4 Surface current: Wind driven current that carries ocean water horizontally across the ocean’s surface Upwelling: A vertical movement of water towards the ocean’s surface. When water is moved because of surface current, deep cold water is forced up.

5 Global Conveyor Belt: surface currents, upwelling, and density currents combine to form the great ocean conveyor belt. Variations in temperature and salinity drive this global pattern of interconnected ocean currents Answer: the coriolis effect causes the gyres in the northern hemisphere to circle clockwise

6 Weather Temperature: Measure kinetic energy of the air molecules. Low temperature means slow moving molecules. Air Pressure: When air is heated, it expands and becomes less dense. This is low pressure. Cold air means close together and dense. This is a high pressure.

8 Weather Wind speed: air moves from high pressure to low pressure.
Humidity: Heat evaporates water into the atmosphere. The amount of water vapor in the air is called humidity Precipitation: rain, snow, sleet, or hail
