• condensation, precipitation, infiltration, photosynthesis, transpiration, and evaporation

• up trust, precipitation, infiltration, runoff, transpiration, and evaporation

• condensation, precipitation, respiration , runoff, transpiration, and evaporation

Where is the majority of the Earth’s water found?

• The air

• The ground

• The oceans

• The rivers and lakes

What are the equations for Photosynthesis and Respiration

• 6CO₂ + 6H₂O → C₆H₁₂O₆+ 6O and C₆H₁₂O₆ + 6O₂ → 6CO2+ 6H₂O

• C₆H₁₂O₆ + 6O₂ → 6CO and 2C8 + 2502 → 16CO2 + 18H20

• 6CO₂ + 6H₂O → C₆H₁₂O₆+ 6O and 2C8 + 2502 → 16CO2 + 18H20

• 2C8 + 2502 → 16CO2 + 18H20 and C₁₂H₂₂O₁₁
