Which best explains why the temperature inside the greenhouse is higher than the temperature outside the greenhouse?

• The sun’s rays radiate heat into the greenhouse, and then the warmed air is convected inside the greenhouse.

• The sun’s rays conduct heat into the greenhouse, and then the warmed air is radiated inside the greenhouse.

• The warm air outside passes into the greenhouse by convection, and then the warm air is conducted inside the greenhouse.

• The cool air outside passes into the greenhouse by radiation, and then the cool air is conducted inside the greenhouse.
