How much of the earth lies beneath 1000 feet of water?

Answer 1

Approximately 50% of the Earth's surface is covered by ocean, with much of that being deeper than 1,000 feet. In fact, around 60% of the ocean's volume lies below this depth, meaning a significant portion of the Earth's geology and ecosystems exists in these deep-sea environments. Thus, while less than half of the Earth's total surface area is underwater, a considerable amount of the underwater terrain is well below 1,000 feet.
