1b. (10 points) now let's be more realistic. what if the continental slab is 35 km thick (both still have an area of 1 km2) and the oceanic slab is still 10 km thick. which is higher and by how much? which goes deeper into the asthenosphere and by how much? 10 km 35 km

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.
