Sources of Energy on the Coast

Flashcards covering sources of energy at the coast, types of waves, factors affecting wave energy, definitions of storm surges, longshore currents, and wind.

What are the primary sources of energy at the coast?

Wind, waves, tide, and earthquakes.

What are the two main types of waves?

Constructive and destructive waves.

What three main factors affect wave energy?

Fetch, strength of the wind, and duration.

What causes a storm surge?

A bulge in the ocean surface caused by low pressure and strong winds (rising air) blowing towards the center of a storm.

What is a longshore current?

A current that follows the direction of longshore drift, moving parallel to the beach.
