Plate tectonics theory suggests that the continent of India broke free and in its wanderings suddenly accelerated.
How does a continental plate move around? How would it suddenly accelerate?
Why did Madagascar not continue drifting with the Indian plate continent?
Or could expansion of a small planet, where the plates fit together, into a much larger planet with separated plates be an alternative answer?
More than 140 million years ago, India was part of an immense super-continent called Gondwana, which covered much of the Southern Hemisphere. Around 120 million years ago, what is now India broke off and started slowly migrating north, at about 5 centimetres per year. Then, about 80 million years ago, the continent suddenly sped up, racing north at about 15 centimetres per year, about twice as fast as the fastest modern tectonic drift.

Planet Earths continents could fit together to form a supercontinent like Pangea, or, they could alternatively fit together nearly perfectly on a smaller planet like on Mercury?
For 60 years the orthodoxy has been that these processes gradually form supercontinents, such as Gondwana or Laurasia, where a vast land mass is brought together before slowly breaking up and drifting away in pieces again. This has happened a number of times in cycles since the Earth was formed, collecting and then separating land over and over again. Now we have new information that suggests that the process is more complex than we had thought.
If planets could have or are undergoing expansion and grow larger - could they also undergo contraction, shrinking and get smaller?
Geology features on Mercury, interpreted using the solar nebular model (formation theory for how our planets formed) and geology theory, are said to show that Mercury is 'rapidly' shrinking.
But this surprise contracting is even more surprising as it is not uniform and appears to be making one side of the planet Mercury smaller.
The same data and evidence for geology and the Earths formation can also be used to back up the Expanding Earth theory. It is just how you look at it and what theory you use.
Even in 2014 plate tectonics is about to be massively modified. And plate tectonics was a relatively recent controversial change from the previous continental drift.
Below is a quote from livescience.com about Pangaea facts (not theory).
More than a century ago, the scientist Alfred Wegener proposed the notion of an ancient supercontinent, which he named Pangaea (sometimes spelled Pangea), after putting together several lines of evidence.
The first and most obvious was that the "continents fit together like a tongue and groove," something that was quite noticeable on any accurate map, Murphy said. Another telltale hint that Earth's continents were all one land mass comes from the geologic record. Coal deposits found in Pennsylvania have a similar composition to those spanning across Poland, Great Britain and Germany from the same time period. That indicates that North America and Europe must have once been a single landmass. And the orientation of magnetic minerals in geologic sediments reveals how Earth's magnetic poles migrated over geologic time, Murphy said.
Growing Earth Theory - is the earth growing or has it grown and shrunk multiple times in our past?
* The Earths Continental Crust (land) and Ocean Crust (sea floor)
are a different material and age
* The Continental rocks are much older than the newer Oceanic material
* Fresh material, which forms the Ocean Crust, is being produced at this moment by sea-floor spreading (expanding?) at the mid-ocean ridges
