its small gravity)‚ it has no substantial atmosphere. Its extremely thin atmosphere mostly consists of a small amount of helium and traces of sodium‚ potassium‚ and oxygen. These gases derive from the solar wind‚ radioactive decay‚ meteor impacts‚ and breakdown of Mercury’s crust. Mercury’s atmosphere is not stable and is constantly being refreshed because of its atoms escaping into space as a result of the planet’s heat. The earths atmosphere compared to mercury is much MUCH better in terms of protection

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen

The sweat creeps down my face as if mocking me in saying that I should have taken the cardio sessions more seriously. At this point I was doing everything I could just to keep my body from collapsing to the ground. The feel of the sun beating down makes me wonder if it is purposely driving all of its energy to sap mine. Glancing up across the court I see my water bottle filled with mountain dew. At that
