at higher altitudes the air contains more nitrogen
at higher altitudes the air is very cold
at higher altitudes, the air pressure is lower
at higher altitudes the air contains more carbon dioxide
12

18
What happens when acids in the groundwater seeps underground into limestone?
crystals can grow as the water deposits minerals on the rocks
caves can form as the acids dissolve rocks over time
molten rock can form as the chemical reactions with the acids heat the rock
sand formations can build up as the water causes abrasion of the rocks
