The Rock Cycle: Weathering

The video explains how rocks become smooth and round through the action of waves and rubbing against each other over many years. It introduces weathering as the process that breaks down rocks and other materials on Earth's surface into smaller pieces, with agents like water, ice, and chemicals. The Grand Canyon is highlighted as an example of weathering over millions of years, with the Colorado River playing a role in erosion by carrying away weathered materials. Erosion is defined as the transportation of weathered particles from one place to another, often by water or wind.
