What are the three differences between oceanic and continental crust?
Difference Between Oceanic and Continental Crust The oceanic crust is mainly made out of dark basalt rocks that are rich in minerals and substances like silicon and magnesium. By contrast, the continental crust is made up of light-colored granite rocks full of substances like oxygen and silicon.
What are two differences 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 oceanic and continental?
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 is the difference between oceanic 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.
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.
How are the oceanic and continental crust similar and different?
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 the two types of crust?
Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth's crust is informed by plate tectonics. “Crust” describes the outermost shell of a terrestrial planet.
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 oceanic and continental lithosphere?
Oceanic lithosphere is typically about 50-100 km thick (but beneath the mid-ocean ridges is no thicker than the crust). The continental lithosphere is thicker (about 150 km). It consists of about 50 km of crust and 100 km or more of the uppermost mantle.
What are the main differences between oceanic and continental lithosphere?
Oceanic lithosphere is typically about 50-100 km thick (but beneath the mid-ocean ridges is no thicker than the crust). The continental lithosphere is thicker (about 150 km). It consists of about 50 km of crust and 100 km or more of the uppermost mantle.
What is the difference between oceanic crust and continental crust Why do we care about what type of crust covers a tectonic plate?
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.
In what ways are the two types of crust different?
Earth's crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth's crust is informed by plate tectonics. “Crust” describes the outermost shell of a terrestrial planet.
What is the difference between continental plate and oceanic plate?
Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates.
What is the difference between continental and plate?
The main difference between plate tectonics and continental drift is that plate tectonics describes the features and movement of Earth's surface in the present and in the past whereas continental drift describes the drifting of Earth's continents on the ocean bed.
What is the difference between a continental and oceanic plate?
Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates.
What is the difference between continental crust plates and oceanic plates?
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.
