Module 7: Ocean Motion

How the ocean moves is vital to climates; therefore, it is vital to life around the world. In this module, you will learn how currents, waves, and tides are formed, and how they contribute to the movement of water and energy through the oceans. You will learn the differences between surface ocean currents and deep ocean circulation, which distribute heat and drive the Earth's climate patterns. Waves are more than just water breaking on a shore. You will learn the anatomy of a wave, how they originate and move energy, and about the types of breakers, and the strength that tsunami and seismic sea waves can carry. You may have heard of high tide and low tide. You will learn more about the causes of these tides and more, including tidal characteristics and how the moon and sun contribute to tides.
