What is the percentage of continental crust on the earths surface?
Continental crust makes up about 29% of the Earth's surface. The remaining 71% is primarily covered by oceanic crust. This distribution reflects the Earth's geological processes and the differences between continental and oceanic crust in terms of composition and thickness.
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is denser than continental crust. Oceanic crust has a density of about 3 g/cm^3, while continental crust has a lower density of about 2.7 g/cm^3.
What is the average composition of the oceanic crust is thought to approximate?
granite
How oceanic crust different?
Oceanic and Contintental crust are different in composition as well as size and density Continental- granitic/50-100km thick Oceanic- basaltic/ up to 10km thick Oceanic crust is more dense making it subduct under continental crust
What is harder oceanic or continental crust?
Oceanic crust is generally denser and thinner than continental crust, which makes it harder in terms of density and composition. Oceanic crust is primarily composed of basalt, while continental crust is mainly granite, which is less dense but thicker. However, the "hardness" can also depend on specific geological contexts and factors like temperature and pressure. Overall, oceanic crust is considered harder due to its density and mineral composition.
What composition is earths crust?
oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
Would it be better to drill through the earths crust or the oceanic crust?
oceanic crust
What is the composition of earths oceans?
Many different minerals are found in oceanic crust. Feldspar, basalt, pyroxene, and other molten rock materials make up the composition of the ocean's crust.
Which portion of earths crust is more dense. oceanic or continental?
Oceanic
What is the percentage of continental crust on the earths surface?
Continental crust makes up about 29% of the Earth's surface. The remaining 71% is primarily covered by oceanic crust. This distribution reflects the Earth's geological processes and the differences between continental and oceanic crust in terms of composition and thickness.
In earths crust What type of rock is found under the oceans?
Oceanic crust, new oceanic crust is produced by seafloor spreading.
The mineral composition of the oceanic crust is similar to the composition of what rock?
The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.
What is the composition of continental crust?
The composition of the continental crust is granitic overall, high in silicon and aluminum, when compared to the oceanic crust.
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is denser than continental crust. Oceanic crust has a density of about 3 g/cm^3, while continental crust has a lower density of about 2.7 g/cm^3.
Where can you find minerals other than earths crust?
the oceanic plate
How thick is the earths oceanic crust?
one and a half miles thick
What is the average composition of the oceanic crust is thought to approximate?
granite
