1. The main ingredients of soil are weathered rock
   particles, organic matter, water and air.
2. Climate affects soil by affecting the rate and
   type of weathering that forms soil. Different
   types of soil form in different climates.
   Landforms may affect soil because soil can wash
   down slopes to flatter land during and after
   rainfalls.
3. Organisms affect the characteristics of soil by
   decomposing organic matter, helping to cycle
   nutrients, mixing and loosening soil and forming
   humus as they decompose
4. The four properties of soil are texture which is
   determined by the size of weathered rock
   particles, color which is an indication of
   content and water mobility, pore space which is
   the spaces between particles and chemistry which
   is the pH of soil

Rates of Weathering

• Most weathering occurs over long periods of time
  hundreds, thousands, or even millions of years.
• There are 3 Influential factors
• Surface area
• Rock composition
• Climate

10
Surface Area

• The more of a rocks surface that is exposed to
  air and water, the faster the rock will break
  down.

11
Rock Composition

• Different kinds of rock break down at different
  rates.

12
Climate

• Chemical weathering occurs faster in hot, wet
  regions than it does in cold, dry regions.
• Mechanical weathering caused by freezing and
  thawing occurs more in cold regions than in hot
  regions.
