Weathering and Erosion

What is weathering?

• The process by which
  water, ice, wind or gravity
  moves fragments of rock
  and soil.
• The process by which
  water, ice, wind or gravity
  deposit rock sediments
  and soil in a new place.
• The breaking down of
  Earth’s crust into smaller
  and smaller pieces.

What is mechanical weathering?

• Process through which rocks are physically broken into smaller pieces.
• Rocks are broken down through chemical changes.
• Rocks are worn away from acid in plant roots.
• Rocks broken down by machinery.

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves
