Question

fill in the blank question
air
is hot near the
and cold near the poles.

Explanation:

The sentence is about atmospheric conditions related to temperature distribution on Earth. In geography (a subfield of Natural Science), we know that air temperature (or air in general) is hot near the equator because the equator receives more direct solar radiation, and cold near the poles. So the first blank can be "temperature" (or "air" contextually, but "temperature" fits the structure) and the second blank is "equator".

Answer:

First blank: temperature (or air, but "temperature" is more precise in context); Second blank: equator
