What slide is the symbol on?

Read the paragraph below from the section "What Causes Pressure?"

I had a teacher once who used to say: "You don't get something for

He meant that if air goes up in one place, it must come down in another place. That other place will be somewhere the air is not rising.

Normally, that is where the cool areas are. Cool air does not rise.

What conclusion can the reader make based on this paragraph?
