Whenever fossil fuel (coal, oil and natural gas) is burnt it releases all the carbon dioxide that has been stored up for millions of years. This CO2 adds to the greenhouse gases in the atmosphere and is causing global warming.
Fossil fuel is burnt in any transport using the combustion engine, like cars and trucks. Fossil fuel is also burnt in electricity power stations to generate electricity.
When you burn fossil fuels it releases mostly CO2 (carbon dioxide) This traps the heat that reaches the earth from the sun. That causes the greenhouse affect.
Burning fossil fuels also release Sulphur dioxide and various nitrogen oxide. When these gases mix with clouds they form dilute sulphuric acid and dilute nitric acid. That falls as acid rain.
Match the day and time of the year and location
The stars that we see on the sky change with the station of the year, they change their position depending of the day of the year and the location, mainly the latitude since on that depends what "side" of the earth the sky is facing towards, at certain points the north hemisphere sees a different sky than the south, but the east and west as long as they are in the same latitude do see the same sky.
Answer:
B. They use energy from the sun to make their own food
Photosynthesis is the process of converting sunlight to energy in a plant. The formula equation is: 6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
