Which latitdes have the both warmest and coldest temps?

Answer 1

The sun's apparent movement(between north and south) is limited between the tropic of cancer and the tropic of capricon.The sun shines overhead here and beyond this towards poles, the sun will be shining in an inclined angle only. Further, these are the nearest latitudes to the poles over which sun shines overhead.So most probably these two latitudes may have both warmest and coldest temperatures.The difference between the maximum temperature and minimum temperature either in a day or in a year will be maximum only over these latitudes .

Answer 2

The middle lattitudes that are over land masses. The Central US can get well below zero, yet get over 110 degrees in the summer sometimes. land areas have much more variable air temperatures than oceans. The tropics rarely get cold and the arctic rarely gets hot, so they do not have the extremes that the middle lattitudes (25 to 60 degrees).

Oops, did you mean which ones have just the coldest and which has the hottest??? LOL. Wait! Reverse that. LOL.
The tropics which usually range from 0 to 25 degrees (North and South) are usually the hottest and the Arctic/Antarctic which usually are considered 60 degrees to 90 degrees (the poles) are the coldest. The part about land areas are important too.
