Answer:
If the atmospheric pressure drops it will not be able to hold up so much mercury and so the level in the barometer tube will fall. Up a mountain the air pressure is low and so the barometer reading will go down.

Answer:
Because the atmospheric pressure decreases as we go up on mountains so that's why the mercury in the barometer falls down.
