|
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.
|
|
|
All volcanoes that occur over a hotspot are not associated with plate boundaries.

Detailed explanation-1: -Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.
Detailed explanation-2: -Magma generation, igneous intrusions, metamorphism, volcanic action, earthquakes, faulting, and folding are usually the result of plate tectonic activity.
Detailed explanation-3: -Which evidence best supports the claim that plate tectonics cause earthquakes? The distribution of rocks is determined by the history of plate motions.
Detailed explanation-4: -Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
