So, it's homework of course and I'm sure I'll be posing a lot of these. But I really need the help, consitering I have no clue what I'm doing and I really need the A.
1. At which time of day is the heat flow entering Earth's atmosphere (Hin) highest?
A. sunrise
B. midday
C. sunset
D. midnight
2. Which of the following events could increase Earth's temperature?
A. a decrease in the relative percent of greenhouse gases
B. planting more trees
C. widespread removal of tropical forests
D. a reduction in the use of fossil fuels
3. When the levels of greenhouse gases in Earth's atmosphere increase, which statement is true?
A. Earth's temperature increases because H-in increases.
B. Earth's temperature increases because H-out increases.
C. Earth's temperature increases because H-out decreases.
D. Earth's temperature increases because H-in increases and H-out decreases.
4. Notice that a sudden change occurred at the start of Day 4 in the graph below. What change in greenhouse gases would cause this change? How would you expect temperatures to change as a result of this?

A. Temperatures are dropping because greenhouse gases are high and increasing.
B. Temperatures are dropping because greenhouse gases are high and constant.
C. Temperatures are dropping because greenhouse gases are low and constant.
D. Temperatures are dropping because greenhouse gases are low and decreasing.
