Geologic+Time+Slides
Estimated Age: 4.6 billion years old.
Formation: Represents the formation of Earth, Sun, and other planets.
Dating Methods:
Radioactive dating of meteorites, moon rocks, and oldest Earth rocks.
Humanity's Span: Very minuscule compared to Earth's age, referred to as "deep time" or "geologic time."
Zircon Crystals (Australia) - found to be 4.4 billion years.
Acasta Gneiss (Canada) - 4.03 billion years.
Isua (Greenland) - 3.7 - 3.8 billion years.
Meteorites:
Canyon Diablo (Arizona) - 4.54 billion years.
Allende (Mexico) - 4.567 billion years.
Moon Rocks:
Apollo 15 (Genesis) - 4.1 billion years.
James Hutton: Proposed Uniformitarianism, suggesting that processes observed today happened similarly in the past, indicating Earth's age is much older than previously thought.
Biblical Chronology: Bishop Ussher estimated Earth's age at 6000 years.
Scientific Estimates:
DeBufon (75,000 years); Kelvin (98 million years); Darwin (300 million years); Halley (100 million years); Lyell (240 million years).
Relative Dating: Determining the sequence of events but not exact ages.
Absolute Dating: Establishing the actual age of events in years.
Steno’s Laws: Key principles for relative dating (e.g., Law of Superposition, Original Horizontality, Cross-Cutting Relationships).
Definition: Interruptions in the rock record indicating periods of erosion and missing deposition.
Types: Angular unconformity, Disconformity, Nonconformity.
Fossils: Remains or traces of prehistoric life, crucial for understanding ancient climates and relative dating (Fossil Succession).
Darwin's Theory: Proposed that life forms evolve through natural selection, adapting to their environments over vast time periods.
DNA Evidence: Foundation for modern evolutionary theory, illustrating shared ancestry among living organisms.
The study of Earth's age incorporates scientific methods across geology and biology, linking fossil records, radiometric dating, and evolution to provide a comprehensive understanding of the planet's history.
