hope it helps
answer A is about the Greenhouse effect though as mentioned before there are several gases involved. B and C may contribute to Global warming but that is not what the questions asks. And plants actually absorb heat when they Photosynthesize so D is actually the opposite of the truth, except in that both C and D help keep a more balanced temperature between night and day as both give off heat at night and tend to absorb heat during the day. They can also contribute to a more balanced temperature between the season as they are ore likely to give off heat during the winter and absorb more during the winter. Basically they store heat when it is warm and release it when it gets cold thereby helping create a balance.
Nope, i caused it at my house by building a glass building and putting plants in it. As for your ideas-you sound like the person who said i needed my roof replaced, you folks always try to get us elderly people roped into some scheme.
A)
Though there are also other gases such a methane that are large contributors (4x worse than CO2 I heard)...that's why some people are genuinely serious when they say we should kill all cows (apparatus cow farts contribute more to the greenhouse effect than lorries, planes and ships combined!)
Mainly effect by CO2
The official answer is A) but don't be deceived into thinking CO2 has any significant effect on Climate. Water vapour is by far snd many times the most significant Greenhouse gas,
Its actually E) People looking for power and money.
Evil people telling lies.
A) carbon dioxide and water vapor that trap heat radiating from the Earth's surface
B) heating of homes and businesses, which releases excess heat into the atmosphere
C) oceans that trap heat radiating from the Earth's seafloors
D) too many plants on the surface of the Earth, which prevents cooling of the surface
