Summary: After the break, we started learning about a new topic, weathering and erosion. This lesson brought make some facts and definitions from last year. Weathering is the breaking up of rocks due to exposure to the atmosphere and erosion is when weathered material is moved from one place to another. If it is weathering the material is loosened but is not moved or carried away, whereas erosion is when the material is moved away by water, wind, ice, and waves. Weathering comes in two different forms, mechanical weathering and chemical weathering. Chemical weathering is when at least some of the minerals from the rock are converted into different substances. Mechanical weathering is when rocks physically break down into pieces without the chemical makeup of the rock changing. We looked outside our classroom to find ways the weathering and erosion are taking place and to my surprise there were so many examples. One example of weathering is the plants that grow in between the cracks of concrete loosening pieces of rock. An example of erosion is the sink overflowing and dripping alongside the water fountain carrying very, very tiny pieces of rock in it. Seeing these examples really helped me understand how weathering and erosion is all around us.
SP8: Obtain, evaluate and communicate information:
I used scientific text to find important. information, evidence and ideas. I read about soil and how important it is to our lives on Soil-Net. This led me to understand how important soil is even though many people don't value it, it's one of the most important natural resources in the world. I learned that we depend on soil for food, clothing, and more. Soil contains minerals, broken down pieces of rock and organic matter. This website helped me understand the importance of soil and I will start to acknowledge it more.
