global warning increases when _____ are trapperd in the atmosphere:
A)oxygen atoms
B)minerals
C)greenhouse gases
D)meltwaters
my choice is c or a
C is correct.
http://en.wikipedia.org/wiki/Greenhouse_gas
To determine the correct answer, let's evaluate each option:
A) Oxygen atoms: Oxygen atoms make up a large portion of our atmosphere, but they do not directly contribute to global warming. Therefore, oxygen atoms being trapped in the atmosphere would not lead to an increase in global warming.
B) Minerals: Minerals are naturally occurring substances and do not play a major role in global warming. Hence, trapping minerals in the atmosphere would not cause an increase in global warming.
C) Greenhouse gases: Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), are the primary contributors to global warming. These gases act like a blanket around the Earth, trapping heat and causing the planet to warm up. When greenhouse gases are trapped in the atmosphere in excessive amounts, they intensify the greenhouse effect, leading to increased global warming. Therefore, trapping greenhouse gases in the atmosphere is directly related to the rise in global temperatures. Thus, option C is correct.
D) Meltwaters: Meltwaters refer to the water released from melting ice and snow. While the melting of ice caps and glaciers is a consequence of global warming, meltwaters themselves do not directly contribute to the increase in global warming when trapped in the atmosphere.
Considering the information above, option C (greenhouse gases) is the correct choice.
