The oceanic crust and the continental crust have different densities. The density of continental crust varies but generally falls in the range of 2.6 to 2.8 g/cm³. The oceanic crust's average density is around 2.9 to 3.0 grams per cubic centimeter (g/cm³).
Oceanic crust, which is primarily composed of basaltic rocks, is denser than continental crust. This higher density is due to the basaltic composition, which is rich in iron and magnesium minerals.
The continental crust, which consists mainly of granitic rocks, has a lower average density compared to the oceanic crust. The lower density of the continental crust is primarily attributed to its granitic composition, which contains lighter minerals like quartz and feldspar.

It is also a method of promotion of their platform to the wider audience and gain political points from it. By standing firm onto their platform and managing to make it sound better than the platform of the opponents they lure the voters onto their side and increase the chances of winning the elections.
