Explanation:

When solar radiation reaches Earth, about 20 percent is absorbed by the atmosphere and clouds, 30 percent is reflected into space by Earth's surface, the atmosphere, or clouds, and 50 percent is absorbed directly or indirectly by Earth's surface and keeps Earth's surface warm. The option "50 percent is reflected directly or indirectly by Earth's surface and keeps Earth's surface warm" is incorrect because reflection does not keep the surface warm; absorption does.

Answer:

• 20 percent is absorbed by the atmosphere and clouds
• 30 percent is reflected into space by Earth’s surface, the atmosphere, or clouds
• 50 percent is absorbed directly or indirectly by Earth’s surface and keeps Earth’s surface warm
