Who is responsible for outlining the principle now called uniformitarianism?

• James Hutton

• Albert Einstein

• James Hurst

• Charles Lyell

The principle of uniformitarianism states that...

• the same geologic processes have been at work throughout Earth's history

• the geologic process once at work are now changing

• Earth changes only at certain times and only after certain events.

Which of the following processes was NOT observed by Hutton when he developed the idea of uniformitarianism.

• Rivers carry rocks particles upstream

• In time, new rocks will be raised and create new landforms

• rock particles are deposited and form new layers of sediment
