Explain the process of soil formation by weathering. What will be an ideal response?
Concepts to Consider: Rocks are subject to climate and organisms. Organisms produce acids that
create fissures in rock surfaces. Water seeps in, freezes, and thaws, causing cracks to enlarge and
pieces of rock to break off. Plants root in larger cracks, further breaking the rock. Slopes also cause
soil and rock to be eroded.
