Explain how the Sun impacts BOTH ecosystems AND Earth systems
👉 Answer: Provides energy for food chains, drives water cycle, and creates convection currents
Explain how convection moves energy (complete answer)
👉 Answer: Warm, less dense material rises, cool, more dense material sinks, creating a cycle that transfers energy
Explain how ocean currents affect climate
👉 Answer: They move heat from one place to another, warming or cooling regions
