Pangaea was once a supercontinent in earth’s ancient history. Tectonic forces in earth’s mantle caused Pangaea to break apart and become the geography we see today. These forces are still at work – North America and South America are moving away from Europe and Africa a few inches a year.Click to see full answer. Keeping this in view, why did Pangea break up?Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.Beside above, how did Pangea affect life on Earth? Explanation: When there are land bridges or connections between continents, organisms tend to wander around looking for new habitats. This tends to produce fewer species. But when there is more islands or separate land masses, this tends to produce more specialized species adapted to these unique environments. Similarly one may ask, what proves that Pangea existed? Evidence of existence Additional evidence for Pangaea is found in the geology of adjacent continents, including matching geological trends between the eastern coast of South America and the western coast of Africa. The polar ice cap of the Carboniferous Period covered the southern end of Pangaea.Can Pangea happen again?But the constant movement of Earth’s tectonic plates raises a question: Will there ever be another supercontinent like Pangea? The answer is yes. Pangea wasn’t the first supercontinent to form during Earth’s 4.5-billion-year geologic history, and it won’t be the last.
