I think it's because mantle plume is an upwelling of abnormally hot rock within the Earth's mantle.

<span>A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle. As the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.

How can you explain rock evidence of Pangea?
otez555 [7]

i. Using fossil evidences

ii. Similar rock lithologies at the edges of continent

iii. Climate clues

iv. Fitting of the continents into a puzzle

v. Sea floor spreading

Explanation:

Pangea was a super-continent on the earth which formed about 330 million years ago during the Paleozoic and began breaking up during the early Mesozoic, about 175 million years ago.

Most of the present day continents formed as a result of the separation of the Pangea in the early Mesozoic.

The first scientist to propose the existence of this super-continent was Alfred Wegener in 1912. He suggested the continental drift hypothesis to explain the separation of the land masses.

Today, the theory has been revised to the theory of plate tectonics which provides a better mechanism to understand the drifting of the continents.

Here are some of the evidences to support the existence of Pangea;

  1. Using fossil evidences: Mesosaurus, a reptile animal that lived during the Permian, was found in both South America and Southern Africa. Since this animal could not swim nor fly, only a jointed landmass could have made them present in both continents.
  2. Similar rock lithologies at the edges of continents: rock formations at the Western edge of Africa and South - Eastern part of Brazil matches with one another and have been believed to be once joined together.
  3. Climatic clues such as glacial tills that are confined to temperate and polar regions have been found in tropical regions.
  4. Wegener fitted the present day continent into a giant supercontinent and this provided a visual support for his claim.
  5. Evidences from sea floor spreading revealing magnetic reversals at divergent margins suggests the prevalence of plate tectonics i.e moving plates on earth.

This among many other evidences underscores the existence of a supercontinent called Pangea.

Bunch of points !!!!!!!!!!!!!!!!!!!!!!!

Yes they are now able to affect more cultural change. Before the women’s rights movement, women did not have much of a voice at all. Men did all the talking. Women were expected to be submissive to their husbands and be a caretaker for their husbands and children. Since the women’s rights movement, women are now able to express themselves freely. This is something they might not have gotten to do before. They are now able to choose any career they want and are encouraged to make their own choices and voice their opinions freely.
