Actual exam question for WGU's WGU Integrated Physical Sciences (MTC1) exam

Question #: 5
Topic #: 3

[All WGU Integrated Physical Sciences (MTC1) Questions]

Which of these is an example of climate change caused by human activity?

AWeather changes from regularly repeating atmospheric conditions such as El Nino

BWorldwide weather changes from changes in the flow of air currents

CYear to year differences in snowfall in a given area from different weather patterns

DWarming because of farming and fuel use adding nitrous oxide to the atmosphere

Show Suggested Answer

Suggested Answer: D

Human activities, such as farming and the burning of fossil fuels, release greenhouse gases, including nitrous oxide, into the atmosphere. These gases trap heat and contribute to global warming and climate change. Unlike natural variability in weather patterns, human-induced climate change is characterized by long-term changes in temperature, precipitation patterns, and other climatic factors due to increased concentrations of greenhouse gases.

C is about clouds, not really human activity. D is clear.

I’m a bit confused. Aren’t A, B, and C more about natural weather changes? I think D is the only one that mentions human influence directly.

I'm not completely sure, but I remember something about how methane is a greenhouse gas. Does that make D the best choice?

I feel pretty good about this one. The question is asking for an example of climate change due to human activity, and methane from farming is a major contributor to that. I'm going to go with option D.

Okay, let's see. I know that changes in temperature from weather patterns like cold fronts or wind direction wouldn't be considered climate change caused by humans. And increased cloud cover affecting temperature is more of a weather phenomenon. I'm leaning towards D as the best answer here.

Hmm, I'm not totally sure about this one. I know climate change can be caused by human activities, but I'm not confident which of these options would be the best example. I might need to think it through a bit more.
