(Earth's Changing Surface)Weathering and Erosion (CONCEPT LINKS - LITERACY AND LANGUAGE THROUGH CONTENT)

By Kate Boehm Jerome

Weathering is how rocks break down and change. Soil contains weathered rock, air, water, and humus. Soil forms in layers over many years. Most plants need soil to grow. Erosion moves weathered rocks and soil around. Wind, gravity, water, and ice are forces that can cause weathering or erosion.
