3. When the Moon is in the position shown, how would the Moon look to an observer on the North Pole?

could you maybe show a picture of what ur describing?

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
