What is the difference between continental lithosphere and oceanic 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.
How is continental lithosphere different from oceanic lithosphere quizlet?
How is continental lithosphere different from oceanic lithosphere? The continental lithosphere is different from the oceanic lithosphere because the continental lithosphere is mostly made of granite, is about 150km thick, and is less dense than oceanic crust.
What are the differences between continental and oceanic lithosphere How are they similar?
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.
Is continental lithosphere thicker than oceanic?
Continental lithosphere is thicker than its oceanic counterpart, and does not subduct. Its crust is also richer in radiocative elements. Moreover, heat flow beneath continents is significantly lower than under oceans (e.g., Jaupart et al., 1998), which tends to show that continents are more insulating.
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.
Why is oceanic lithosphere denser than continental lithosphere?
In the theory of tectonic plates, at a convergent boundary between a continental plate and an oceanic plate, the denser plate usually subducts underneath the less dense plate. It is well known that oceanic plates subduct under continental plates, and therefore oceanic plates are more dense than continental plates.
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 are two 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.
What’s the difference between continental and oceanic 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 continental and oceanic plates?
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 are 3 differences between oceanic and continental crust?
The difference in density has an impact on isostacy of crust floating on the semi-fluid upper mantle (asthenosphere), with continental crust (about 2.7g/cm3) rising or floating above oceanic crust (about 3.5 g/cm3). The continental crust is by far the older of the two types of crust.
What is the difference in density between oceanic and continental crust?
Continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm.
What’s the difference between oceanic and continental plates?
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.
What are the 3 differences between oceanic and continental crust?
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. 3.
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 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 the continental crust and the oceanic crust list two differences?
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.
What are the differences between continental and oceanic plates?
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.
What are the differences between continental and oceanic crust?
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 are the differences between oceanic 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 are the 3 main differences between the continental and oceanic crusts?
The oceanic crust is thinner while the continental crust is much thicker. 3. The oceanic crust is denser than the 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).
Why do continental and oceanic crust act differently?
Continents do something different from oceanic crust. If you know Earth's density, they are too buoyant to sink compared to the heavier mantle rocks underneath. This is why continental crust floats on the surface of the mantle.
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.
