What was the main concept behind James hutton's theory?

Answer 1

James Hutton

1 Jan 1785

Used Steno's Law of Superposition. It compares rock layers to rocks above and below the rock. Evidence: Hutton found granite penetrating metaphoric schists, in a way which indicated that the granite had been molten at the time. This showed to him that granite formed from cooling of molten rock, not precipitation out of water as others at the time believed, and that the granite must be younger than the schists.

Answer 2

James Hutton didn't know about Plate Tectonics. What he did know was that the Earth is much older than people thought at the time, (mid-late 18th Century). He realised when he saw rocks formed in deep oceans, pushed onto land and folded many times, then eroded and covered with sandstones formed under desert conditions, that the Earth was older by many times more than the few thousands of years his contemporaries thought.

Answer 3

James Hutton discovered the theory of how old the earth is and formulating uniformitarianism.

Answer 4

Answer 5
