Layers of the atmosphere and seasons base on ma'am dichosa

• The Earth is completely surrounded by "a sea of air" known as the atmosphere.
• Without the atmosphere life cannot exist on Earth.
• The atmosphere contains oxygen, the life sustaining gas.
• From the air, plants get carbon dioxide needed in order to live.
• The layer of air also protect us from the intense radiation by day and too much loss of heat by night.
• There is very little oxygen high up in the atmosphere so this is the reason why hikers experience difficulty in breathing when they climb high mountains.
• The most aboundant gas in the air is Nitrogen consists of 78% of the air in the atmosphere.
• Oxygen makes up about 21 % of the air
• Hydrosphere - water ex. Sea, lake
• Atmosphere - gas ex. Troposphere, stratosphere, mesosphere, thermosphere and exosphere
• Lithosphere - solid ex. Crust, mantle, and core
• ITCZ - intertropical convergence zone
• Mesosphere - have the coldest temperature of the atmosphere.
• Troposphere - most of the weather occurs.
• Thermosphere - temperature may reach as 2000 degrees Celsius.
• Stratosphere - absorb much of the Sun's harmful radiation.
• Stratosphere - contain most of the ozone layer.
• Troposphere - closest to Earth surface 10 km
• Troposphere - temperature just above the ground
• Troposphere - weather occurs
• Troposphere - turbulence occurs
• Stratosphere - 50 km above earth surface
• Stratosphere - jet aircraft can be seen
• Troposphere - clouds, mountain, airplane, air balloon.
• Stratosphere - radiosonde
• Ozone layer - O3
• Ozone layer absorbed uv radiation
• Mesosphere - between 50 km - 80 km
• Mesosphere - meteors of rock fragments
• Mesosphere - meteors
• Thermosphere - hottest
• Thermosphere - 80 km - 110 km
• Thermosphere - space shuttles, Aurora borealis and aurora australis
• Aurora borealis - northern lights
• Aurora australis - southern lights
• Exosphere - upper limit of atmosphere
• Exosphere - merges into space
• Exosphere - satellites
• Exosphere - 500km - 1000km
• The atmosphere is structured in different layers according mainly to variation in temperature.
