Answer:
(image 1) Weathering breaks down the Earth's surface into smaller pieces. Those pieces are moved in a process called erosion, and deposited somewhere else. Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. As waves attack the shore, headlands are eroded, producing steep sea cliffs. The waves vigorously attack the portion of the cliff near sea level where joints, fissures, and softer strata are especially vulnerable. The cliffs are undermined and caves are formed. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.
