If you see the map of the UK
then the exposed rocks reveal a history of sedimentary stuff being laid down over hundreds of millions of years, broadly getting older the more north-west you go from Dover. So chalk, on top of limestone, on top of older stuff, etc. Devon's "Jurassic coast", for example, that would be what, 70 million years old. The Carboniferous stuff in the north west, where the coal and oil is, 300 million years old.
Okay, here's my really dumb question - these are all sedimentary rocks, so must have been laid down on top of each other, layer on layer on layer. It's 300 miles from here (Lancashire) to Dover. At some point, did Britain tip up on end to the point where 300 miles' worth of bedrock flipped up in the air? How or what caused that? And what's happened to all the more recent strata that are no longer above me, or the Peaks, or the midlands, etc?
