How do plants contribute to the formation of soil? Plants -

• cover the soil and shade it from sunlight.

• die, decompose and become part of the soil.

• use soil to grow and develop over time.

• support the animal life in the soil.

A student made a mixture of sand, tiny rocks, small twigs, and some leaves. This student has modeled

• How rocks change over time

• the life cycles of plants.

• the formation of soil.

• how landforms are created.

A student exploring the formation of soil put rocks in a plastic jar of water and shook it. Afterwards, there were small pieces of broken rock in the water. What process in the formation of soil does this model?

• Weathering of earth materials

• Decay of plant matter

• Formation of various minerals

• Mixing of water and air
