Is basalt part of earth's crust?
Yes. Basalt occurs only in the crust; the oceanic crust is primarily basalt.Actually the mantle contains far more basalt than is in the entire crust.the oceanic crust is mostly basaltthe continental crust is mostly granite
What is the rock that makes up most of oceanic crust?
Most of the oceanic crust is made of peridotite. Some basalt and gabbro may also be found.
Would it be easier to drill through the oceanic crust or the continental crust?
Continental crust is easier. Continental crust is less dense than oceanic crust, which is made of basalt. (Basalt is very dense.)
Are basaltic igneous rocks lower in density than granitic rocks?
Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.
What is the major component of oceanic crust?
Basalt.
Does basalt form most of the earths crust?
yes
What is ocean crust?
it is basalt or oceonic crust
Do basalt and granite have an effect on the arrangement of the crust at present?
Basalt is the main rock of which the oceanic crust is composed of. Continental crust is mainly granitic.

Which type of crust is primarily made of basalt and is more dense?
Continental is made mostly of granite. Oceanic is made mostly of basalt and gabbro.
Is continental crust made mostly of basalt and is about 6 to 11 kilometers thick?
The oceanic crust is mostly basalt.

Does basalt form on the oceanic crust?
Basalt is an extrusive, volcanic rock. It commonly forms the volcanic mountains found in the Oceans - eg Hawaii is made of basalts.
What is the main type of rock in oceanic crust?
The crust is divided into two types: oceanic crust and continental crust. Oceanic crust, found under the ocean floor, is made of dense rocks such as basalt. It is about 7 kilometers (4 miles) thick. Continental crust, found under land masses, is made of less dense rocks such as granite.
