WebbBy 1965, investigations led to the proposal that Earth's surface was broken into seven large plates and several smaller plates. It was further suggested that Line these plates are rigid, and that their boundaries are Line 5 marked by earthquakes and Volcanic activity. In recent years, satellite pictures have documented the existence of WebbThe Indian Plate, along with modern-day Africa, Australia, Antarctica, and South America, constituted part of the supercontinent Gondwana until around 140 million years ago. As these continents drifted apart at various speeds, Gondwana disintegrated, resulting in the opening of the Indian Ocean.
