🔍 Key Concepts

• Cumulonimbus clouds are large thunderstorm clouds associated with strong convection • Think about the difference between vertical (up-and-down) and horizontal (side-to-side) air motion in the atmosphere • How these clouds INITIALLY form vs. what kind of weather they may later produce (like rain or storms)

💭 Think About

• Which type of air movement builds tall, towering clouds that grow upward through the atmosphere? • Do these clouds form because of rainstorms, or do rainstorms happen because of these clouds? • Is "any movement of moist air" specific enough, or do these clouds require a particular kind of motion?

✅ Before You Answer

• Focus on what starts the cloud growth, not the weather that comes after • Check which answer clearly refers to strong rising motion of warm, moist air • Eliminate choices that describe results (like storms) instead of the formation process
