Rocks and Weathering
By Oliver Smith
The rock cycle is never-ending and is constantly changing the landscape through a series of different processes. Scientists use knowledge about the formation, weathering, and erosion of rocks to study the planet's history. Students will enjoy creating visual aids to help them understand the rock cycle and types of weathering!

- BIOLOGICAL WEATHERING
- CHEMICAL WEATHERING
- TEMPERATURE CHANGES
- Biological weathering is due to animals and plants. Burrowing animals and plant roots can damage and break rocks apart.
- When rocks are weathered by chemicals it is called chemical weathering. An example of this is when acid rain reacts with limestone.
- As the temperature increases, rocks expand and then contract as the temperature falls. Over time this can cause the rock to crack and small pieces fall away.
- WIND, RAIN, WAVES
- Weathering
- FREEZE-THAW
- Wind can blow small particles which wear away the rock. Waves and rain wear the rock down over long periods of time.
- Water can get into the cracks of rocks. When the water freezes, it expands, causing the crack to get bigger. As the ice melts, the water goes deeper into the crack and can freeze again, making the crack even bigger.
