What is the Average Depth of an Ocean?
Answer – The average depth of an ocean is about 3,688 meters (3.7 km / 12,100 feet).
Explanation:
Ocean depths can vary significantly from one location on Earth to another because the ocean’s bottom is not flat or uniform. The average depth value (3688 meters) was calculated by dividing the total volume of the Earth’s oceans (about 1.332 billion cubic kilometers) by the total surface area of the oceans (about 361 million square kilometers). These parameters are usually calculated by combinations of SONAR technology and satellite altimeters.
The deepest part of the world’s oceans is the Challenger Deep in the Mariana Trench. It has a depth of about 36,070 feet (10,994 meters).
