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.

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.

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

What accounts for the difference in density between oceanic and continental crust?
The oceanic is heavier
What is the difference between a snowfield or glacier?

What is the population density of the humid continental climate?
the Continental climate population
What is the difference in density between warm and cold air?
The density between cold and warm air is, cold air is heavier than warm air.
What accounts for the difference in density between oceanic crust and contenetial crust?
Continental crust is made of granite, and forms the continents and areas of shallow seabed close to their shores. It is less dense than the material of the mantle, which consists of mafic rock. Continental crust is then less-dense than oceanic crust, which, due to sea-floor spreading, is hardened mantle/lithosphere.
What accounts for the difference in density between oceanic and continental crust?
The oceanic is heavier
What and the difference between oceanic and continental?
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.

What is the difference between the continental crust and the oceanic crusts?
Most significantly, there is a material difference in the weight and density of the two types of crust. This manifests itself when tectonic movement brings oceanic in continental plates into collision. Oceanic crust is relatively denser but typically about 100km this. Continental crust is lighter but almost twice as thick--about 200km.

What is the difference between density and relative density?
Density: the ratio mass/volume for a material, expressed in kg/m3 (SI). Relative density: the ratio between the density of a material and the density of pure water at the same temperature.

What is the difference between density and matter?
The difference is that Density is one way of measuring matter, its a math expression. While Matter is a physical substance.
