Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.

Why is the Mariana Trench so deep?

One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.

How much of the earth is still unexplored?

Only about 5% of the world’s seafloor has been mapped in some detail. Since the ocean occupies roughly 70% of the Earth’s surface, this leaves approximately 65% of the Earth (excluding dry land) unexplored.
