Scientists Report a HIDDEN BASE Beneath Antarctica That Isn’t Human-Made

A sunken microcontinent nearly three times the size of Japan, formed by volcanic hotspot activity over 30 million years (1:05). Once above sea level with forests and dinosaurs 100-20 million years ago, it sank due to crustal stretching, cooling, and sediment weight, leaving only small islands visible today (5:20).

The Kerguelen hotspot acts like an underground burner where super-hot melted rock rises steadily, building volcanic rock layer by layer as the seafloor drifts over it (3:15). This process created massive volcanic structures that eventually rose above sea level.

The distinction that separates continents from ocean basins isn't whether land is above water, but the type of crust underneath (6:45). Continental crust is thicker, lighter, and older (granite-like), while oceanic crust is thinner, heavier, and younger (basalt-based).

A 34-million-year-old landscape preserved under thick ice near Aurora and Schmidt subglacial basins (10:30). The thick, slow-moving ice protected this terrain from erosion, preserving ancient river traces and valleys from before Antarctica froze.
