How are continental crust and oceanic crust alike?
The oceanic crust and the continental crust are good examples of less dense layers. Both float on top of the denser mantle. Together, these layers make up the uppermost part of the earth that is collectively known as the crust.
What are the similarities and differences between oceanic crust and continental crust?
1. The oceanic crust is made up of basalt while the continental crust is made up of granite. 2. The oceanic crust is thinner while the continental crust is much thicker.
Are continental and oceanic crust have the same weight?
If you took the same volume—the same amount—of oceanic crust as continental crust then the oceanic crust would weigh about 10% more on average.
What are the two types of crust How are the two types alike How are they different?
There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt. Continental crust is less dense, thicker, and mainly composed of granite. The mantle lies below the crust and is up to 2900 km thick.
What features and characteristics are different between oceanic and continental plates?
Differences in Composition Oceanic plates are mafic in nature, composed of basalt rock and its coarse-grained equivalent, gabbro, both rich in iron, magnesium and calcium. In contrast, continental plates are felsic in nature, dominated by granitic rock with its abundant silica, aluminum, sodium and potassium.
How do continental crust and oceanic crust differ quizlet?
Continental crust is thicker than oceanic crust; continental crust is less dense than oceanic crust; the oldest continental crust is older than the oldest oceanic crust; plus the continental crust is composed of a variety of rock types, whereas oceanic crust is composed of basalt and gabbro.
What is the difference of continental and oceanic?
What is the difference between Oceanic and Continental Crust? Oceanic crust is dominated by mafic and ultramafic intrusive igneous rocks whereas continental rocks are dominated by granitic (felsic) intrusive igneous rocks.
What’s the difference between oceanic and continental crust?
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
What is the difference between oceanic plates and continental?
Continental plates have a lower density than Oceanic plates. Granite and recycled materials are much thinner than the ocean plates' thick basalt layers. Oceanic plates occupy about 71% of the Earth's surface. Continental plates make up 29% of the Earth's surface.
What is the difference between oceanic and continental crust?
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
What are the differences between oceanic and continental plates quizlet?
Oceanic plates are mainly found at destrictive plate margins because the oceanic plate subducts (goes under) the continental plate. Continental plates are where there is tectonic plate that are lighter than oceanic tectonic plate(s).
What is the difference between continental crust and oceanic crust in regards to their thicknesses and densities quizlet?
Oceanic crust is thinner and more dense. Continental crust is thicker and less dense. Difference in density is why oceanic crust subducts underneath continental crust.
What is the difference of oceanic plate and continental plate?
Continental plates have a lower density than Oceanic plates. Granite and recycled materials are much thinner than the ocean plates' thick basalt layers. Oceanic plates occupy about 71% of the Earth's surface. Continental plates make up 29% of the Earth's surface.
Which statement best describes the difference between oceanic crust and continental crust?
Which statement best describes the difference between oceanic crust and continental crust? b) Oceanic crust is thinner and denser than continental crust.
What is the difference between continental and oceanic crust quizlet?
The oceanic crust is thinner and denser, and is similar in composition to basalt (Si, O, Ca, Mg, and Fe). The continental crust is thicker and less dense, and is similar to granite in composition (Si, O, Al, K, and Na).
What is the difference between oceanic crust and continental crust quizlet?
The oceanic crust is thinner and denser, and is similar in composition to basalt (Si, O, Ca, Mg, and Fe). The continental crust is thicker and less dense, and is similar to granite in composition (Si, O, Al, K, and Na).
What is the difference between continental crust and oceanic crust in regards to their thicknesses and densities?
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
How do oceanic plates compared to continental plates quizlet?
How Are Oceanic And Continental Plates Different, And How Are They Alike? Oceanic and Continental crusts are alike because they both shift and move and grow. They differ by there rock types. Oceanic crust is made up of dense basalt while continental crust is made up of less dense granite.
What are the differences between oceanic and continental plates?
Oceanic plates are mafic in nature, composed of basalt rock and its coarse-grained equivalent, gabbro, both rich in iron, magnesium and calcium. In contrast, continental plates are felsic in nature, dominated by granitic rock with its abundant silica, aluminum, sodium and potassium.
What is difference between oceanic crust and continental crust Why do we care about what type of crust covers a tectonic plate?
It is either continental or oceanic. Continental crust is typically 30-50 km thick whilst oceanic crust is only 5-10 km thick. Oceanic crust is denser can be subducted and is constantly being destroyed and replaced at plate boundaries.
How are continental and oceanic plates different?
Continental crust is composed of granitic rocks which are made up of relatively lightweight minerals such as quartz and feldspar. By contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier.
How continental and oceanic crust differ quizlet?
The oceanic crust is thinner and denser, and is similar in composition to basalt (Si, O, Ca, Mg, and Fe). The continental crust is thicker and less dense, and is similar to granite in composition (Si, O, Al, K, and Na).
