How the atmosphere has changed over time concentration of gases changes because of photosynthesis and respiration
Three aspects that support life on Earth temperature, water, and oxygen in the atmosphere
Tectonic plates most active region on Earth, collisions form mountains
Erosion effects mountains, rocks, soil, removal and transportation of surface material
Producers plants
Atmosphere thin layer of gases around the Earth, caused by gravity
Stratosphere location of ozone
Troposphere most dense layer due to gravity, temperature and pressure decrease with altitude
Energy transfer Earth is an open system
Convection air that is constantly in motion
Conduction transfer due to direct contact
Parts of the Earth core, crust, mantle
Inner core 4,000 to 5,000 degrees Celsius
Open system matter and energy are exchanged with surrounding environment
Richter scale magnitude of earthquake
Magma molten rock in upper mantle
Greenhouse effect keeps the earth warm enough for life
Hydrosphere all of the water at or near the earth’s surface
Freshwater mostly in ice caps and glaciers
Ocean more salt
Salinity measure of dissolved salts
Deep currents flow along ocean floor
Surface currents depend on hemisphere, wind driven, influence climates
Deep zone bottom of thermocline to bottom of ocean
Biosphere where all organisms can obtain energy
Matter earth is a closed system
