Kennack Sands, Cornwall (tidal range, fetch, beach angle & oceanic crust)

Kennack Sands

Thank you to Rachel and Chloe who sent this postcard from Kennack Sands in Cornwall. The beach is on the Lizard Peninsula and has a relatively large tidal range due to the shallow angle of the beach, and large waves due to the vast fetch of the Atlantic to the south west. The waves are big enough to make the area popular with surfers with wave crests of up to 4 or 5 feet high.

When you’re standing on the Lizard Peninsula, you may not realise it, but you’re actually standing on a small stretch of oceanic crust! You can learn more about coastal geography here.

Thank you again for lovely card and message.
