1. The correct answer is: Air pressure decreases while the amount of oxygen increases. As altitude increases in Earth's atmosphere, the air pressure decreases. This is because there is less weight of air pressing down from above. At the same time, the amount of oxygen increases because the atmosphere is thinner, so the ratio of oxygen molecules to other molecules becomes higher.

2. The correct answer is: Increase demand and use of fossil fuels. During the Industrial Revolution, there was a significant increase in the demand and use of fossil fuels such as coal, oil, and gas. These fuels release carbon dioxide and other greenhouse gases when burned, which contributes to global climate change.

3. The correct answer is: Burning trees release stored Carbon to our atmosphere. Clearing forests using fire leads to a release of stored carbon in the trees. When trees burn, carbon in the form of carbon dioxide is released into the atmosphere, contributing to the greenhouse effect and global climate change.

4. The correct answer is: Global warming. The increase in Earth's average surface temperature due to human activity is called global warming. Human activities such as burning fossil fuels, deforestation, and industrial processes release greenhouse gases into the atmosphere, trapping heat and leading to a rise in temperature.

5. The correct answer is: All weather is found here. The Troposphere is the lowest layer of Earth's atmosphere and is where all weather events occur. It is closest to the surface and extends up to approximately 10-15 kilometers (6-9 miles) above the Earth's surface.

6. The correct answer is: Cattle produce methane during digestion. Raising cattle contributes to global warming because cattle, especially cows, produce methane gas during digestion. Methane is a potent greenhouse gas that has a much stronger heat-trapping effect than carbon dioxide.

7. The correct answer is: Ozone. The Ozone layer is responsible for absorbing harmful UV radiation from the Sun. It is located in the stratosphere, which is the second layer of Earth's atmosphere, above the troposphere.

8. The correct answer is: Chemicals break down and release nitrous oxide gas, that is more than 200 times as effective in trapping heat. Nitrogen-containing fertilizers used by farmers can break down and release nitrous oxide gas, which is a potent greenhouse gas. Nitrous oxide has a much higher heat-trapping potential than carbon dioxide, contributing to global warming.

9. The correct answer is: Methane. Decomposing waste in landfills releases methane gas. Methane is a greenhouse gas that has a stronger heat-trapping effect than carbon dioxide.

10. Carbon interacts with the Earth's biosphere, lithosphere, atmosphere, and hydrosphere in various ways. In the biosphere, plants and organisms absorb carbon dioxide through photosynthesis and release oxygen. In the lithosphere, carbon is stored in the form of fossil fuels and minerals. In the atmosphere, carbon dioxide is a greenhouse gas that traps heat and affects the climate. In the hydrosphere, carbon dioxide dissolves in water and can affect the acidity of oceans.

11. The answer will require more context and research from Lesson 5.
