interaction between organisms and their environment. In this Lesson,
well explore the environmental factors that affect living things.
Well look at the physical
factors that shape the environment: temperature, wind, the
availability of water, and the makeup of rocks and soil. Then well
investigate the worlds climate regions and see how altitude
affects local weather conditions.
Our planet is divided into nine
major terrestrial biomes, from the driest deserts to the humid
rainforests. Well look at all these habitats and learn about
