Earth's surface is always changing through weathering, erosion, and deposition, and sometimes quickly through earthquakes and volcanoes. In this lesson you understand how water and wind break down rocks and carry them away, and how sand dunes and deltas form.
💡 Tip: Put the processes in order like a story: weathering breaks the rock apart, erosion carries the pieces away, and deposition drops them in a new place when the water or wind slows down.
Ghada explains the lesson and answers your questions about it. Log in to get started.
Weathering is breaking rocks into smaller pieces where they are, and erosion is carrying those pieces and soil from one place to another by water, wind, or ice.
Physical weathering breaks rock apart without changing what it is made of, such as water freezing in its cracks and widening them. Chemical weathering changes the rock's material itself, such as rusting of rocks that contain iron or acid rain dissolving limestone.
