Answer to Question 1

ANSWER: In a greenhouse, glass allows visible radiation to enter but inhibits, to some degree, the passage of outgoing infrared radiation. For this reason, the absorption of infrared radiation from Earth by water vapor and CO2 is popularly called the greenhouse effect. However, scientific research indicates that the warm air inside a greenhouse is likely caused more by the air's inability to circulate and mix with cooler outside air, rather than by the entrapment of infrared energy. Due to these findings, some scientists suggest that the greenhouse effect should be called the atmospheric effect. To accommodate everyone, we generally use the term atmospheric greenhouse effect to describe the role that water vapor, CO2, and other greenhouse gases play in keeping Earth's mean surface temperature higher than it would be otherwise.

Answer to Question 2

ANSWER: The most important heat transport processes are likely conduction and convection. Conduction warms the air close to the soup's surface and convection moves the warm air upward. In turn, cooler air flows downward.
