South Atlantic Ocean Floor Diagram

During the next 30 years they continued to collaborate together.

South atlantic ocean floor diagram. While at columbia university she met bruce heezen a current geology graduate student. The north sea is a sea of the atlantic ocean located between great britain england and scotland denmark norway germany the netherlands belgium and france an epeiric or shelf sea on the european continental shelf it connects to the ocean through the english channel in the south and the norwegian sea in the north. The problem with that approach is that our oceans are vast and ships are small meaning only a tiny percentage of the ocean floor between 5 15 percent nasa estimates was mapped. South atlantic 1900 km 50 000 000 yr 3 8 cm yr the rate you calculated above for the south atlantic ocean can be used to determine the age of both the south atlantic ocean and north atlantic ocean basins.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. 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 most widely accepted limit between the south atlantic and indian oceans is a line that runs south from cape agulhas at the southern tip of africa along the 20 e meridian to antarctica.

It covers approximately 20 percent of earth s surface and about 29 percent of its water surface area. The atlantic ocean is the second largest of the world s oceans with an area of about 106 460 000 km 2 41 100 000 sq mi. There is less ambiguity about the southern boundaries of the atlantic ocean although the name southern ocean has been given to the waters surrounding antarctica.

The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american. A marine gravity map of the north atlantic ocean red dots show locations of earthquakes with magnitude 5 5 and they highlight the present day location of the seafloor spreading ridges and.

It is more than 970 kilometres 600 mi long and 580 kilometres 360. Using the distance scale shown with the ocean floor diagrams determine which ocean basin has spread the greatest distance during the last 2 million years.
