it’s telling me to identify each layer and describe the three soil horizons and explain the formation and composition of each. can someone give me some websites to help? or some summaries of said websites?
IM ASKING HOW THEY ARE FORMED NOT WHAT GOES INTO THEM!!!
THIS SOOOOO DOES NOT HELP!!!!!!
There are six horizons. 1. O Horizon - The top, organic layer of soil, 2. A Horizon - The layer called topsoil, 3. E Horizon - This layer is beneath the A Horizon and above the B Horizon. It is made up mostly of sand. 4. B Horizon - Also called the subsoil - this layer is beneath the E Horizon and above the C Horizon. 5. C Horizon - it's called regolith: the layer beneath the B Horizon and above the R Horizon. 6. R Horizon - this is last and the unweathered rock layer that is beneath all the other layers.
Certainly! To identify each layer of soil and describe the three soil horizons, as well as explain their formation and composition, the following websites can provide useful information:
1. USDA Natural Resources Conservation Service (NRCS) - Soil Education:
- Website: https://www.nrcs.usda.gov/wps/portal/nrcs/main/soils/education/
- Summary: The NRCS website provides comprehensive information on soil education, including the identification and description of soil horizons. It explains the formation, composition, and characteristics of each horizon, along with visual aids such as diagrams and images.
2. Soil-Net:
- Website: https://www.soil-net.com/
- Summary: Soil-Net is an educational platform that offers resources on various aspects of soil science. It provides interactive activities and information about soil horizons, including their formation, composition, and roles within the soil profile. The website also includes videos and animations to enhance understanding.
3. Science Learning Hub:
- Website: https://www.sciencelearn.org.nz/standards/soils-and-landforms/soil-horizons
- Summary: The Science Learning Hub website focuses on providing science-related educational materials. It specifically covers soil horizons, their identification, composition, and formation. The information is presented in a concise and easy-to-understand manner, with the inclusion of diagrams and illustrations.
Remember to explore these websites and their specific sections on soil horizons to gather detailed information about each layer, their composition, and how they form.
I got this by Googling "three layers of soil".
There are three main horizons (called A, B, and C) which are present in all soil.
Organic - The organic layer (also called the humus layer) is a thick layer of plant remains such as leaves and twigs.
Topsoil - Topsoil is considered the "A" horizon. ...
Subsoil - Subsoil is considered the "B" horizon.
