Question

where does the energy within the greenhouse effect originate?
○ from convection within the atmosphere
○ from the circular movement of hot and cold air
○ from solar radiation entering the atmosphere
○ from the conduction of heat from the ground to the air

Explanation:

The greenhouse effect relies on incoming energy that warms the Earth's surface first. Solar radiation from the Sun enters the atmosphere, warms the planet's surface, and the re-radiated heat is trapped by greenhouse gases. The other options describe secondary heat transfer processes in the atmosphere, not the original energy source.

Answer:

from solar radiation entering the atmosphere
