About what percent of earth s surface is ocean floor.

A switch in technology from satellite to sonar detection is currently needed to map the ocean floor in greater detail. The ocean is a continuous body of salt water that covers more than 70 percent of the earth s surface. The ocean is the lifeblood of earth covering more than 70 percent of the planet s surface driving weather regulating temperature and ultimately supporting all living organisms. What is the continental shelf.

The rest is saltwater almost all of which is in the ocean the area of the world ocean is about 361 9 million square kilometers 139 7 million square miles which covers about 70 9 of earth s surface. Ocean currents govern the world s weather and churn a kaleidoscope of life. While there is only one global ocean the vast body of water that covers 71 percent of the earth is geographically divided into distinct named regions. What percent of the earth s surface is covered by the global ocean.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Average salinity is 3 5 or 35 parts 1000. The sediments that make up.

The boundaries between these regions have evolved over time for a variety of historical cultural geographical and scientific reasons. What is water land and clouds. The total amount of solid material dissolved in water. Using this technology 10 to 15 of the ocean floor has been mapped.

What are the three basic components of earth. Throughout history the ocean has been a vital source of sustenance transport commerce growth and inspiration. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Begins at the shoreline.

It covers an estimated 20 percent of the earths surface with 106 400 000 sq km total area. The ocean floor. Usually expressed in parts per thousand. Less than 3 is freshwater.

A very level area of the deep ocean floor usually lying at the foot of the continental rise.
