Continental crust is made up of landmasses whereas oceanic crust is the floor of the oceans.

Animated gif contiental crust gif. A volcano marks a vent where magma or molten rock reaches the Earths surface in the form of lava and associated materials. Oceanic crust is relatively younger than continental crust. However in the case of icy satellites it may be distinguished based on its phase solid crust vs.

The oceanic crust will continue to sink deeper and deeper. Because 87 Rb decays to produce 87 Sr and because there is more Rb in the crust than in the mantle the 87 Sr 86 Sr of the crust has over time changed to much higher values than the 87 Sr 86 Sr ratio in the mantle. Oceanic crust is mainly basalt whereas continental crust is mainly granite.

In geology the crust is the outermost solid shell of a rocky planet dwarf planet or natural satelliteIt is usually distinguished from the underlying mantle by its chemical makeup. Delve into the earths interior learn about its tectonic plates and their movements and discover how mountains volcanoes and earthquakes are formed. And as this continues to happen a valley or a much deeper oceanic trench develops.

Oceanic crust is about 6 km 4 miles thick. Our planet might seem fixed and rigid but a closer look reveals that it is constantly shifting under our feet. See earth crust diagram stock video clips.

The topmost layer about 500 metres 1650 feet thick includes lavas made of basalt that is rock material consisting largely of plagioclase and pyroxeneOceanic crust differs from continental crust in several ways. It is thinner denser younger and of different. Convection currents can be found in the boiling of liquid the heat of a campfire the weather and even the magma in the earth.

Continental crust is thicker 25-70 km than oceanic crust 7-10 km and is nearly 35-40km deep. The continental crust is thicker and lighter.
