  "id": "MLC-T-MET-003843",
  "term": "Base level of erosion",
  "field": "Meteorology and atmospheric science",
  "definition": "The lowest elevation to which a river or stream can erode its channel. The ultimate base level for all river systems is global sea level, as water cannot flow downhill below this point. Local base levels can be established by lakes, reservoirs, or resistant rock layers that temporarily halt downward erosion.",
