Answer to Question 1

This term is a metaphor of Earth's atmosphere acting like the transparent glass cover of a greenhouse. Visible sunlight passes through the glass to strike the planet's surface. Oceans and land, like the floor of the greenhouse or the car's upholstery, reflect the incoming solar energy back as heat (invisible infrared radiation). Acting like the greenhouse glass or car windshield, Earth's atmosphere traps some of that heat.

Answer to Question 2

D
