How was India separated from Africa?

However, the southern plate carrying India underwent a radical change: About 80 million years ago, a collision with Africa cut that plate down to 3,000 kilometers — right around the time India started to speed up. The team believes the diminished plate allowed more material to escape between the two plates.

How did India split from Africa?

India was still a part of the supercontinent called Gondwana some 140 million years ago. … When this supercontinent split up, a tectonic plate composed of India and modern Madagascar started to drift away.
