Basalt.
What else can I help you with?
What is the dark colored rock that makes up the oceanic crust?
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 color and the type of rock that forms oceanic crust at mid ocean ridges?
The color of rock that forms oceanic crust at mid-ocean ridges is usually dark gray to black. The type of rock is basalt, which is rich in iron and magnesium and forms from solidified lava.
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 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 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.
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 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.
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 the dark colored rock the makes up most of the oceanic crust?
Basalt
