Author Holmes was brought into the science community by his interests in physics and geology .Author Holmes got a job as a prospecting job in Mozambique when he was 21 years old. Author soon became a scientist in rock study and proposed that convection occurred in the mantle. in 1919 Holmes suggested the mechanism: that the continents are carried by the flow of the mantle on which they sit, and the mantle is flowing because it is convecting. Author Holmes didn’t use a lot of modern technology since he first studied rock dating over 100 years ago. Author studied the genesis of igneous rocks, and physical geology when he studies rock dating. Arthur Holmes was a scientist who studies radiometric methods of rock dating. Arthur Holmes was born January, 14, 1890 in London England and died on September, 20, 1965 in London England. Arthur Holmes gained his early interest in Earth science at Gateshead High School entering imperial college, London in 1907. In 1910 he made a great impact upon his time through his pioneer work on radiometric methods of rock dating. His controversial views on the origins …show more content…

His first guess on the age of the Earth the first time was only 1.6 billion years old, but it changed to a more accurate figure of 4.5 billion years old. Holmes advocated cyclical expansion alternating with contraction as a means of explaining tectonic movements in the crust. Holmes became a strong supporter of A.L. Wegner’s hypothesis of drifting continents at a same time when few other geologists favored the theory. For the theory of how old the Earth is Author Holmes used the regonzation that radioactive heat was available from disintegration of uranium, thorium and potassium was shown for important implications for the thermal history of the Earth. There were 3 main lines of research to which he was to become a major contributor: geochronology, the genesis of igneous rock and physical
