While continental crust possesses high buoyancy and low density which resists sinking, geological evidence clearly demonstrates that continental subduction does occur, making the claim that continents do not subduct incorrect.

The claim asserts that tectonic continents do not subduct due to their low density. The retrieved papers explicitly note that continental crust has high buoyancy and resistance to sinking due to low density (Papers 5, 8), which creates a barrier to subduction. However, multiple papers directly document that continental subduction does in fact occur on Earth (Papers 0, 2, 5), with large portions of continental crust descending into the mantle (Paper 5). Therefore, while the premise regarding low density and buoyancy is supported, the conclusion that continents do not subduct is contradicted by empirical evidence of continental subduction zones, resulting in a CONTESTED verdict.
