🔍 Key Concepts

• Differences between weather-related ocean phenomena and geologic ocean phenomena • How energy is transferred through the water to create a large, long-wavelength wave • Typical causes listed in safety and seamanship manuals for tsunami warnings

💭 Think About

• Which of these choices involves a sudden movement or displacement of a large volume of water rather than just strong winds? • Think about what event usually triggers tsunami warnings in coastal areas around the Pacific Ocean. • Are tsunamis mainly associated with the atmosphere and storms, or with Earth’s crust and seafloor movement?

✅ Before You Answer

• Identify which option involves the ocean floor or earth’s crust rather than surface weather. • Ask: which phenomenon can send waves across an entire ocean basin, not just change the water level near the coast? • Eliminate choices that are primarily wind-driven effects on the ocean surface.
