What does the hydroplate theory describe?

The hydroplate theory provides an explanation for the separation of granitic crust due to the presence of water trapped beneath the Earth's surface. This theory suggests that water was once stored beneath the crust in vast quantities, and as tectonic processes occurred, this water exerted pressure on the crustal plates. The separation of granitic crust is attributed to this high-pressure water, which played a significant role in the structural dynamics of the Earth's lithosphere.

Proponents of the hydroplate theory argue that the sudden release of this subsurface water could lead to catastrophic geological changes, including the potential for flooding events and reformation of landmasses. This concept emphasizes the importance of water not just as a surface-level feature but as a significant factor influencing geological movements and crust formation.

In contrast, the other options mentioned do not relate directly to the core principle of hydroplate theory. The formation of minerals pertains more to geological processes involving temperature and chemical reactions rather than the influence of subsurface water. The subduction of tectonic plates involves the movement of one tectonic plate beneath another, which doesn't specifically address the water interaction proposed by the hydroplate theory. Lastly, the composition of the Earth's core deals with the materials and processes occurring deep within the Earth, separate from the
