Objectives:
I can explain how the process of weathering and erosion change and move materials that become soil.
I can observe the basic components of soil and relate it to plant growth.

Key points to remember:
- Small pieces of rock are called sediment.
- The breaking down of rocks is called weathering.
- Weathering can happen with water, wind, ice, and plants.
- The movement of sediments from one place to another is called erosion.
- Soil is made of organic matter/humus (dead or decaying plants and animals), rocks, minerals, water, and air.
- There are three main layers of soil: topsoil, subsoil, and bedrock.
