Key Concepts to Remember
Types of Environment
Natural (nature) + Human-made (built by people) + Human (social/cultural interaction) = Complete Environment
Four Domains
Lithosphere (land) + Hydrosphere (water) + Atmosphere (air) = Biosphere (life zone)
Ecosystem
Living organisms + Non-living surroundings + Interactions = Ecosystem (all parts interconnected)
Human-Environment Timeline
Adaptation (early) then Wheel then Agriculture then Barter then Industrial Revolution then Information Revolution
