Oceanic crust is predominately made of basaltic rock with a thin layer of sedimentary rock on top. Continental crust is predominately made of granitic rock, with a thin layer of sedimentary rock covering much of the visible surface.

Which type of crust is primarily made of basalt and is more dense?

Oceanic crust is primarily made of basalt and is more dense than continental crust. It is also younger and thinner compared to continental crust.


What accounts for the difference between the oceanic crust and continental crust?

The oceanic crust is made up of basalt while continental crust is made up of mostly granite.


Where does the oceanic crust begin?

The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.


What is the difference between contiental crust and oceanic crust?

Continental crust is on top of the oceanic crust Continental crust is made of granite whereas oceanic crust is made of basalt Continental crust is partly above sea level and partly below whereas oceanic crust is always below sea level.


What are four differences between the oceanic crust and the continental crust?

1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.


Which rock makes continental and oceanic crust?

The rock that makes up both continental and oceanic crust is called basalt. Basalt is a mafic extrusive igneous rock that forms when lava cools and solidifies rapidly at the Earth's surface. It is commonly found in oceanic crust, while continental crust is made up of a variety of rocks including basalt.


Why does the oceanic sink beneath continental crust at convergent boundaries?

The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.


What are the two types of crust and which rocks make up each crust?

there are two types of crust such as the oceanic crust and the continental crust, the oceanic crust is thinner and more dense than the continental crust and is constantly being recycled via subduction upon collisions with Continental crust, and creating at mid-ocean ridges. x


Is Mount Kilimanjaro made of continental crust or oceanic crust?

Of course it's continental crust! If it were made of oceanic crust, it would be underwater or some large island starting at the bottom of the ocean floor!


What are two way the continental crust and the oceanic crust are different?

the oceanic crust is thinner, generally5-8 killometers thick, and is made of basalt, but the continental crust is an average of 30 km and is made of granite


Oceanic crust is lighter than the continental crust?

No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
