Because Oceanic crust is more dense and the Continental Crust is mountains which are a lot taller than sea floor.
Continental crust is more buoyant than oceanic crust because it is thicker and composed mainly of less dense rocks like granite, whereas oceanic crust is thinner and denser due to its basaltic composition. This difference in density causes continental crust to float higher on the mantle, making it more buoyant.
Continental crust is less dense than oceanic crust because it is thicker and composed of lighter materials, such as granite. This lower density allows continental crust to "float" higher on the more dense mantle beneath it, creating continents.
Yes, the denser oceanic crust of the seafloor will displace more mantle material compared to the same thickness of continental crust due to its higher density. This is because the thicker, less dense continental crust floats higher on the mantle compared to the thinner, denser oceanic crust.
Continental crust is generally thicker and less dense than oceanic crust, allowing it to displace more of the mantle beneath it. The buoyancy of continental crust enables it to float higher on the mantle compared to the denser oceanic crust, which sinks deeper into the mantle. Additionally, the composition of continental crust, which includes lighter materials like granite, contributes to its ability to displace a larger volume of mantle. This difference in density and thickness results in continental crust having a greater gravitational pull on the mantle compared to oceanic crust.
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.

Continental crust is less dense and thicker than oceanic crust, causing it to float higher on the mantle. The continental crust is also compositionally different, with a greater amount of less dense materials like granite compared to the basaltic composition of oceanic crust. This difference in density and composition results in the continental crust floating higher on the mantle.

The continental crust because it is thicker than the oceanic crust
The two types of Earth's crust are continental crust and oceanic crust. Continental crust is thicker, less dense, and composed mainly of granite, while oceanic crust is thinner, denser, and made up mostly of basalt.
Continental crust is less dense than oceanic crust, so it floats higher on the mantle. This means that the same thickness of continental crust will displace less mantle compared to oceanic crust. Additionally, continental crust is composed of lighter rocks like granites, while oceanic crust is made of denser rocks like basalt.

Oceanic crust is mostly basaltic, which is denser, while continental crust is made from mostly basaltic and sedimentary rocks, which are less dense. This difference in density is why the oceanic crust sinks lower (thus the oceans) and the continental crust rides higher (thus the continents) on the mantle.
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
Oceanic crust is denser than continental crust due to its composition and age, causing it to sink lower into the mantle. The oceanic crust is also thinner and has been subjected to more intense heat and pressure, which contributes to its lower position in the mantle compared to the thicker, lighter continental crust.
