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
