Detailed Solution
Download Solution PDFThe correct answer is - Stratigraphy
Key Points
- Stratigraphy
- It is a relative dating method, not an absolute dating method.
- Stratigraphy involves studying the layers of sediment or rock to determine the sequence of events over time.
- This method relies on the principle of superposition, where older layers are found below younger layers.
- Unlike absolute methods, it does not provide a specific numerical age but rather a relative age.
- Absolute dating methods
- Methods such as C-14 dating, palaeomagnetic dating, and thermoluminescence are used to determine the exact age of an object or layer.
- These methods are based on specific physical, chemical, or radioactive properties.
Additional Information
- Carbon-14 Dating
- An absolute dating method used for dating organic materials such as wood, bones, and shells.
- It is based on the radioactive decay of carbon-14 isotope, which has a half-life of approximately 5,730 years.
- Effective for dating materials up to about 50,000 years old.
- Palaeomagnetic Dating
- An absolute dating method that studies the Earth's magnetic field recorded in rocks and sediments.
- It helps in dating geological events by analyzing changes in the magnetic poles over time.
- Thermoluminescence
- An absolute dating method used to date ceramics, minerals, and sediments by measuring the trapped electrons released as light when heated.
- It is effective for objects dating back to 300,000 years or older.
