Frequent questions
How is an arch formed in the sea?
Arches form at headlands, where rocky shores jut out into the sea. The powerful waves hit the rock from both sides of the promontory. Waves erode (wear away) the rock at sea level to form sea caves on either side. The waves end up crossing the cape, creating an arch.
What forms sea arches and sea stacks?
Lesson Summary Waves in the ocean are what we see when energy travels through water. Wave energy produces erosional formations such as cliffs, wave-cut platforms, sea arches, and sea vents. When waves reach the shore, they can form deposits such as beaches, reefs, and barrier islands. More articles
What forms when a sea arch collapses?
Another landform created by waves is called a sea arch. A sea arch forms when waves erode a layer of soft rock that is under a layer of hard rock. If a sea arch collapses, a “seastack” is created, which is a large pile of rocks in the middle of the water.
