What land features are formed by water erosion?
Through erosion, a river creates valleys, waterfalls, flood plains, meanders and oxbow lakes. Sediment deposited where a river flows into an ocean or lake builds up a land form called a delta.
What landforms can water create?
Rivers carry rock and soil and deposit them far away from where they were. Moving water cuts valleys into mountains. It creates canyons like the Grand Canyon. Earth’s landforms are shaped by water.
What can produce landforms through erosion?
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth’s surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.
What are three landforms created by water erosion?
The 3 landforms created by wave erosion sometimes called coastal erosion are headlands and bays, cliffs and wave cut platforms and finally caves, arches, stacks and stumps. Wave erosion is the wearing away of land and the removal of beach by wave currents.
How does wave erosion affect coastal landforms?
The process of wave erosion results in cliffs which suffer from mass wasting or land slides. Rocks are worked by the waves into sand, like a big grinder. Long shore current moves the sand from the wave action and the sand, silt and mud deposited by the inflowing rivers, along the coast to form beaches, and deltas.
How does the flow of water into the ground cause erosion?
The flow of water underground is groundwater. Groundwater is described further in the chapter Water on Earth. When water sinks into the ground, it becomes groundwater. Groundwater is a strong erosional force, as it works to dissolve away solid rock ( Figure above ).
How does rainwater move through the Earth’s crust?
Rainwater absorbs carbon dioxide (CO 2) as it falls. The CO 2 combines with water to form carbonic acid. The slightly acidic water sinks into the ground and moves through pore spaces in soil and cracks and fractures in rock. The flow of water underground is groundwater.
