Weather and Climate Revision:
- Weather - Day-to-day changes in atmospheric conditions.
- Climate - Averages of weather based on past years according to time of year and location.
- Troposphere - The section layer of the atmosphere.
- Intertropical Convergence Zone (ITCZ) - Where 2 sets of trade winds meet.
Jet Stream: Fast-flowing, meandering air currents in the upper atmosphere.
\
Ocean Currents:
Caused by wind, tides, water density and gravity
Distribute warmth across the
Surface Currents - move the upper 10% of water
Deep Ocean Currents - move the lower 90% of water
Thermohaline Circulation -
- Water on the surface of the ocean is cooled by the wind.
- This then sinks, as cold water is denser than warmer water
- When it sinks to the bottom of the ocean, it is heated by the Earth’s core
- This then causes it to rise
- This process continues constantly
