You are hiking on a mountain trail at sunrise when you smell the smoke from cooking bacon. You can't see where the smoke is coming from. Would you expect the camp to be above you or below you on the mountain? Explain.

the camp is below you on the mountain

Explanation: Normally, this depends on the direction of the wind. Since this is not mentioned here, lets go to the smell of food. The smell of bacon indicates that there is cooking going on somewhere. This would result in heating the air around the cooking is taking place which would then naturally rises. Hot air is lighter that the air around it so it rises to the top. In an open space  like this mountain, the smell of food means that the cooking is happening below you if you can smell the cooking.

I would expect the camp to be BELOW on the mountain.

Explanation: Naturally, the smell should be dependent on the direction of the wind. But in this question, no mention of the direction of the wind was made. This leaves us to DENSITY. Hot air are typically less dense than cool air. The smoke from cooking bacon is either warm or hot. This causes the air to rise above up to the mountain top where i can perceive it. Therefore, this makes the assumption that the camp is below the mountain valid.
