Question

how does the temperature of a greenhouse on the inside compare to the air temperature outside? colder hotter drier more toxic

Explanation:

Greenhouses work by trapping heat from the sun. The glass or plastic allows sunlight (short - wave radiation) to enter, which is absorbed by the plants, soil, and other objects inside. These objects then emit long - wave (infrared) radiation, but the greenhouse materials are less transparent to this long - wave radiation, so the heat gets trapped, making the inside temperature hotter than the outside air temperature. The options "colder" is incorrect as heat is trapped. "Drier" is about humidity, not temperature, and "more toxic" is irrelevant to temperature comparison.

Answer:

B. hotter (assuming the second option is labeled B, if we follow the order of options: first "colder", second "hotter", third "drier", fourth "more toxic")
