trees
the trees produce oxygen and balance the air cycle in the nature
it can be renewed, you can split Water in half and half would be oxygen, so yes
Yes, a tank of oxygen can be half full. The oxygen would be stuck in said tank meaning no more oxygen can get in unless refueld.
yes if the oxygen is in liquid form.
because the other half of the oxygen is used for the contact stage

Oxygen was a waste product of the first organisms. They fed on the chemicals in the early sea, and spewed out oxygen, so much oxygen that oxygen replaced the carbon dioxide as an insulation layer. Plant today produce oxygen by photosynthesis.
Rainforests are the type of biome that has half of the worldâ??s species. They also produce nearly half of the worldâ??s oxygen.
Contrary to popular secular belief, tree's don't actually produce the majority of the worlds oxygen, in fact, approximately 91.6% of the worlds oxygen is produced by phytoplankton blooms in the northern hemisphere of the ocean.
IF the earth was not in the milky way then it would have had to develop in a different galaxy, this would potentially mean that the earths sphere would have a dent half its size (half life radioisotopes) and people could not live on it as there would not be enough of an ozone layer to produce enough oxygen for human beings or other living species
half of earths layer
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
Mostly due to the fact that plankton produce much of the world's oxygen.
half of earths size
