Mufu Mountain in Pingjiang County, an old revolutionary base, is more than a thousand meters higher than Yueyang City. Compared with Yueyang City, the atmospheric pressure at the top of Mufu Mountain is ______ (fill in "higher"

Mufu Mountain is higher than Yueyang City. The higher the altitude, the lower the atmospheric pressure. Therefore, compared with Yueyang City, the atmospheric pressure at the top of Mufu Mountain is lower.

There are many applications of atmospheric pressure in life, such as sucking drinks through straws, sucking hooks on suction cups, sucking medicinal liquids from syringes, sucking ink with pens, and pumping water with water pumps, etc., all of which use atmospheric pressure to work.

So the answer is: lower; the water pump uses atmospheric pressure to press water from low to high.
