Question

Question 18 4 pts James Hutton theorized that subterranean heat, as evidenced by the existence of hot springs and volcanoes, would cause the chemical reactions that created formations of basalt, granite, and mineral veins. He also proposed that internal heat causes the crust to warm and expand, resulting in the uplift that form mountains. The same process would causes rock layers to tilt, fold and deform, as shown by the angular unconformity he saw at Siccar Point in Scotland. How does Hutton's 18th Century "heat engine" model of the Earth relate to the modern plate tectonic model? HTML Editor Paragraph 12pt 0 words

Answer 1

The only way where James Hutton concept can be used on the plate tectonics model is by using his idea of internal heat which is used to make the asthenosphere into semi solid state and thus flow with very slow velocity (creep is the word used for such slow speed) and this asthenosphere applies drag force on the lithospheric plate which causes these plates to move.
