About What Percent Of Earth S Surface Is Ocean Floor

Using this technology 10 to 15 of the ocean floor has been mapped.

About what percent of earth s surface is ocean floor.

The ocean floor. The sediments that make up. 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 percent of the earth s surface is covered by the global ocean.

The ocean is a continuous body of salt water that covers more than 70 percent of the earth s surface. 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. A switch in technology from satellite to sonar detection is currently needed to map the ocean floor in greater detail. Ocean currents govern the world s weather and churn a kaleidoscope of life.

The total amount of solid material dissolved in water. Modern sonar detection systems can create maps of the ocean floor with resolutions of around 100 meters. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. 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.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The second largest ocean is the atlantic ocean. What is water land and clouds. Usually expressed in parts per thousand.

The percent of earth s surface covered by water. A very level area of the deep ocean floor usually lying at the foot of the continental rise. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. The boundaries between these regions have evolved over time for a variety of historical cultural geographical and scientific reasons.

Less than 3 is freshwater. Throughout history the ocean has been a vital source of sustenance transport commerce growth and inspiration. What are the three basic components of earth. It covers an estimated 20 percent of the earths surface with 106 400 000 sq km total area.
