Answer:
So, as per Pratt isostasy hypothesis, each slabs will sink at the same rate at the bottom but the continental slab will remain high however the oceanic slab will stay less by 10 km
Explanation:
According to the pratt hypothesis suggests., the lighter the block, the higher it stands, We also understand that in the given situation, the oceanic slab has a high density while the continental slab has a low-density relative to the oceanic slab.
So, as per Pratt isostasy hypothesis, each slabs will sink at the same rate at the bottom but the continental slab will remain high however the oceanic slab will stay less.
