The oceanic crust is made out of basalts - (lava-hardened Iron/Magnesium Silicate mixtures which solidified rapidly).
Crust under the oceans is called oceanic crust.
Approximately 60% of the ocean floor is made up of oceanic crust. Oceanic crust is typically thinner and denser than continental crust, and it forms at mid-ocean ridges through volcanic activity.
The ocean floor is mainly composed of basaltic crust known as oceanic crust. This crust is thinner and denser than continental crust and is formed through volcanic activity at mid-ocean ridges.
The crust beneath the ocean is called oceanic crust. It is thinner and younger than continental crust, primarily composed of basaltic rock formed at mid-ocean ridges through volcanic activity.
The layer of the Earth that is primarily made of rocks and soil is called the crust. The Earth's crust is the outermost layer of the planet and is divided into two types: continental crust (underlying land masses) and oceanic crust (underlying ocean basins).
Crust under the oceans is called oceanic crust.
Approximately 60% of the ocean floor is made up of oceanic crust. Oceanic crust is typically thinner and denser than continental crust, and it forms at mid-ocean ridges through volcanic activity.
Crust is made up of mainly granite, a felsic rock wit a lower density than basalt, what makes up the ocean's crust, thus why the continental crust rises up compared to ocean 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!
Ocean crust is denser
yes, it is made up of basalt, if that was your question.... ;)
The oceanic crust is made up of mafic rocks which is rich in magnesium and iron. These rocks are also referred to as sima. The oceanic crust is similar to the continental crust, except it is thinner yet denser.
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
Continental shelf.
Continental shelf.
it is basalt or oceonic crust
