Q

Swell is the rise and fall of the ocean's surface due to __________.

🔍 Key Concepts

• Difference between waves and swell in terms of where they are generated • How local wind creates seas versus how energy travels after the wind stops • The idea that swell can travel long distances away from the area where it formed

💭 Think About

• Ask yourself: Does swell usually appear only right where a storm or strong wind is happening, or can it arrive on calm days from far away? • Which option best describes the source of the energy that forms swell, even when the weather over your boat is fair? • Consider how swell can reach a coast that has had no recent storms nearby—what caused it out at sea?

✅ Before You Answer

• Be clear on the difference between tides (caused by gravity of the moon and sun) and swell (caused by wave energy). • Decide whether swell is caused by conditions local to your position or by weather systems far away. • Think about whether fetch is the cause of swell itself or a factor that affects how waves grow before they become swell.
