Study Notes
- Charles Lyell's book "Principles of Geology" supported the theory of Uniformitarianism.
- Uniformitarianism suggested that the Earth was shaped by slow and gradual geological processes.
- This was opposed to the Catastrophism theory, which suggested that the Earth was shaped by major disasters.
- In the 19th century, various estimations of the Earth's age were made using physical models and calculations.
- These estimations ranged from tens of millions to 100 million years.
- In the 20th century, radiometric dating provided a new method for determining the age of rocks.
- The initial estimation of the Earth's age using radiometric dating was 2 billion years.
- The current estimation of the Earth's age is 4.47 billion years.
- The oldest fossils are estimated to be 3.8 billion years old.
- The new information about the Earth's age led to new theories about geological processes.
