What is the dark colored rock the makes up most of the oceanic crust?
Basalt
What part of the crust is made of dark igneous basalt type rock?
Oceanic crust.
What is the innermost part of the crust?
Oceanic crust:As the name already suggests, this crust is below the oceans. There, the crust is 4-7 miles (6-11 km) thick. The rocks of the oceanic crust are very young compared with the rocks of the continental crust. The rocks of the oceanic crust are not older than 200 million years. The material of which the oceanic crust consists is for the greater part tholeiitic basalt (this is basalt without olivine). Basalt has a dark, fine and gritty volcanic structure. It is formed out of very liquid lava, which cools off quickly. The grains are so small that they are only visible under a microscope. The average density of the oceanic crust is 3g/cm³.
Why dark-colored and loose soil rich in organisms?
because organisms such as earthworms can live in a dark-colored and loose soil..
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
What is the dark colored rock the makes up most of the oceanic crust?
Basalt
What is the color and type of rock that forms oceanic crust at mid-ocean ridges?
dark colored and igneous
What is the dark color rock that makes up the most of the oceanic crust is?
Basalt.
What are the characteristics of the oceanic crust?
The rocks that makes up the oceanic crusts, are very dark, relatively thin and highly dense.

Is a rock with a fine dark texture that makes up the oceanic crust.?
Yes, the name of it is Basalt.
What part of the crust is made of dark igneous basalt type rock?
Oceanic crust.
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.
What is the oceanic crust and continental crust?
underlies the ocean floor
What is ocean crust made of?
The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
Is the continental crust a light color or dark color?
Light colored
