Waves - Mechanical energy can be transferred when objects push or pull on each other over a distance. Mechanical and electromagnetic waves transfer energy when they interact with matter. Thermal energy can be transferred through radiation, convection and conduction. An electrical circuit transfers energy from a source to a device.

Heat Transfer - Thermal-energy transfers in the ocean and the atmosphere contribute to the formation of currents, which influence global climate patterns. Energy can be transferred through a variety of ways. Energy can be transformed or transferred but is never lost.

Water Cycle - The hydrologic cycle illustrates the changing states of water as it moves through the lithosphere, biosphere, hydrosphere and atmosphere. Thermal-energy transfers in the ocean and the atmosphere contribute to the formation of currents, which influence global climate patterns
