All volcanoes that occur over a hotspot are not associated with plate boundaries.
|
|
|
Rocks made of basalt (charcoal colored rock), which formed at the same time, point to the same magnetic north.
|
|
|
Historical climate maps show the climates of Antarctica and Northern Africa were once the same.

None of the above

Detailed explanation-1: -Sheared-up mountain ridges and valleys form in a narrow zone where one plate slides past another at a transform plate boundary. And a mountain chain of volcanoes forms where a plate rides over a hotspot; the volcanoes get older and lower as the plate moves them away from the hotspot.
Detailed explanation-2: -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. Some life “rode” on diverging plates, became isolated, and evolved into new species.
Detailed explanation-3: -Magma generation, igneous intrusions, metamorphism, volcanic action, earthquakes, faulting, and folding are usually the result of plate tectonic activity.
