Our transcription: In the Eighteenth Century Scotish Geologist, James Hutton, recognized that much of the rock that composed his native land originated beneath the sea as sediment accumulating quietly on the ocean floor.
Rocks today exposed in the Earth's mountains tell us how those mountains came to be.
James Hutton, I think, was the first to make a very giant step with regards to the growth of mountains.
He found that wherever he went into the Earth's mountains, he found sedimentary rocks.
Sedimentary rocks that were formed always formed on the bottom of the ocean floor.
He realized that there had to be a connection between marine deep sea sedimentation and mountain building.
What was once on the bottom of the ocean floor was later destined to become at the tops of mountains.
