Let's solve each question in the
Global Warming Reading Comprehension Quiz based on general scientific knowledge. Since there is no accompanying reading passage, I will provide accurate answers based on common environmental science facts.

1. Name three types of fossil fuels:
Answer:
- Coal
- Oil (or petroleum)
- Natural gas
*Explanation:* Fossil fuels are formed from the remains of ancient plants and animals over millions of years. The three main types are coal, oil (petroleum), and natural gas.

2. What is the measurement of how much carbon dioxide each person adds to the environment?
Answer:
Carbon footprint
*Explanation:* A "carbon footprint" measures the total amount of greenhouse gases (especially carbon dioxide) that an individual, organization, or activity emits directly or indirectly over a period of time. It is usually measured in tons of CO₂ equivalent per year.
---
3. Name at least two greenhouse gases:
Answer:
- Carbon dioxide (CO₂)
- Methane (CH₄)
*Other possible answers:* Nitrous oxide (N₂O), Water vapor, Fluorinated gases
*Explanation:* Greenhouse gases trap heat in the atmosphere. The most significant ones include carbon dioxide, methane, nitrous oxide, and water vapor.

4. What greenhouse gas is released into the atmosphere as a result of livestock digesting their food?
Answer:
Methane (CH₄)
*Explanation:* Livestock, especially cattle, produce methane during digestion through a process called enteric fermentation. This is a major source of methane emissions.
---
5. Which greenhouse gas is produced from adding large quantities of nitrogen-based fertilizers to farmland?
Answer:
Nitrous oxide (N₂O)
*Explanation:* When nitrogen-based fertilizers are applied to soil, microbial processes convert some of the nitrogen into nitrous oxide, a potent greenhouse gas.
---
6. Which greenhouse gas is produced by either deforestation (cutting down forests or large amounts of trees) or burning fossil fuels?
Answer:
Carbon dioxide (CO₂)
*Explanation:* Trees absorb CO₂ during photosynthesis. When they are cut down or burned, the stored carbon is released back into the atmosphere as CO₂. Burning fossil fuels also releases large amounts of CO₂.
---
7. What is a large body of ice that slowly moves downhill or across the land?
Answer:
Glacier
*Explanation:* A glacier is a persistent body of dense ice that forms over many years from compacted snow. It flows slowly under its own weight, moving downhill or across the landscape.

1. Coal, Oil, Natural Gas
2. Carbon footprint
3. Carbon dioxide, Methane
4. Methane
5. Nitrous oxide
6. Carbon dioxide
7. Glacier
