10 points!t. t btw its earth science 1) which has a greater mass, dry air or moist air? 2) knowing what we already know about density differences in earth systems, what do you predict the less dense air will do in relation to more dense air?

1. Moist air

2. The less dense air, the less oxygen (at least that's what my teacher says)

the answer is c) abandoned properties that are contaminated with hazardous materials.

well we can't tell you because we cant see the time give a screen shot or something.
