American scientists have discovered the deepest trench on the globe.

The deepest point of the Earth was discovered in East Antarctica under a glacier Denman, writes the BBC.

The depth of the depression is 3.5 kilometers below sea level. Deeper from this point is the only ocean basin.

Before this discovery the lowest point on Earth was considered to be the Dead sea, whose depth is 413 meters below sea level.

As noted, this discovery is important to explore how change in the future South pole. Scientists plan to study the highland rocks and previously unexplored mountain ranges under a glacier, which can influence the movement and melting of glaciers.
