Lesson 3.1 - Location and Soil

Topography, altitude, and latitude affect climate. In addition, they also affect the type of soil in a region.  The type of soil in turn affects the types of plants that can live in an area. In turn, the plant types affect the animals in a region.  Soil can consist of clay, silt, sand, and gravel.  Basically, these are rock particles of various sizes.  Soil also consists of the remains of dead plants and animals as well as animal waste, together know as humus.  The relative abundance of each of these determines the types of plants that will thrive.  In turn, this determines the types of animals that will thrive.
