Basalt !! :)
What else can I help you with?
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 are dense dark colored rocks called?
Dense dark-colored rocks are typically referred to as mafic rocks. These rocks are rich in magnesium and iron, which contribute to their darker coloration and higher density. Common examples include basalt and gabbro, both of which are formed from volcanic activity and are prevalent in 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.
What kind of rocks make up continental crust and oceanic crust?
Continental crust is mainly composed of granitic rocks such as granite and rhyolite, which are light in color and less dense. Oceanic crust is primarily composed of basaltic rocks, specifically basalt, which are dark in color and more dense than granitic rocks.
What is the dark colored rock the makes up most of the oceanic crust?
Basalt
The light colored rock that makes up most of the continental crust is what?
The light colored rock that makes up most of the continental crust is granite. It is a coarse-grained igneous rock composed mainly of quartz and feldspar minerals. Granite is less dense than the dark basaltic rock that makes up oceanic crust.
What is the dark color rock that makes up the most of the oceanic crust is?
Basalt.
What are the characteristic 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 is the rock that makes up oceanic crust?
The rock that makes up oceanic crust is primarily basalt. Basalt is a fine-grained, dark volcanic rock that forms from the cooling and solidification of molten lava at or near the Earth's surface.
What is the color and type of rock that forms oceanic crust at mid-ocean ridges?
The color of the rock that forms oceanic crust at mid-ocean ridges is dark gray to black. The rock is primarily basalt, which is a type of igneous rock formed from the solidification of molten lava.
What part of the crust is made of dark igneous basalt type rock?
Oceanic crust.
What are the characteristics of the oceanic crust?
Oceanic crust is thinner and denser than continental crust, primarily composed of basaltic rock. It is typically younger due to the process of seafloor spreading, where new crust is formed at mid-ocean ridges and pushes older crust away. Oceanic crust is also more mafic in composition compared to continental crust.
What is the main type of rock in oceanic crust?
The main type of rock in oceanic crust is basalt. Basalt is a fine-grained igneous rock formed from the rapid cooling of lava at or near the Earth's surface. It is dark in color and rich in minerals like pyroxene and plagioclase feldspar.
Why is oceanic crust darker than continental crust?
Oceanic crust is darker than continental crust because it is often composed of dense basalt, which contains minerals like pyroxene and olivine that give it a dark color. In contrast, continental crust is typically made of lighter-colored rocks, such as granite, that have different mineral compositions. The mineral content and composition of the crust can influence its overall color.
What is ocean crust made of?
The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
