Plz plz plz quick! 49 points for whoever which of the following statements about greenhouse effect is true? *life on earth is suffering because of greenhouse effect *the greenhouse effect is caused by human activity *all greenhouse gases are harmful *life on earth would not exist without the greenhouse effect
The greenhouse effect is caused by human activity
B is the right anwser, I JUSTTT too the quiz!
1- Option (D)
2- Option (A)
The green house gases plays a significant role in the earth's global temperature. In absence of green house gas, the earth would have been very much cold and life would would be difficult to exist. The average global temperature would have been about -15°C to 25°C. So the most favorable answer given here is that the earth's temperature would have decrease by about 60°C.
Carbon dioxide (CO₂) is not the most abundant green house gas. It is the second most abundant. The present composition of CO₂ in the atmosphere is about 0.04% by volume. A small increase in the CO₂ level, can lead to a global rise in the temperature. Hence, the above statement is false.
Production of electricity from nuclear energy does not produce greenhouse gases that contribute to global warming
Explanation: Nuclear energy is considered as non-renewable energy source. Although nuclear energy itself is a renewable energy source, the material used in nuclear power plants is not.
Nuclear power emits more greenhouse gases per kilowatt hour than all renewables, including biomass, hydroelectric, solar and wind. Reactors produce significantly less carbon dioxide than all fossil fuels. We can therefore conclude that Production of electricity from nuclear energy does not produce greenhouse gases that contribute to global warming.
uranium is a renewable resource
Production of electricity from nuclear energy is a lot more expensive than production of energy from fossil fuels
uranium is one of the rarest elements on earth, its more expensive than gas and oil, and it makes the same if not more pollution.
