How did India move so fast?
In 2011, scientists believed they had identified the driving force behind India’s fast drift: a plume of magma that welled up from the Earth’s mantle. According to their hypothesis, the plume created a volcanic jet of material underneath India, which the subcontinent could effectively “surf” at high speed.
What caused India to move?
Now geologists at MIT have offered up an answer: India was pulled northward by the combination of two subduction zones — regions in the Earth’s mantle where the edge of one tectonic plate sinks under another plate. As one plate sinks, it pulls along any connected landmasses.
How did India break 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. Then, India split from Madagascar and drifted north-eastward with a velocity of about 20 cm/year.
Was India attached to Africa?

Why is India called a subcontinent?
India is a subcontinent located in South of Asian continent. It is considered a subcontinent because it covers an expansive area of land that includes the Himalayan region in the north, the Gangetic Plain as well as the plateau region in the south.
What caused the plates to break off?
Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
