Which ocean basin has spread the greatest distance during the last 2 million years?

The Pacific Ocean basin has spread the greatest distance. 1. approximately 80 km 2.

.

Beside this, do ocean basins spread uniformly over the entire basin?

Based on the date from all 3 ocean basins, they so spread uniformly over the entire basin because of Paleomagnetism. Paleomagnetism is the study of changes in Earth’s magnetic field, which is shown by patterns of magnetism in rocks that formed over time. A rock’s paleomagnetism does not change.

what are the ages for the North and South Atlantic basins? The age of the North Atlantic basin (from question 2 in 7.6C) is 269.23 Ma and the age of the South Atlantic basin is 133.33 Ma.

Thereof, what is the approximate distance across the South Atlantic Ocean?

1,600 mi/2,575 km) is between SW Senegal, W Africa, and NE Brazil, E South America. The principal arms of the Atlantic Ocean are Hudson and Baffin bays, the Gulf of Mexico, and the Caribbean Sea in the west; the Baltic, North, Mediterranean, and Black seas in the east; and the Weddell Sea in the south.

How is paleomagnetism related to seafloor spreading?

Seafloor spreading carried new oceanic crust away from the mid-ocean ridge. This explanation of magnetic striping by paleomagnetism convinced scientists that new oceanic crust was being continually formed at mid-oceanic ridges. Seafloor spreading was accepted as a reality.
