explain how a stump is made
|
-Caves happen when waves force their way into cracks in the cliff .
-The water contains sand and other materials that grind away at the rock until the cracks become a cave. -Hydraulic action is the process. If the cave is formed in a headland, it may break through to the other side forming an arch. -The arch will become bigger until it can no longer support the top of the arch. -When the arch collapses, it leaves the headland on one side and a stack on the other. -The stack will be attacked This weakens the structure and it will e collapse to form a stump. |
