The water contains sand and other materials that grind away at the rock until the cracks become a cave. Hydraulic action is what mainly does this.

Then it collapses into a stack.]]> 2018-05-03 11:59:19 UTC https://padlet.com/14jrobinson/am8071h0pyf3/wish/257602151 Stump 14jrobinson https://padlet.com/14jrobinson/am8071h0pyf3/wish/257603497 The water will still attack the stack at the base until it collapses and becomes a stump.]]> 2018-05-03 12:03:31 UTC https://padlet.com/14jrobinson/am8071h0pyf3/wish/257603497 Old Harry Rocks 14jrobinson https://padlet.com/14jrobinson/am8071h0pyf3/wish/257605482 There is a single stack of chalk standing furthest out to sea. There was once a stack known as Old Harry’s Wife, but erosion caused it to collapse into the sea, leaving just a stump.]]> 2018-05-03 12:09:11 UTC https://padlet.com/14jrobinson/am8071h0pyf3/wish/257605482 Wave Refraction 14jrobinson https://padlet.com/14jrobinson/am8071h0pyf3/wish/257610111 A wave takes the shape of a discordant coastline. When it reaches shallow water it encounters frictional drag causing the bottom of the wave to slow down and become steeper/higher. On each side of the headland, the faster parts of the wave refract in towards the headland. This concentrates more wave energy on the headland which in turn increases the rate of erosion.]]> 2018-05-03 12:22:07 UTC https://padlet.com/14jrobinson/am8071h0pyf3/wish/257610111 14jrobinson https://padlet.com/14jrobinson/am8071h0pyf3/wish/257611994 2018-05-03 12:27:03 UTC https://padlet.com/14jrobinson/am8071h0pyf3/wish/257611994
