What are 2 types of minerals found in Earth's crust?
continental oceanic
Do magnetic stripes on the ocean floor oceanic crust sink back into the mantle?
Eventually the oceanic crust, along with the magnetically aligned minerals contained within, will be subducted into the mantle.
What minerals is earths oceanic crust made up of?
Silicon (Si), Magnessium (Ma), and Iron (Fe).
What is the crustal portion of each oceanic plate is composed primarily of?
Basalt rock with a layer of sedimentary rock overlaying that, covered with water saturated sediments.
What are the main types of minerals that make up the continental and oceanic plates?
c plates- bedrock and granite o plates- bastlic
Why is the main reason that oceanic crust is heavier than continental crust?
Oceanic crust is mafic in composition and continental crust is felsic in composition. Mafic minerals generally have a higher density than felsic minerals and therefore, the oceanic crust is heavier.
What are 2 types of minerals found in Earth's crust?
continental oceanic
Where can you find minerals other than earths crust?
the oceanic plate
What are 2 metamorphic minerals formed along oceanic ridges?
Minerals are not classified as metamorphic. The mid-oceanic ridges are generally considered to be areas where new basaltic crust is formed from uprising magma. The basalt is considered an igneous rock in classification.
Do magnetic stripes on the ocean floor oceanic crust sink back into the mantle?
Eventually the oceanic crust, along with the magnetically aligned minerals contained within, will be subducted into the mantle.
What are the two minerals that form rock?
There are far more than two minerals that form rocks. You have to consider that there are about 3800 known minerals found on Earth. However, two minerals that are extremely abundant in continental and oceanic rock are feldspar and quartz.

Basalt rock with a layer of sedimentary rock overlaying that, covered with water saturated sediments.
What is the result when continental plates meet oceanic plates?
If the plates are moving toward each other, the more dense oceanic plate will subduct underneath the less dense continental plate. Mountain ranges and volcanism may result as the water saturated subducting oceanic crust creates molten rock which attempts to rise to the surface.
What are the main types of minerals that make up the continental and oceanic plates?
c plates- bedrock and granite o plates- bastlic
Why oceanic water absorb so many minerals in it?
Ocean water absorbs a lot of minerals because water is such an excellent solvent for so many substances. Combine with that, the abundance of existing dissolved materials that can form soluble salts with many existing minerals and you have an excellent environment for dissolving minerals that start out as oxides.
How does the density of oceanic crust differ from that of continental crust?
Oceanic crust is more dense than continental crust and is comprised of mainly mafic minerals (Mg, Fe), as opposed to continental crust, which is mainly felsic (Al and Si rich).
