• Trapping heat
• Generating new energy

Which factor determines the amount of solar radiation an area receives?

• Atmospheric pressure
• Earth's tilt and orbit
• Ocean currents
• Volcanic activity

What does 'albedo' refer to in the context of solar radiation?

• Heat absorption
• Light reflection
• Energy generation
• Radiation blocking

How do ecosystems primarily benefit from solar radiation?

• By blocking UV light
