Water Cycle
the cooling process by which a gas changes back into a liquid
condensation
Substances that are needed for survival
Nutrients
day to day changes in the atmosphere

Northern hemisphere: clockwise
Southern hemisphere: counterclockwise
What causes surface currents and what causes deep currents? (hint: there are two answers)
Surface currents: wind
Deep currents: density differences
