Question

1. Adriana is interested in exploring places on Earth that would not support human life, such as places with very little

oxygen. Where might she need to go to explore this type of environment?
-deep underground
-in the desert
-salt lakes
-the Antarctic

Answer 1

You can defend an answer for both salt lakes and the Antarctic. However if you have to choose one I would go with the Antarctic.

Step-by-step explanation:

There is actually more oxygen underground because the minerals of the earth is capable of storing a lot of oxygen, so the first option is not correct.

We also know that oxygen comes from plants, and that there are plenty of plants in the desert. So that should not be the correct answer either.

Now for the two that I believe could be the correct answer, the Antarctic could make sense because of its high altitude and lack of plants that cause its low oxygen levels. However, you can also say for salt lakes that since there is additional sodium ions mixed in with the water molecules, there is less available space for oxygen atoms. Therefore, there is less oxygen.
