Ocean Currents
- Ocean currents are consistent paths of moving water
- Currents carry energy and objects around the world
- Ocean currents are important for energy transfer across Earth
- The movement of water is tied to the sun’s energy
Ocean Current Patterns
- Ocean currents are not random, they follow patterns
- Ocean water flows consistently
- Ocean currents are continuous paths of water
- The paths of currents affect climate and weather
Ocean Covers Earth
- 71% of Earth is covered by ocean
- Ocean currents constantly move water throughout the world
- Ocean water carries energy from the sun
Shoes Traveling Across the Ocean
