    • A measure of water clarity: In scientific and environmental contexts, turbidity is a key indicator of water quality, measuring how much suspended material interferes with light passing through the water.
Usage Examples
  • Noun:
    • The heavy rains increased the river's turbidity, making the water look muddy.
    • Scientists measure turbidity to assess the health of an aquatic ecosystem.
    • High turbidity in drinking water can be a sign of contamination.
Advanced Usage

    • Turbidity currents on the ocean floor can carve out deep submarine canyons.

  • "Nephelometric Turbidity Unit (NTU)": The standard unit of measurement for turbidity.

    • The sample had a turbidity of 5 NTU, which is within the safe limit for drinking water.
