Students will use geographic tools to identify major landforms (e.g., continents, mountain ranges), bodies of water (e.g., oceans, major rivers) and natural resources on Earth’s surface and use relative location. CLORPT for short. Soils differ from one part of the world to another, even from one part of a backyard to another. . They differ because of where and how they formed. And over time, five major factors control how a soil forms. These factors are . Soils. We know more about the movement of celestial bodies than about the soil underfoot. . - Leonardo da Vinci.
