Summary:
Soil, like air and water, is a vital resource for life on Earth. It keeps harmful chemicals out, allow plants and crops to grow on them, and clean the air. Soil takes thousands of years to form. Every 500 years, soil grows at least 1 cm thick. Soil is made up of weathered bedrock, and other materials on the surface. Other materials on the surface include sand, silt, and decomposed organisms, air water, and mineral particles. Without soil, life on earth wouldn't be possible.
SP8: Obtain, Evaluate, and Communicate Information:
This week, I obtained my information on soil through a provided website and textbooks on Earth Science. I also obtained my data by taking down notes from a video about soil. Then I used those notes to gather my data. I evaluated the validity of my data because all the sources of data was provided by the teacher. I communicated all the data I found to my team when we were working on our background research. I also communicated data on my team's background research document, showing the data I have collected.
