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

Vivid Atmosphere: Tennis Slowly‚ I kneel down to tie my shoe for the fourth time this match. 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

Layers of the Atmosphere The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using... • thermal characteristics (temperature changes)‚ • chemical composition‚ • movement‚ and • density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics‚ chemical composition‚ movement‚ and density occur. Troposphere The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20

Without our atmosphere‚ there would be no life on earth. Two gases make up the bulk of the earth’s atmosphere: nitrogen (78%)‚ and oxygen (21%). Argon‚ carbon dioxide and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth

With close reference to the extract‚ show how J.B. Priestley creates mood and atmosphere for an audience here. Priestley‚ in ‘An inspector calls’‚ creates mood and atmosphere for an audience‚ in the extract‚ by using stage directions and writing how the character is talking. ‘(Bitterly)’ or ‘(with authority)’ shows that the character who is talking is talking with a certain tone in his/her voice and this makes the audience think that the person‚ who is talking‚ is trying to get the other person
