WebApr 8, 2024 · The continental crust is said to have been formed by re-elimination. It is a kind of accretionary process. Mostly, accretion is a process, in which small solid rock materials agglomerate to constitute large objects, such as the planets. Initially, the solid particles coming together are microscopic in nature and there is a disc of gas, as well. WebJun 20, 2024 · The formation of a continental plateau follows crustal thickening driven by plate convergence. As the continental crust thickens, it can become sufficiently hot to initiate melting (Brown, 2010; Jamieson et al., 2011; Vanderhaeghe and Teyssier, 2001). There is ample evidence for crustal melting beneath continental plateaus and orogens.

The density is how much a given volume weighs. If a block of 1m × 1m × 1m weighs 60kg, and another block the same size weighs 100kg, then the second block is more dense than the other. So if the material that makes up the continental crust is less dense, then the continental crust will be less dense.
