- 1the atmosphereis a gaseous layer that sorrounds the earth in adition to gases he atmosphere contains solid particles in suspension it is a group of gases that we call air
- 2gases in the atmospherenitrogen 78% inert gas (does not react to other gases)
caron dioxide 0.038& produced in respiration in combustion and in volcanc erruption
water vapour and oter gases 0.97%
water vaour producen in evaporation
ozone oxygen subjaected to utraviolet radition from the sun
inert gases such as argon helium and neon
oxygen 21% produced by phoosintesis - 3structure of the atmosphereexosphere - were artifficial satellites are
thermosphere - 80 to 500 km x-rays upper part 1000 c
mesosphere - 50 to 80 km were shooting stars are temperature descends to -100
stratosphere - 12 and 15 temperature 5
troposphere - were climate phenomena occur - 4humidityis the amount of water vapour in the air
- 5air polltionis the alteration of normal composition wich can be harmfull for living thing
2 types
natural - dust in deserts or ashes
artificial - made by humans there are 2 types phisical like noise or chamical - 6acid rainpollutian gases in cloude so rai is contaminated
- 7the ozone layerit protect us from harmfull solar radiation
x-rays and gamma rays are absorbed in the mesosphere and thermosphere
ultraviolet rays in the ozone layer and in stratosphere - 8the hole in the ozone layeris not a hole is a part of it that is thinner becase of cfs
- 9effects of destroying the ozone layermain effects are
harm in skin ski cancer or prematere agning
effects on body defences infectious disises
effects on side blindness - 10water in the earth is called...hydrosphere is divided into 3 parts
solid - snow or ice
liquid - oceans seas rivers lake and groundwater
gaseous - water vapour - 11green house effectisthe phenomena by which the atmosphere retains some of the heat from the sun this regulate the temperature
- 12increse of greenhouse effectif the level of greenhouse effectincrese so thas the temperature in earth it is because humans burning fossil fules
destroying forests
this is the reason of glaobal warming - 13water in earthalmost 75% of the earth is water
97.5% of al the water is in seas or oceans
most of the fresh water is n glaciars only 0.4% of fresh water is availbe as suface water and atmospheric water is in rivers and lakes - 14growndwaterconstitues the second biggestreserve of fresh water on earth it is found under the eatrhs surface and originates from the infiltration of rainwater from melted ice or from surface water
it can acumlate in undergrond deposits,called aquifers - 15propeties of waterwater is a molecule formed by th combination of two hydrogen atoms and one oxyden atom
pure water is colourless,tasteless,odourless
at room temperature is liquid
from liquid to gas - fusion
solid to gas - sumblimation
from liquid to gas - vaporisation
gas to liquid - condesation
liquid to solid - solidificaion - 16melting point and boiling pointfrom liquid to solid 0 degrees
liquid to gas 100 dgrees - 17other properties of waterdensity of water is lower in a solid statethan in liquid state
water is the universal solvent becase it can dissolve many substanes
has a high heat capacity needs a lot of heat to increse temperature
molecules in water have a hig adhesive capacity
