Oceanic crust is primarily made of basalt and is more dense than continental crust. It is also younger and thinner compared to continental crust.
mostly made of basalt.
Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.
Yes, basalt forms on oceanic crust through volcanic activity at mid-ocean ridges and hotspot volcanoes. It is the most common rock type on the ocean floor and is created from the solidification of molten lava.
The continental crust is made up of igneous, sedimentary, and metamorphic rocks. These rocks form the continents and the continental shelves, areas of seabed close to the shore.
