Answer:
Rodney claims that shooting stars burn from entering Earth's atmosphere.
Fossil Fuels Affect the Environment in the Following Ways:
1. When we burn coal, oil, and natural gas for fuel, too much carbon enters the atmosphere at one time. The carbon combines with oxygen to form carbon dioxide (CO2), a greenhouse gas. Greenhouse gases are contributing to global warming because they trap more of the Sun's energy in the Earth's atmosphere.
2. Due to the burning of Fossil Fuels, Some Poisonous Gases like Sulphur Dioxide, Nitrous Oxide, Methane and Carbon Dioxide, Which lead to Widespread Pollution in The Atmosphere.
3. This maybe a bit Difficult. Burning of Fossil Fuels causes Acid Rain. Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
4. It also releases Radioactive Substances or Radiances which Can be Pretty Explosive.
Hope this much helps!
