Four Main Interconnected Systems
o Biosphere- the part of Earth’s surface where life exists (also know biota- collection of all living things that live in the biosphere)
o Hydrosphere- all earth’s water, ice, and water vapor
o Atmosphere- air blanketing Earth’s solid and liquid surface
o Geosphere- features of earth’s surface- such as continents, rocks, and the seas floor, and everything below earth’s surface.

o Look at all our to see how an ecosystem functions (soil + water = certain plant)
