Fossil fuels are used to generate most of the electricity used on Earth. But where do they come from? Watch this video to gain a better understanding of the natural processes that create fossil fuels. Now that you know a little bit about where fossil fuels come from, can you explain how the Sun’s light energy is ultimately responsible for the energy in fossil fuels? Describe the path that light energy must take to become the chemical energy in fossil fuels and then electrical energy. (Hint: Think about how plants in an ecosystem get their energy.)

Now that you see to some extent bit about place nonrenewable fuel sources come from, can you analyze in what way or manner the Sun’s light strength is ultimately being the reason for the strength in fossil fuels? Describe the way that light strength must enjoy become the synthetic strength in fossil fuels and therefore energetic energy. (Hint: Think about by means of what plants in an environment take their energy.)

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
