The type of crust underlying the continents, including the continental shelves. The continental crust is commonly about 35 to 70 km thick. Its density is typically 2.7 g/CM3, and the velocities of primary seismic waves traveling through the crust are less than 6.2 km/sec. Contrast with oceanic crust.
The type of the Earth's crust that directly underlies the continents. It ranges in thickness from 35 km to as much as 70 km under mountain ranges. The density of the upper layer of the continental crust is about 2.7 g/cm3, and the velocity of compressional seismic waves through it are less than about 7.0 km/sec.
Solid, outer layers of the earth, including the rocks of the continents.
The part of Earth's crust that includes and underlies the continents and continental shelves. The continental crust averages about 40 km thick.
The rigid, outer layer of relatively low density rock that makes up the continents.
Crust of the Earth generally of ' granitic' composition which lies above and is carried on the oceanic crust. It forms over very long times by the accumulation of lighter ( intermediate and acid) igneous rocks formed initially above subduction zones. These are then reworked by weathering, pressure and heat into sedimentary, metamorphic and further igneous rocks. Once continental crust is formed, it cannot be subducted and therefore builds up very slowly over time to form an as yet incomplete upper layer of the crust of the Earth
crust that makes up Earth's land; made up mostly of a relatively lightweight rock called granite
part of the Earth crust extending above the Moho and mainly composed of granitic rocks and constituting continents; thickness from 20 to 60 km.
The earth's crust that includes both the continents and the continental shelves.
Granitic portion of the Earth's crust that makes up the continents. Thickness of the continental crust varies between 20 to 75 kilometers. See sial layer.
Continental crust is the part of the Earth's crust that makes up the continents; it is roughly 20 to 75 km thick. Forward Backward
The uppermost layer of the earth that forms the continents. Unlike oceanic crust, continental crust is created and destroyed very slowly, so there is some continental crust on the earth as old as 4 billion years. Continental crust ranges from 10-70 km thick and is composed primarily of granite.
The continental crust is the layer of granitic, sedimentary, and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth's mantle and thus "floats" on top of it. Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km.
