Candy cliffs of limestone and chalk
Trips to the seaside are also a handy way of brushing up on your local geology. Hunstanton Cliffs in Norfolk have earned the nickname Candy Cliffs due to their distinctive red and white horizontal stripe, caused by contrasting layers of red limestone and chalk.
The town walls of Conwy in North Wales are the perfect place to spot a rock called rhyolite. A type of granite, it is formed from an explosive type of lava. It can be best seen in the upper sections of the eastern walls.
Permian limestone in London
Cities can also be a source of geological interest. Permian limestone is found in the north east of England and refers to the Permian period in geology, which started almost 300 million years ago and itself lasted 47 million years. It’s also a well travelled rock - Permian limestone was used to build the Houses of Parliament.
