Study Notes
The Atmosphere
- The atmosphere is a complex system of gases surrounding Earth, held in place by gravity.
- It regulates temperature, climate, and weather patterns.
- It's composed of layers with unique characteristics and functions.
- Mercury, the smallest planet, lacks a thick atmosphere and experiences extreme temperature variations.
- During the day, Mercury is very hot; at night, it gets incredibly cold due to the lack of atmosphere to trap heat.
Functions of the Atmosphere
- Temperature regulation: The atmosphere traps heat from the sun (greenhouse effect), maintaining Earth's habitable temperature.
- Protection from harmful radiation: The ozone layer absorbs harmful UV radiation from the sun.
- Weather patterns: The atmosphere drives weather (rain, snow, wind, storms).
- Life support: The atmosphere contains necessary gases for life (oxygen, carbon dioxide).
Composition of the Atmosphere
- Nitrogen (N2): 78% of the atmosphere; an inactive (inert) gas that doesn't easily react with other elements.
- Needs specific conditions (lightning, high temps) for oxides to form.
- Oxygen (O2): 21% of the atmosphere; chemically active and essential for combustion, respiration, and many chemical reactions.
- Argon (Ar): 0.93%; an inert gas.
- Carbon dioxide (CO2): 0.04%; crucial for photosynthesis in plants.
- Water vapor (H2O): Percentage varies, forming clouds and rain (weather).
- Ozone (O3): Found in the stratosphere (10–55 km above the Earth's surface); absorbs harmful UV radiation. Ozone is very toxic.
Layers of the Atmosphere
- Troposphere: Lowest layer (8-18 km); contains most weather phenomena; temperature decreases with altitude.
- Stratosphere: Above the troposphere (up to 50 km); contains the ozone layer; temperature increases with altitude due to ozone absorbing UV radiation.
- Mesosphere: Above the stratosphere; coldest layer (-90°C); meteors burn up here.
- Ionosphere: Extends far above the mesosphere (~640 km); electrically charged; important for long-distance radio communication.
Atmospheric Pressure and Wind
- Atmospheric pressure is the horizontal difference in air pressure.
- Air flows from high-pressure areas to low-pressure areas, creating wind.
Weather Maps
- Graphical representations of meteorological conditions.
- Use symbols, colors, and lines to depict elements like temperature, pressure, wind, precipitation, and cloud cover.
- Isobars are lines connecting points of equal atmospheric pressure, helping to visualize high (H) and low (L) pressure areas.
Mercury Barometer
- Used to measure atmospheric pressure.
- A standard (normal) atmospheric pressure at sea level, is 101300 N/m² = 1013 millibar = 760 mm.Hg
- Vertical height difference of mercury in a barometer is representative of atmospheric pressure.
