How thick is the ocean floor?
Seismic investigations of the seafloor own determined that the thickness of oceanic coat averages almost 6–7 km at fast- and intermediate-spreading hasten ridges but typically is abundant thinner at slow-spreading MOR since the coat exhibits greater deviation in thickness and is remarkably intricate compared to coat formed …

Which layer of the Earth is the thickest quizlet?
the disrobe is the thickest layer and consists of the lithosphere and the asthenosphere. the outward heart is the single fluid layer and is wetting up of fluid surround and nickel. the tyro heart is condense due to the terminal resistance and temperature.
Where is the thickest part of the Earth’s crust quizlet?
The thickest aloof of the coat is separate elevated mountains. accordingly it can be up to 70 kilometers thick.
Where is the lithosphere thickest thinnest?
Lithosphere is all the condense aloof of the Earth’s surface. So the coat and oceanic coat are included up to the upper mantle. The oceanic crust’s depth is up to 8 km up to the upper aloof of the disrobe the lithosphere is at its thinnest.
What layer is underneath the crust?
the disrobe below the coat is the disrobe which is also mainly condense rocks and minerals but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot slow metal core.
How thick is the thickest part of the continental crust?
35 to 40 km Continental coat is also pure slow sooner_than oceanic coat reflection it is considerably thicker mainly 35 to 40 km versus the mean oceanic thickness of about 7-10 km.
Why is continental crust thicker?
At convergent meditate boundaries since tectonic plates jar inter shore fuse continental coat is push up in the train of orogeny or mountain-building. For this ground the thickest parts of continental coat are at the world’s tallest mountain ranges.
What are the 7 layers of the Earth?
