  • Climate
    Long-term average of atmospheric conditions in a region, typically measured over years, shaping biogeography and ecosystem distribution.
  • Weather
    Short-term atmospheric conditions, including temperature, precipitation, cloud cover, and wind, often variable and unpredictable.
  • Latitude
    Imaginary horizontal lines measuring distance north or south from the equator, influencing sunlight angle and climate.
  • Equator
    Earth's midline at 0° latitude, receiving the most direct sunlight and highest energy per unit area, resulting in a hot climate.
  • Axial Tilt
    Earth's 23.5° tilt relative to its orbital plane, responsible for seasonal changes in temperature and precipitation.
  • Hadley Cell
    Large-scale atmospheric circulation between the equator and 30° latitude, creating rainforests and deserts through rising and descending air.
  • Coriolis Effect
    Deflection of moving air and objects due to Earth's rotation, curving prevailing winds and influencing ocean currents.
  • Prevailing Winds
    Consistent, long-term surface winds in a region, shaped by pressure differences and Earth's rotation.
  • Gyre
    Massive system of circulating ocean currents, transferring heat from the equator toward the poles and balancing global temperatures.
  • Specific Heat
    Property of water allowing it to resist temperature changes, stabilizing nearby land climates and moderating extremes.
  • Rain Shadow
    Dry, desert-like area on the leeward side of a mountain range, formed as moist air loses precipitation on the windward side.
  • Photosynthesis
    Process in forests converting solar energy to chemical energy and removing atmospheric carbon dioxide, contributing to climate cooling.
  • Transpiration
    Release of water vapor from plant leaves, forming clouds that block solar radiation and promote precipitation, cooling the environment.
  • Carbon Dioxide
    Greenhouse gas absorbed by water and forests, influencing Earth's heat retention and climate regulation.
  • Surface Air Pressure
    Force exerted by the atmosphere at Earth's surface, varying with latitude and driving patterns of precipitation and wind.
