Study Notes
Primary Focus of Geology
- The primary focus of geology is the study of the Earth's composition, structure, and physical processes.
Relationship between Geology and Hydrology
- Geology and hydrology are closely related as they both study the Earth's water, with geology focusing on the underlying rocks and landforms that affect water flow and hydrology focusing on the water itself.
Determining Relative Ages of Rocks
- Geologists study the principles of stratigraphy, including the Law of Superposition, to determine the relative ages of rocks.
Branch of Geology for Absolute Ages
- Geochronology is the branch of geology that determines the absolute ages of rocks using techniques such as radiometric dating.
Tools for Geological History
- Geologists use various tools, including fossil records, rock sequences, and geologic maps, to chronicle the geological history of the Earth.
