c. 47
d. 48
ANSWER: 47
Himalayas were born 47 million years ago after India and Eurasia smashed into each other. Scientists unearthed the first oceanic microplate in the Indian Ocean and stumbled across this discovery. Currently, there are close to 7 microplanes known in the Pacific Ocean. This is the first ancient microplate to be discovered in the Indian Ocean region. Radar beams from orbiting satellite have highlighted the age of the collision and the precise date has divided scientists for over a decade. Researchers have also made the discovery that crustal stresses caused by initial collision cracked the Antarctic Plate far away form the collisional zone and broke the fragment of a size equalling Australia’s Tasmania in a remote patch of the C. India Ocean. The microplate has been named Mamerickx Microplane after Jacqueline Mammerickx, a seafloor mapping pioneer. Mammerickx Microplate rotation is revealed through rotating pattern of grooves and hills turning the ocean topography into a jagged landscape called “abyssal hills”. These hills have recorded crustal stress indicating Himalayas came into being 47 million years ago.
