How is the difference in density between the oceanic crust and the continental crust important?

Answer 1

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.

Answer 2

Continental Crust is made up of Silicon and Alluminium, its Thick but Lighter than the oceanic crust. WHILE, The Oceanic Crust is composed mainly of Silicon and Magnessium, its Thin and Denser than the continental crust.

Answer 3

Oceanic crust is the part of a tectonic plate that is covered by oceans and seas and the surface of which could be as low as 11 km deep in waters, while continental crust is the part of the same tectonic plate reaching above sea level. Many tectonic plates (that are always drifting) have their borders under the oceans and seas, the biggest ones obliging the other plate to slide under, or to slide in the opposite direction or to collide (where plates are of even strength) or to move apart, causing earthquakes, tsunamis and volcanic eruptions even under the seas.

Answer 4

Continental crust underlies the continents and is mainly composed of granite rock. Average thickness is about 35 km.

Oceanic crust underlies the oceans and is mainly composed of Basalt rock. Average thickness is about 7 km.

Answer 5

The difference in density between oceanic crust (which is denser) and continental crust (which is less dense) causes oceanic crust to sink beneath continental crust at convergent plate boundaries, leading to subduction zones and the formation of mountain ranges and volcanic arcs. This density contrast also influences the topography and geology of the Earth's surface and plays a role in plate tectonics.

Answer 6

The difference in density between the oceanic and the continental crusts are that the oceanic crust is denser, so how is this important? ASAP please!
