Which landform is evidence of erosion by waves on rocky coasts?

Sea cliffs are evidence of erosion by waves on rocky coasts.

are sea cliffs sea arches

No, sea cliffs and sea arches are different landforms. While both are formed by erosion by waves on rocky coasts, sea cliffs are vertical or near-vertical walls of rock that rise directly from the shoreline, typically resulting from the undercutting of a rocky coastline by wave action. On the other hand, a sea arch is a natural arch or bridge formed by the erosion of sea caves. Over time, the continuous pounding of waves on the rock can erode the inside of a cave, resulting in the formation of a hole or arch through the rock.

What is the name of the landform remaining after a sea arch collapses?

The landform remaining after a sea arch collapses is called a sea stack. A sea stack is a tall, isolated pillar or column of rock that is left standing in the water after the collapse of a sea arch due to wave erosion. Sea stacks are often found along coastlines with soft or less resistant rock, where erosion is more likely to occur.

Which landform is evidence of wind erosion?

Sand dunes are a landform that is evidence of wind erosion. Sand dunes are created when windblown sand particles are deposited and shaped by the action of the wind. Wind erosion occurs as the force of the wind lifts and carries sand particles, which then collide with other surfaces or obstacles, resulting in erosion and the formation of dunes. These dunes can vary in size and shape and are typically found in desert regions or coastal areas with strong winds.
