What are the 2 types of crust and how are they different?
There are two kinds of crust: continental crust, and ocean crust. Continental crust is thicker, and predominantly felsic in composition, meaning that it contains minerals that are richer in silica. The composition is important because it makes continental crust less dense than ocean crust.
What are the type of crust give example in each type?
There are three main crust: Pâte Brisée – Pie crust. Pâte Sucrée – Sweet pie crust (shortcrust) and Pâte sablée – Rich shortcrust (sweet cookie crust or shortbread crust)
What are the 2 types of crust and which one is denser?
There are two main types of crust; continental crust and oceanic crust that differ in a number of ways. Continental crust is thicker than oceanic crust, averaging 20-70 km thick, compared to 5-10 km for oceanic crust. Continental crust is less dense than oceanic crust (2.7 g/cm3 vs. 3 g/cm3), and it is much older.
What is continental and oceanic 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 3 differences between oceanic and continental crust?
The continental crust floats much more freely on the magma. The continental crust is much thicker when compared to the oceanic crust. It has a thickness ranging from 20 mi., which is about 35 km., on the plains, to as much as 40 mi., which is about 70 km., on the highest mountains.
What are the 4 types of pie crust?
Four amazing Pie Crusts – Flaky, Brisee, Sucree, Sablee.
What is oceanic and continental 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 is a continental crust?
continental crust, the outermost layer of Earth's lithosphere that makes up the planet's continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates. The continental crust forms nearly all of Earth's land surface.
What are convergent and divergent plates?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
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 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 oceanic crust?
oceanic crust, the outermost layer of Earth's lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries. Oceanic crust is about 6 km (4 miles) thick. It is composed of several layers, not including the overlying sediment.
What is the difference between converging and diverging?
Converging tectonic plates are the one that come towards each other and form a convergent boundary while diverging tectonic plates are the one that move away from each other and form divergent boundaries.
What are the 3 main plate boundaries?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
What is the difference between 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.
What is the difference of oceanic crust and continental crust?
Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition. Like continental crust, however, oceanic crust is destroyed in subduction zones. The lavas are generally of two types: pillow lavas and sheet flows.
What is the difference of lithosphere and asthenosphere?
The lithosphere (litho:rock; sphere:layer) is the strong, upper 100 km of the Earth. The lithosphere is the tectonic plate we talk about in plate tectonics. The asthenosphere (a:without; stheno:strength) is the weak and easily deformed layer of the Earth that acts as a “lubricant” for the tectonic plates to slide over.

What is the difference between Western Ghats and Eastern Ghats?
The Western Ghats runs parallel to the western coast in a north-south direction from the Tapi River to Kanyakumari. But the Eastern Ghats runs in a north-east to a south-west direction parallel to the eastern coast from Orissa to the Nilgiri hills.
How do convex lenses differ from concave lenses *?
A convex lens or converging lens focuses the light rays to a specific point whereas a concave lens or diverging lens diverges the light rays. A lens is a transparent material (either curved or flat surface) based on the principles of refraction.
What are the 4 types of tectonic plates?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
What are the 4 types of plate margins?
There are four main types of plate boundary. These are constructive, destructive, conservative and collision margins. A constructive plate boundary occurs when two plates move away from each other.
What is the difference between convergent and divergent boundaries?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another.
