The specific gravity, on average, of continental crust is 2.7. For oceanic crust, it's 2.9.
crust on a pizza (thin & thick) or the earth's crust
The solid crust floats on the asthenosphere because it is less dense than the underlying semi-solid asthenosphere. This buoyancy is due to the difference in densities between the materials, with the less dense crust able to "float" on the more dense asthenosphere.
Crustal rock is normally less dense than mantle rock.
True. Continental crust is primarily composed of lighter rocks such as granite, which are less dense than the basaltic rocks found in oceanic crust. This is why continental crust is thicker and less dense than oceanic crust.
The oceanic plate is thin, dense, and makes up the ocean floor. The continental plate is less-dense, thick, and make up the continents.
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
Continental crust is thicker but less dense, and oceanic crust is thinner but more dense, making it heavier.
The continental crust is less dense and thicker than oceanic crust, allowing it to float higher on the asthenosphere. This is because the continental crust is composed of less dense rock types like granite, while the oceanic crust is made up of denser basalt. As a result, the less dense continental crust floats higher due to its lower density and greater thickness compared to oceanic crust.
less dense than the material of the Earth's mantle
The two types of lithospheric crust are continental crust, which is thicker and less dense than oceanic crust, and oceanic crust, which is thinner and more dense than continental crust.

The crust is the outermost layer of the Earth's surface. It is solid rock and can be classified into two types: continental crust, which is thicker and less dense, and oceanic crust, which is thinner and more dense.
