Which of the following are examples of the effects of living things on the atmosphere and climate?

outgassing of volcanoes
the buildup of oxygen in the atmosphere
mass extinctions
changes in levels of carbon dioxide

The build up of oxygen in the atmosphere and changes in the levels of carbon dioxide. Brainest please.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
