Termini in questo insieme (16)

  • Aquatic Biome
    A large ecosystem dominated by water, defined mainly by physical and chemical factors like salt concentration.
  • Freshwater Biome
    An ecosystem with less than 0.1% salt, including lakes, rivers, and streams, making up only 3% of Earth's water.
  • Marine Biome
    A saltwater ecosystem, such as oceans, with about 3% salt, accounting for 97% of Earth's water.
  • Intertidal Zone
    A marine area between high and low tide marks, exposed to air at low tide and submerged at high tide.
  • Continental Shelf
    A submerged, gently sloping extension of a continent, ending at a steep drop-off in marine environments.
  • Neuritic Zone
    A shallow, nearshore marine region between the low tide mark and the edge of the continental shelf.
  • Littoral Zone
    A shallow, nearshore area in lakes, analogous to the neuritic zone in oceans, supporting diverse life.
  • Oceanic Zone
    A deep, offshore marine region extending beyond the continental shelf, characterized by open water.
  • Limnetic Zone
    An open water area in lakes, away from the shore, similar to the oceanic zone in marine biomes.
  • Pelagic Zone
    All open water regions in oceans or lakes, combining nearshore and offshore zones above the bottom.
  • Benthic Zone
    The entire bottom surface of a lake or ocean, regardless of depth, often rich in nutrients.
  • Photic Zone
    A sunlit surface layer in aquatic environments where enough light penetrates to support photosynthesis.
  • Aphotic Zone
    A deep, dark aquatic region where sunlight is insufficient for photosynthesis, limiting plant life.
  • Seasonal Turnover
    A process in lakes where water layers mix during spring and fall, redistributing nutrients and oxygen.
  • Ocean Upwelling
    A coastal process where deep, cold, nutrient-rich water rises to replace surface water moved by wind.
  • Thermocline
    A distinct layer in a body of water where temperature changes rapidly with depth, affecting mixing.
