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.

Is the thickness of Earth's crust even around the planet?
falseThe Earth's crust is quite variable in density and thickness. Some places on the ocean floors it is many miles thinner than on land.
What information from clemntine helped scientists measure the thickness of the moons?
Crust
How is the Moon's crust different on the near side from the far side?
on the near side there is less gravitational pull resulting in a thickness of 60km thick while the far side has a thickness of about 100km thick
How is earth's crust different from the moon's crust?
The Moons crust is Thicker.
What portion of each body is core for the moon?
The cumulate rocks form much of the crust. The upper part of the crust probably averages about 88% plagioclase (near the lower limit of 90% defined for anorthosite): the lower part of the crust may contain a higher percent of ferromagnesian minerals such as the pyroxenes and olivine, but even that lower part probably averages about 78% plagioclase.[8] The underlying mantle is denser and is also olivine-rich.
Which layer of the crust has an average thickness of five miles?
The oceanic crust.
What is the average thickness of the crust under the oceans?
The oceantic crust is (2-4mi)
What is the thickness of the earths crust in miles?
The average is 9 miles.The average continental crust thickness is 22 miles thick. The maximum crust thickness is 56 miles underneath the Himalayas, and is 16 miles thick at its thinnest in various places.The average oceanic crust is about 4 miles thick.For the entire Earth then, the average crust thickness is 9 miles.To scale size, the earths crust would be about the thickness of 3 ordinary sheets of paper on a basketball. The thickness of a chicken eggshell would be 16 pieces of paper on a basketball, so the earths crust is 5 times thinner than a typical egg shell. And the crust is only as thick as the egg shell at its maximum thickness underneath Nepal.Sleep tight.

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 percentage of the Earths crust is helium?
The Earth has a radius of 6,360 km. The crust varies in thickness from around 5-70 km with an average value of around 35 km. As such Earth's crust is between approximately 0.07 and 1.1 % of the total thickness of the Earth (average of 0.55 %).
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.
How does the thickness of oceanic crust compare to the thickness of continental crust?
average depth of the ocean is about 4 times greater than the average elevation of the land
Where would the thickness of the earth's crust be about 40 km?
The thickness of the Earh's crust about 40 km will be at the contenintal crust.
What layer of crust averages 25 miles in thickness?
Continental crust.
What is a typical thickness of oceanic crust?
5 km thick
What is the thickness of an earth layer?
the crust is the thickness of earths layers
