    Study Notes

    Energy and Radiation

    • Energy is a measure of a system's ability to do work.
    • Energy cannot be created or destroyed, only changed in form and transferred.
    • Radiant energy travels as electromagnetic waves.
    • Solar output includes solar wind (charged gases from the sun) and auroras (light displays).
    • Solar activity can disrupt communications.

    Electromagnetic Radiation

    • Electromagnetic radiation carries energy through space or matter as electric and magnetic disturbances.
    • It can be modeled as waveforms.
    • The electromagnetic spectrum ranges from gamma rays (shortest wavelength) to radio waves (longest wavelength).
    • Wavelength is typically measured in microns (μm).
    • Different types of electromagnetic radiation include gamma rays, X-rays, ultraviolet (UV), infrared (IR), microwaves, and radio waves.
    • Wavelength and frequency are inversely related; longer wavelengths have lower frequencies.

    Radiation Principles

    • Stefan-Boltzmann Law: Hotter objects emit more radiation per unit area.
    • Net radiation is the balance between incoming and outgoing radiation, crucial for Earth's climate.

    Atmospheric Processes

    • Lapse rates describe the rate at which temperature changes with altitude.
    • Saturated Adiabatic Lapse Rate (SALR) and Moist Adiabatic Lapse Rate (MAR) vary with temperature and moisture content.
    • Dry Adiabatic Lapse Rate (DAR) is a constant rate of temperature decrease with altitude for dry air.
    • Stability conditions (stable, unstable, or conditionally unstable) depend on specific atmospheric conditions.

    Air Masses and Fronts

    • Air masses are large bodies of air with uniform temperature and humidity characteristics.
    • Air masses are classified by their source region (e.g., polar, tropical, maritime, continental).
    • Fronts are boundaries between different air masses.
    • Cold fronts, warm fronts, and stationary fronts are different types of fronts with distinct characteristics.

    Weather Elements

    • Temperature measures hotness or coldness.
    • Humidity is the amount of water vapor in the air, relative humidity is the ratio of actual water vapor to the maximum possible.
    • Pressure is the force exerted by the atmosphere.
    • Clouds are condensed water vapor in the atmosphere; different types are characterized by different appearances.
    • Precipitation is any form of water that falls from the atmosphere to the surface (rain, snow, etc.).
    • Wind is the horizontal movement of air.

    Climate and Climate Change

    • Climate is the long-term average weather conditions in a region.
    • The greenhouse effect is a natural process that warms the Earth's surface.
    • Enhanced greenhouse effect occurs due to human activities releasing greenhouse gases into the atmosphere.
    • Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and fluorinated gases.
    • Climate change impacts include rising global temperatures, sea-level rise, and extreme weather events.
    • Mitigation involves reducing greenhouse gas emissions, while adaptation involves adjusting to the effects of climate change.
    • International agreements like the Paris Agreement aim to limit global warming.

    Geomorphology

    • Fluvial processes involve the work of running water shaping the Earth's surface.
    • Key fluvial concepts include stream channel forms (straight, meandering, braided), river systems (networks of interconnected streams), and fluvial landforms (meanders, floodplains, terraces, etc.).

    Weathering Processes

    • Weathering is the breakdown of rocks and minerals at or near the Earth's surface.
    • Geomorphology is the study of landforms.
    • Endogenic processes occur within the Earth (volcanoes, earthquakes) and exogenic processes occur on the Earth's surface (weathering, mass wasting, fluvial, and glacial processes).
    • Chemical weathering is the decomposition of minerals through chemical reactions like hydrolysis and oxidation.

    Glacial Processes

    • Equilibrium line is the boundary between accumulation and ablation zones on a glacier.
    • Plucking and abrasion erode bedrock as glaciers move.
    • Moraines (terminal, lateral, and medial) are ridges of till left behind by glaciers.
    • Other glacial landforms include outwash plains, kettle lakes, and eskers.
