Answer 8

The who asteroid thing is debatable and would not be used as evidence in this sort of thing.

Newer activity is closer to the surface. In what is described, the land stuff is newer than the sea stuff.

If you get to folding land you can find exceptions to this, but until then, it is a good rule of thumb.
