Lesson details
Key learning points
- Weathering is the breaking down of rocks on Earth’s surface, over time, by natural forces.
- Erosion is when land is worn away by natural forces, such as water or wind, and transported to another location.
- Weathering and erosion of rock can cause habitat loss and natural disasters.
- Different types of scientists, including geologists, work to eliminate the negative effects of weathering and erosion.
Keywords
Weathering - Weathering is a natural process that slowly breaks apart or changes rock. Heat, water, wind, living things, and other natural forces cause weathering.
Natural forces - Wind, rain, heat and cold are natural forces.
Erosion - Erosion is when bits of rock and earth are carried away from their original location, by natural forces like wind and rain.
Transportation - When objects are moved from one place to another, it is called transportation.
Geologist - A geologist is a scientist who studies what the earth is made of.
Common misconception
Children use the word weathering and erosion interchangeably to mean the same thing.
Explain the difference between these two processes, that are closely linked, through clear definitions, images and examples of where they are happening.
