GEOLOGY

Detailed explanation-1: -All rocks located on the floor of the Atlantic Ocean are younger than 180 million years. Atlantic Ocean crust found near the coast of Africa is older than the crust found near the mid-Atlantic ridge. When mapped, the majority of earthquakes around the world, are located at a plate boundary.

Detailed explanation-2: -The MAR separates the North American Plate from the Eurasian Plate in the North Atlantic, and the South American Plate from the African Plate in the South Atlantic. These plates are still moving apart, so the Atlantic is growing at the ridge, at a rate of about 2.5 cm per year in an east-west direction.

Detailed explanation-3: -Evidence for Tectonic Plates Earthquakes, mountain building and volcanic activity occur mostly at the boundaries of the moving plates. Only shallow earthquakes occur where plates diverge at mid-ocean ridges, whereas earthquakes extend to great depth where plates converge at subduction zones.

Detailed explanation-4: -Fossil Evidence One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined.
