Oceanic crust is about 6 km 4 miles thick.
The oceanic crust is made of granite.
Oceanic crust is relatively younger than continental crust.
Because both continental and oceanic crust are less dense than the mantle below both types of.
It has a thickness of almost 7 kilometers and it is basically made of basaltic rocks.
Oceanic crust is mainly basalt whereas continental crust is mainly granite.
This is why it is referred to as sima.
Which of the following are characteristics of passive continental coasts.
Continental crust is made up of landmasses whereas oceanic crust is the floor of the oceans.
These rocks are also referred to as sima.
The is the area of the upper mantle just below the lithosphere that behaves in a plastic fashion.
By contrast the continental crust is made up of light colored granite rocks full of substances like oxygen and silicon.
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.
Oceanic crust is heavier and denser 2 9 g cubic cm than continental crust 2 7 g cubic cm.
Hot spots are associated with.
Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate.
Continental landmasses crust are formed primarily of while oceanic crust is primarily made up of.
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 crust and the solid mantle layer together constitute oceanic lithosphere.
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.
The oceanic crust is made up of mafic rocks which is rich in magnesium and iron.
The crust overlies the solidified and uppermost layer of the mantle.
It is composed of several layers not including the overlying sediment.
30 km 20 mi to 50 km 30 mi thick and mostly composed of less dense more felsic rocks such as granite.
The crust of earth is of two distinct types.
Oceanic crust is thin and very dense.
Oceanic crust and continental crust.
The crust is divided into two types.
The floor of the oceans is made up of rocks containing mainly silica and magnesium.
Oceanic crust is primarily composed of mafic rocks or sima which is rich in iron and magnesium.
All of the above are correct.
5 km 3 mi to 10 km 6 mi thick and composed primarily of denser more mafic rocks such as basalt diabase and gabbro.
