Answer:

Jeffrey's theory is based essentially on the history of the contraction of the earth. ... A decrease of temperature upto 400°C in the 400 km thick outer shell of the earth would cause shortening of the diameter of the earth by 20 km and the circumference by 130 km due to cooling and resultant contraction.
