What Is Earth System What Is Earth System Science?Science? “Tug on anything
at all and you'll find it connected
to everything else in the universe.”
-John Muir (*naturalist, writer, conservationist, and Sierra Club founder)
Earth System Science Earth System Science Defined…Defined…
How the World How the World Works!Works! • Multidiscipline science: Earth is comprised of four
closely related components: earth, water, air, and life.• Change over time: Components are continually
changing through geophysical processes and biogeochemical cycles.
• Responds to forcings from space and earth’s interior.
The The ““SphereSpheress””• Atmosphere (air, wind, greenhouse gasses, oxygen)
• Hydrosphere (oceans, rivers, groundwater, glaciers, Evian…)
• Biosphere (plants, animals, bacteria, fungi, protists…)
• Lithosphere (rocks, minerals, volcanoes, beach sand…)

Fluids have density
- Liquids are fluids
- Gases are fluids- Fire Extinguisher Activity
- Floating Bubbles Activity
- Balloon Bath
- Density Jar Observation
The AtmosphereIs made of:
Where we live…The troposphere:-- extends from surface to average of 12 km
-- temperature average 15oC at bottom to -57oC at top.
-- Density and air pressure decrease as altitude increases.
78% N220% O2
Weather is caused by:
Changes in the
• Temperature,
• Pressure &
• Humidity
of the air in our atmosphere.
