Why are the lower places hotter than the higher ones if the
sun is nearer to those higher places?
Air warms as it sinks and cools as it rises. So, the temperature in a
valley is naturally warmer than the temperature on a ridge line above the
valley. Some of the warmest locations on Earth are below sea level, for
this reason (if they are inland and not near a sea like the Netherlands).
