Study Notes
Earth's Air and Ocean Currents (6th Grade)
- Uneven Heating: Earth's uneven heating is caused by the sun's rays hitting different parts of the Earth at different angles.
- Sun's Rays: The sun's rays hit the equator most directly, leading to the most intense heating.
- Convection: Convection is the circular movement of air or water caused by heating and cooling.
- Cool Air Sinks: Cool air in the atmosphere sinks because it is denser.
- Warm Air Rises: Warm air in the atmosphere rises because it is less dense.
- Trade Winds: Trade winds blow from east to west near the equator.
- Coriolis Effect: The Coriolis effect is the deflection of winds and currents due to Earth's rotation.
- Ocean Currents: Ocean currents are primarily driven by global wind patterns.
- Gyres: Gyres are large, circular ocean currents.
- Great Ocean Conveyor Belt: The Great Ocean Conveyor Belt is a global current system that takes about 1,000 years to complete a circuit.
- Landmasses: Landmasses affect wind patterns by blocking, redirecting, or channeling winds.
- Ocean Current Effects on Climate: Ocean currents can affect regional climates, creating warmer or cooler temperatures than expected for a region's latitude.
- Nutrient Distribution: Ocean currents help distribute nutrients, which are important for marine life.
- Animal Migration: Ocean currents can aid animal migration.
- Ecosystem Diversity: Ocean currents contribute to a broader variety of marine ecosystems.
- Garbage Patch: Ocean gyres can trap pollution, leading to garbage patches.
- Computer Models: Computer models are used to study air and ocean currents to predict weather, climate, and ocean conditions.
- Air Pressure Differences: Differences in air pressure are caused by uneven heating.
- Climate Change: Climate change can alter ocean temperatures and current patterns.
- Interconnected Systems: Air and ocean currents are interconnected systems that influence each other.
