GEOGRAPHY

GEOLOGIST: JACKSON YATES

PRINCIPLE OF ISOSTASY

  • Isostasy says that a floating object displaces it's own weight in a liquid.
  • This applies to geography because plates float on the asthenosphere.
  • This states that mountains do not just stretch up but they also have roots that go down into the asthenosphere.
  • Examples of this is a ships hull reaching into the water.
