Basalt is more common in oceanic crust while granite is more common in continental crust.
Is oceanic crust made of basalt or granite.
It is composed of several layers not including the overlying sediment.
The oceanic crust is mainly made out of dark basalt rocks that are rich in minerals and substances like silicon and magnesium.
Basalt which defines the size shape and arrangement of igneous mineral grains in a rock.
Basalt most most of the continental crust is made up of.
All rocks of igneous origin consist of magma or molten earth that finds its way up to.
The same mineral that solidifies slowly to form granite can also erupt to form.
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
Oceanic crust is about 6 km 4 miles thick.
It forms from lava flows which extrude onto the surface and cool.
The topmost layer about 500 metres 1 650 feet thick includes lavas made of basalt that is rock material consisting largely of plagioclase and pyroxene oceanic crust differs from continental crust in several ways.
These layers are made up of gabbros that are basically basalt mixed coarse grains of minerals.
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

These gabbros contain pockets or chambers of lava that finds its way up to the floor of the ocean.
It is thinner denser younger and of different.
The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere.
Continental landmasses crust are formed primarily of while oceanic crust is primarily made up of.
The is the area of the upper mantle just below the lithosphere that behaves in a plastic fashion.
The lower layer of oceanic crust is made up of two sub layers that cover a thickness of 4 5 kilometers.
Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate 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 continental crust is made of granite and the oceanic crust is made of basalt.
