QUESTION 22.
The boundary between Indian and the Antarctic plate is marked by oceanic ridge. What type of plate boundary makes it possible?
a) Continent-Continent convergence
b) Continent-Oceanic convergence
c) Continent-Oceanic divergence
d) Oceanic-Oceanic divergence
Correct Answer:D
this could be an elementary question, but could someone explain why the answer should be D and not C instead?
since, the India-Australia plate is a continental plate and the Antarctic plate is an oceanic plate, should not the plate boundary be continent-ocean divergence instead?
Oceanic ridges are formed because of divergent boundaries. That;s why we see new rocks being formed. Thats my basis to answer. But we can also imagine as Indian plate moving North towards Eurasian plate(forming himalayas)....so moving away from any plate under it (Antarctic plate).
regarding why its D and not C...i think we shouldn't worry about if its named as a continental plate or oceanic plate. If we see the map, its "Oceanic" crust where the ridges are formed.....divergent or convergent... You can refer to a tectonic plate map in any standard atlas...its oceanic crust. Or the question framed might be wrong/ambiguous.QUESTION 22.
