The geology of England is mainly sedimentary. The youngest rocks are in the south east around London, progressing in age in a north westerly direction.^[1] The Tees–Exe line marks the division between younger, softer and low-lying rocks in the south east and the generally older and harder rocks of the north and west which give rise to higher relief in those regions. The geology of England is recognisable in the landscape of its counties, the building materials of its towns and its regional extractive industries.
