The continental crust is less dense and thicker than oceanic crust, which allows it to stay on top during a collision. The low density and greater thickness of continental crust help it resist subduction beneath the oceanic crust.
Oceanic crust-made up primarily of basalt-4-5 kilometers deepContinental crust-made up of granite-low density: allows it to "float" on the much higher density mantle below-20-30 miles deep
The Earth's crust is made up of low-density materials such as oxygen, silicon, and aluminum. This layer is divided into two parts: the continental crust, which is thicker and less dense than the oceanic crust.
Granitic rock forms the majority of the continental crust.
Oceanic crust is denser and thinner than continental crust, making it more likely to be subducted beneath the less dense continental crust. This process occurs because the denser oceanic crust is pulled downward into the mantle at convergent plate boundaries due to gravitational forces. The subduction of oceanic crust beneath continental crust helps to recycle Earth's materials and plays a key role in plate tectonics and the geologic cycle.

Continental crust is less dense and cooler than oceanic crust and less dense and cooler than the asthenosphere, therefore instead of subducting, it is pushed upward in a collision between continents, or floats over a subducting oceanic crust.
Oceanic crust is thin, dense and composed of mainly silicon and magnessium While the Continental crust is thicker but less dense in comparism with the oceanic crust and its composed mainly of silicon and aluminium.
Rhyolitic magma typically forms beneath continental crust due to high silica content and low temperature. The silica-rich composition leads to viscous magma, which is more common in continental settings compared to oceanic crust where magma tends to be more basaltic and less viscous.
Charcoal has a low density because it is porous and lightweight.
Granitic rock forms the majority of the continental crust.
