Answer 1

Answer:

Atmospheric pressure come from air above it as gravity pulls it to Earth

In the earths atmosphere, pressure, which is related to the number of molecules per unit volume, decreases exponentially with altitude. Thus, if a parcel of air from the surface rises (because of wind flowing up the side of a mountain, for example), it undergoes an expansion, from higher to lower pressure

As atmospheric pressure rises, airfrom active areas of the mine will tend to migrate toward sealed areas and into gobs, introducing oxygen into those areas of the mine
