Question

Why does the speaker say that mountain tops are frozen?

Answer 1

Orpheus with his lute made trees,  

And the mountain tops that freeze,  

Bow themselves when he did sing:

To his music plants and flowers  

Ever sprung; as sun and showers  

There had made a lasting spring.  

Every thing that heard him play,  

Even the billows of the sea,  

Hung their heads, and then lay by.  

In sweet music is such art,  

Killing care and grief of heart  

Fall asleep, or hearing, die.

Answer 2

temperature and pressure: When you pressurize air (or any gas), it gets hotter, and when you release the pressure on air it gets colder. ... It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level.
