There are three
types of erosion: wind, ice, and water. Water takes sediment downstream. It
drops off at the end making a delta. Waves erode our beaches. We can try to put a jetty in the middle of
the ocean to stop the waves but it won’t work. It only helps a little. A house
by the water can wash away because of the big waves you would not want to live
by a beach. Also there are two types of weathering: physical and chemical. Chemical weathering creates new forms of rock
into different materials. Physical weathering only the size of the rock is
changed. Weathering changes a lot of
things. A delta is formed by weathering. Water, ice, gravity, and wind is
worked by weathered rock it is called erosion. In colder parts of Earth moving
ice erodes landforms. Earth’s landforms are constantly changing.
