1. Explain the different landforms formed by the sea waves.
Answers
Answer:
Coastal landforms are created by waves and include stacks, stumps, caves, arches, bays, coves, beaches and cliffs. Cliffs are vertical or near-vertical walls of rock along a coast. ... Eventually, the water causes caves to form in these areas. If the water erodes all the way through, you get an arch.

What Are Coastal Landforms?
What Are Coastal Landforms?A landform is any natural feature of the Earth's surface. They include mountains, valleys, rivers, lakes and coasts; anything that isn't created or caused by man. This lesson focuses on landforms created by waves, or in other words, coastal landforms. Waves are powerful, and they can do a lot to the land that they crash into. There are many specific types of coastal landforms, including stacks, stumps, caves, arches, bays, coves, beaches and cliffs. So, let's go through them and talk about exactly how waves shape our coasts.

So, let's go through them and talk about exactly how waves shape our coasts.Types of Coastal LandformsCliffs are vertical or near-vertical walls of rock along a coast. The angles of the walls can vary, but they all transform into cliffs the same way. Cliffs start to form when waves begin crashing into the bottom of what will become the cliff. They cause erosion there and begin cutting away a hole or notch. Water takes the weathered rock away with it and deposits it elsewhere. This process is made faster by the presence of tiny bits of rock and sediment in the water itself, which are launched at the cliff. The upper part of the rock wall is also worn away from chemical processes, like acid rain, and physical processes, like water freezing in cracks, which causes them to open more. The upper rock becomes weaker and eventually collapses, forming a cliff.

The upper rock becomes weaker and eventually collapses, forming a cliff.Caves, arches, stacks and stumps are all formed as part of the same basic process. It starts with waves hitting vertical faults, or lines of weakness in rock, along the coast. The water erodes these faults, making the cracks larger and larger. Eventually, the erosion causes caves to form in these areas. If the caves are on an outcrop from the coast, the water can erode all the way through, forming an arch. The process continues until the arch becomes so small and weak that it collapses, creating a stack, or a vertical column of rock. Finally, these stacks can weather away, leaving a stump.
