From the Gizmo video, The influence of greenhouse gases, such as carbon dioxide, on temperature is called the greenhouse effect. Based on what you’ve learned, how do greenhouse gases affect the heat flow into and out of Earth’s atmosphere? (2 points) Responses A. When greenhouse gases are high, heat flow out of the atmosphere is lower. This traps heat in the atmosphere, which raises the Earth’s temperature. A. When greenhouse gases are high, heat flow out of the atmosphere is lower. This traps heat in the atmosphere, which raises the Earth’s temperature. B. When greenhouse gases are low, heat flow out of the atmosphere is higher. This releases heat out of the atmosphere, which lowers the Earth’s temperature. B. When greenhouse gases are low, heat flow out of the atmosphere is higher. This releases heat out of the atmosphere, which lowers the Earth’s temperature. C.

Answer 1

Here are the answers to your questions based on the information provided:

1. D. carbon dioxide, CO₂ - The carbon cycle has processes that either add or subtract carbon dioxide from the atmosphere.

2. C. respiration - Animals and humans add carbon to the atmosphere through the process of respiration when we breathe out.

3. B. combustion - The process of factories burning coal and releasing carbon into the atmosphere is called combustion.

4. D. decomposition - When plants and animals die and bacteria break down their bodies, this process is referred to as decomposition.

5. B. photosynthesis - Plants remove carbon from the atmosphere through the process of photosynthesis, combining carbon dioxide with water to produce glucose and oxygen.

6. D. consumption - Carbon is transferred between plants and animals through consumption (the food chain).

7. A. increases (goes up) - Over time, the temperature on the bar graph typically increases.

8. A. Temperature gets hotter. - A maximum amount of greenhouse gas leads to increasing temperature.

9. C. 12:00 PM - Heat flow into the earth’s atmosphere is highest at 12:00 PM.

10. A. 12:00 AM - Heat flow into the earth’s atmosphere is the lowest at 12:00 AM.

11. A. Yes - Heat flow out of the earth’s atmosphere changes during the day.

12. B. 6:00 PM; 6:00 AM - The surface temperature is highest at 6:00 PM and lowest at 6:00 AM.

13. A. It reaches about 60 units, whether the greenhouse gases are high or low. - The maximum heat flow in remains about the same regardless of the level of greenhouse gases.

14. A. It reaches about 20 units, whether the greenhouse gases are high or low. - The maximum heat flow out also stays roughly the same regardless of greenhouse gas levels.

15. A. When greenhouse gases are high, heat flow out of the atmosphere is lower. This traps heat in the atmosphere, which raises the Earth’s temperature. - Greenhouse gases affect heat flow by trapping heat in the atmosphere, raising the Earth’s temperature.
