  "id": "MLC-T-MET-003603",
  "term": "Archimedes's principle",
  "field": "Meteorology and atmospheric science",
  "definition": "A fundamental principle stating that an object wholly or partly immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object. In atmospheric science, this principle explains why lighter-than-air objects, such as hot air balloons or air parcels warmer than their surroundings, rise. The buoyant force acts opposite to the force of gravity.",
