Study Notes

Heat Transfer Mechanisms

Conduction: Transfer of heat through matter via particle interaction; most efficient in solids.
Convection: Heat transfer in gases and liquids driven by density differences.

Atmospheric Concepts

Coriolis Effect: Causes moving masses in a rotating system to deflect; right in the northern hemisphere, left in the southern; significant in cyclonic weather formation.
Denitrification: Converts nitrate into nitrogen gas, reducing bioavailable nitrogen in the atmosphere.
Exosphere: A thin outer layer enveloping planets or moons, where molecules are held by gravity but do not behave like gas due to low density.
Humidity: Measurement of water vapor present in the atmosphere at any given location on Earth.
Ionosphere: Atmospheric layer rich in ions and free electrons, capable of reflecting radio waves, located 50 to 600 miles above Earth.

Latitude

Defined as an angle from 0° at the Equator to 90° at the poles, impacting climate and weather patterns.

Acid Rain

Precipitation with pH lower than 5.6, resulting from pollutants like sulfur dioxide and nitrogen oxides.
Major contributors: burning fossil fuels, vehicle emissions, industrial processes.
Forms of Acid Deposition:
- Dry deposition: Acidic gases and particles fall to Earth.
- Wet deposition: Acids fall as rain, snow, or fog.

Nitrogen Cycle Processes

Nitrogen Fixation: Transforming atmospheric N2 into biologically usable forms; mainly conducted by prokaryotes, with some abiotic contributions from lightning.
Assimilation: Plant absorption of inorganic nitrogen like nitrate or ammonium from the soil for amino acid synthesis; symbiotic relationships with rhizobia aid in ammonium absorption.
Nitrification: Converts ammonia to nitrite and then nitrate; involves anammox bacteria oxidizing ammonia to produce nitrogen gas.
Ammonification: Releases inorganic nitrogen as ammonia during the decomposition of organic matter by fungi and prokaryotes.

Ozone and Ultraviolet Radiation

Ozone layer reduces harmful UV radiation; absorbs 95-99.9% of UV light.
Acid rain impacts ecosystems, and deteriorating ozone layer leads to increased UV-B exposure.
Ozone Depletion: Caused by pollutants containing bromine and chlorine, primarily from CFCs, which break down ozone in the stratosphere.
Historically, industrialized nations contributed significantly to CFC emissions.
