Soil contains important nutrients for both plant and animal survival. Plants rely on soil for growth, while some animals, including humans, rely on plants for food. In addition, soil can provide shelter for animals. Soil contains living and nonliving things, and not all soil is alike. It is important for children to learn why soil it important and the ways in which humans benefit from soil.

c) rock, clay, silt, sand, and humus are components of soil; and
d) soil is a natural resource and should be conserved
Background Information from Curriculum Framework
- Soil provides support and nutrients necessary for plant growth.
- Over many years, weather, water, and living things help break down rocks to create soil. This process is called weathering.
- Rock, clay, silt, sand, and humus are all components of soil.
- Topsoil is the upper layer of soil and is a product of subsoil and bedrock.
- Subsoil and bedrock are layers below topsoil that are formed over a long period of time.
- Humus is decayed matter in soil located in the topsoil.
- Clay holds water and provides nutrients
- Sand is made of of small grains of worn-down rock.
- Silt is made up of small broken pieces of rock.
