Based on the ages of the ocean floor in the Atlantic, how long ago do you think Africa and South
America split apart?

about 140 million years ago

The South Atlantic Ocean opened about 140 million years ago as Africa separated from South America. About the same time, India separated from Antarctica and Australia, forming the central Indian Ocean

Hi there! I can answer your question!

It was about 140 million years ago that the Africa and South America split apart. When the Gondwana began to split, Africa and South america also began to split with it! That is how the South Atlantic Ocean was made between Africa and South America.

                        Addition facts During the Jurassic period (180 million years ago) the western half of Gondwana was separated from the eastern half of it.The South Atlantic Ocean opened about 140 million years ago!The Africa and South America plate drifted apart, forming the Iapetus Ocean. ✅That is all! Thanks for asking this question✅

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
