    Study Notes

    Environmental Concepts

    • Environment encompasses the total surroundings of an organism, including the physical environment, climate, and other living beings.
    • Earth's environment is divided into four interconnected spheres: lithosphere, hydrosphere, atmosphere, and biosphere.

    Spheres of the Environment

    • Lithosphere: The solid part, containing rocks, sand, soil, and minerals. Comprises about 30% of the Earth's surface, forming landmasses ranging from 10 to 50 km thick. The top layer is loose materials like gravel and soil.
    • Hydrosphere: The liquid portion, including lakes, oceans, rivers, ice, and water vapor. Covers approximately 70% of the Earth's surface; 97% is ocean water.
    • Atmosphere: The gaseous layer surrounding Earth, containing oxygen, nitrogen, carbon dioxide, and other gases. Over 99% is within 30 km of the surface. Its density decreases with altitude.
    • Biosphere: The zone where life exists on Earth's surface and in the lithosphere. Has a thin layer of a few kilometers, including plants, animals, and microorganisms.

    Interdependence

    • The spheres interact and rely on each other. For example, water, carbon dioxide, and nitrogen cycles nourish plants.
    • Organisms rely on one another for sustenance and resources.
    • Respiration and photosynthesis maintain oxygen and carbon dioxide levels.

    Ecosystem Components

    • An ecosystem is a community of organisms interacting with their physical environment, including plants, animals, and abiotic factors.
    • Ecosystem components:
      • Abiotic: Non-living factors – soil, water, gases, sunlight.
      • Biotic: Living organisms, grouped as:
        • Autotrophs (Producers): Green plants that make food through photosynthesis.
        • Heterotrophs (Consumers): Organisms relying on other organisms for food – primary (herbivores), secondary (carnivores), and tertiary (higher-level carnivores).
        • Decomposers: Microorganisms that decompose dead organic matter, releasing nutrients.

    Interdependence within Ecosystem Components

    • Abiotic factors rely on natural processes: weather, rock weathering, water cycle
    • Biotic factors are interconnected: Plants provide food; decomposition creates nutrients for plant growth; respiration provides carbon dioxide for photosynthesis; and photosynthesis provides oxygen plants use.

    Environmental Balance

    • Environmental balance depends on matter recycling and energy flow in an ecosystem.
    • Achieved through: hydrological cycle, carbon cycle, mineral nutrient cycle, nitrogen cycle, food chains, and food webs.

    Food Chains and Food Webs

    • Food Chain: A series of organisms, where each feeds on the one before.
    • Trophic Levels: Feeding stages in a food chain (e.g., producer, primary consumer, secondary consumer).
    • Food Web: A network of interconnected food chains showing energy transfer.

    Environmental Interventions

    • Natural: Processes that alter the ecosystem (e.g., droughts, volcanic activity, sea level change).
    • Human: Activities that impact the environment (e.g., deforestation, pollution, urbanization).

    Weather and Climate

    • Weather: Short-term atmospheric conditions (e.g., sunny, rainy, cloudy).
    • Climate: Long-term average weather patterns.
    • Elements: Temperature, rainfall, wind, pressure, humidity, cloud cover, sunshine.

    Factors affecting Weather and Climate

    • Latitude: Higher latitudes are cooler.
    • Altitude: Higher altitudes are cooler.
    • Distance from the sea: Coastal areas have more moderate temperatures.
    • Ocean currents: Cold currents cool coasts; warm currents warm coasts.
    • Planetary winds and pressure belts: Affect temperature and precipitation.
    • Slope and aspect: Slope influences temperature.
    • Cloud cover: Affects temperature and solar radiation.
    • Vegetation and soil: Impacts temperature and heat absorption.

    Measuring Weather Data

    • Instruments: Rain gauge, thermometer (in Stevenson Screen), wind vane, anemometer, barometer, hygrometer.

    Types of Rainfall

    • Convectional: Caused by intense heating, leading to rapid cloud formation and heavy rain.
    • Orographic (Relief): Forced uplift of moist air over mountains, leading to rainfall on the windward side.
    • Cyclonic (Frontal): Caused by the meeting of different air masses, leading to precipitation.

    Temperature Variation

    • Isotherms: Lines on maps connecting areas with the same temperature.
    • Lapse rate: Rate of temperature decrease with altitude.
    • Temperature inversion: Rate of temperature increase with altitude.

    Wind

    • Factors affecting wind: Earth's rotation, temperature differences, pressure differences.
    • Types of wind: Föhn, Sirocco, Mistral, typhoons, hurricanes, tornadoes, Harmattan.

    Pressure

    • Isobars: Lines on maps joining points with equal atmospheric pressure.
    • Pressure belts: Equatorial low, subtropical high, temperate low, polar high.

    Clouds

    • Cloud types: High (Cirrus, Cirrocumulus, Cirrostratus), Middle (Altocumulus, Altostratus), Low (Stratocumulus, Stratus, Nimbostratus), Clouds with great vertical extent (Cumulus, Cumulonimbus).

    Sunshine Measurement

    • Measures the amount of solar radiation.

    Climatic Classification Systems

    • Greek: Based on temperature (Torrid, Temperate, Frigid). Criticized for simplicity and lack of other elements.
    • Köppen: Based on temperature and precipitation, identifying different vegetation types. More sophisticated, quantitative, and useful.
