in an inconvenient truth, an increase in greenhouse gases is dangerous becasue
a. they trap more heat in earths atmosphere
b. they create holes in the atmopshere , releasing too much heat
c. they reduce humans ability to absorb oxagen throught their lungs
d. hey increase the power of the sun, leading to negative effects sucks as skin cance **
Cheese is just wrong
noo shut upp, guys jus include the choices and the letter thats right-
what the hell guys
No SheBop is correct
In order to accurately answer this question, let's look at each option and identify which one correctly explains why an increase in greenhouse gases is dangerous:
a. they trap more heat in earth's atmosphere
This option is the correct answer. Greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), have the ability to trap heat from the sun in the Earth's atmosphere. This process is known as the greenhouse effect. When these gases accumulate in the atmosphere at higher levels due to human activities, such as the burning of fossil fuels, the trapped heat increases. As a result, the average temperature of the Earth rises, causing various negative impacts like global warming, climate change, and extreme weather conditions.
b. they create holes in the atmosphere, releasing too much heat
This option is incorrect. Greenhouse gases do not create holes in the atmosphere. However, certain chemicals, such as halocarbons (e.g., chlorofluorocarbons or CFCs), can deplete the ozone layer, which protects the Earth from harmful ultraviolet radiation. This depletion of the ozone layer leads to increased UV radiation reaching the surface, but it is a different issue from the greenhouse effect.
c. they reduce humans' ability to absorb oxygen through their lungs
This option is incorrect. Greenhouse gases do not directly affect humans' ability to absorb oxygen through their lungs. However, an increase in greenhouse gases and the resulting climate change can indirectly impact human health by influencing air quality, causing respiratory problems, and increasing the risk of heat-related illnesses.
d. they increase the power of the sun, leading to negative effects such as skin cancer
This option is incorrect. Greenhouse gases do not increase the power of the sun. They only influence the amount of heat trapped in the Earth's atmosphere, as mentioned in option a.
In conclusion, option a, "they trap more heat in Earth's atmosphere," is the correct choice that explains why an increase in greenhouse gases, as portrayed in "An Inconvenient Truth," is dangerous.
thanks ms sue very helpful
Sorry, read the lesson and unit its for because it might be wrong but these for right for me
