10 km thick. Continental crust is typically 35-40 km thick, but can be a lot thicker below mountains. High mountains also have deep roots that enable them to "float" higher on the Asthenosphere. The crust there can be up to about 70 km thick or more. Note that not all crust covered by the sea is oceanic crust. Some continental shelves extend beyond the part of the continent that is above water. For example between Australia and Papua New Guinea and between Malaysia / Cambodia / Indonesia. The satellite view of Maps.google.com clearly shows how the continental shelf is extended beyond the landmass.
How thick is the Earth's lithosphere?
The lithosphere includes the Earth's crust and uppermost mantle. Oceanic lithosphere is typically about 50-100 km thick, while continental lithosphere has a range in thickness from about 40 km to perhaps 200 km.
