-soil is a thin layer of weathered rock, humus, air, and water
-depth, texture, and humus content of the soil determine the type of vegetation that can be supported in a region
-vegetation regions are natural environments that provide the stage for human activities such as farming, raising livestock, and producing timber
-soil, temperature, and moisture influence the type of vegetation that thrives naturally in a region
-an ecosystem is an interdependent community of plants and animals
-biomes are divided into forest, grassland, desert, and tundra
-forest lands:
broadleaf and needleleaf trees
-grasslands: flat regions with a few trees
-desert and tundra: plants are adapted to the extreme conditions their environment offers them
