Oceanic crust is relatively younger than continental crust.

The oceanic crust is made of granite.

Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate. Oceanic crust found under the ocean floor is made of dense rocks such as basalt. The is the area of the upper mantle just below the lithosphere that behaves in a plastic fashion. The topmost layer about 500 metres 1 650 feet thick includes lavas made of basalt that is rock material consisting largely of plagioclase feldspar and pyroxene.

These rocks are also referred to as sima. Continental crust is made up of landmasses whereas oceanic crust is the floor of the oceans. It has a thickness of almost 7 kilometers and it is basically made of basaltic rocks. Because both continental and oceanic crust are less dense than the mantle below both types of.

The floor of the oceans is made up of rocks containing mainly silica and magnesium. Oceanic crust makes up just 0 01 of the mass of the earth. By contrast the continental crust is made up of light colored granite rocks full of substances like oxygen and silicon. Continental landmasses crust are formed primarily of while oceanic crust is primarily made up of.

Oceanic crust is about 6 km 4 miles thick. Oceanic crust is primarily composed of mafic rocks or sima which is rich in iron and magnesium. 30 km 20 mi to 50 km 30 mi thick and mostly composed of less dense more felsic rocks such as granite. All of the above are correct.

It is about 7 kilometers 4 miles. Oceanic crust is heavier and denser 2 9 g cubic cm than continental crust 2 7 g cubic cm. Is primarily made up of basalt whereas is primarily made up of granite. The crust and the solid mantle layer together constitute oceanic lithosphere.

The crust of earth is of two distinct types. 5 km 3 mi to 10 km 6 mi thick and composed primarily of denser more mafic rocks such as basalt diabase and gabbro. It is composed of several layers not including the overlying sediment. Which of the following are characteristics of passive continental coasts.

Oceanic crust is mainly basalt whereas continental crust is mainly granite. Hot spots are associated with. It is composed of the upper oceanic crust with pillow lavas and a dike complex and the lower oceanic crust composed of troctolite gabbro and ultramafic cumulates. The oceanic crust is made up of mafic rocks which is rich in magnesium and iron.

Oceanic crust is thin and very dense. The oceanic crust is similar to the continental crust except it is. Oceanic crust and continental crust. This is why it is referred to as sima.
