The crust is divided into two types.
The oceanic crust is made of granite.
The is the area of the upper mantle just below the lithosphere that behaves in a plastic fashion.
It is composed of several layers not including the overlying sediment.
Oceanic crust is relatively younger than continental crust.
The crust of earth is of two distinct types.
Oceanic crust makes up just 0 01 of the mass of the earth.
Is primarily made up of basalt whereas is primarily made up of granite.
The oceanic crust is similar to the continental crust except it is.
Continental landmasses crust are formed primarily of while oceanic crust is primarily made up of.
Oceanic crust is about 6 km 4 miles thick.
By contrast the continental crust is made up of light colored granite rocks full of substances like oxygen and silicon.
30 km 20 mi to 50 km 30 mi thick and mostly composed of less dense more felsic rocks such as granite.
This is why it is referred to as sima.
Hot spots are associated with.
Oceanic crust is heavier and denser 2 9 g cubic cm than continental crust 2 7 g cubic cm.
Because both continental and oceanic crust are less dense than the mantle below both types of.
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.
Which of the following are characteristics of passive continental coasts.
The oceanic crust is made up of mafic rocks which is rich in magnesium and iron.
All of the above are correct.
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.
Oceanic crust is thin and very dense.
It has a thickness of almost 7 kilometers and it is basically made of basaltic rocks.
The floor of the oceans is made up of rocks containing mainly silica and magnesium.
Continental crust is made up of landmasses whereas oceanic crust is the floor of the oceans.
Oceanic crust is mainly basalt whereas continental crust is mainly granite.
The crust overlies the solidified and uppermost layer of the mantle.
The oceanic crust is mainly made out of dark basalt rocks that are rich in minerals and substances like silicon and magnesium.
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.
It is about 7 kilometers 4 miles.
Oceanic crust is primarily composed of mafic rocks or sima which is rich in iron and magnesium.
The crust and the solid mantle layer together constitute oceanic lithosphere.
