Study Notes
Introduction to Geology
- Geology is the study of the origin, occurrence, distribution, and usage of materials (metallic, non-metallic, inorganic), minerals, rocks, sediments, soils, water, oil, and other inorganic natural resources.
Branches of Geology
- Structural Geology: Focuses on the configuration of rocks within the Earth's crust.
- Geomorphology: Studies the formation and evolution of landforms and bathymetric features.
- Crystallography: Examines the external forms and internal atomic structure of crystalline materials.
- Petrology: Studies rocks, including their composition, texture, structure, occurrence, distribution, and origin.
- Stratigraphy: Describes and classifies sedimentary rock layers and interprets their environments of formation.
- Paleontology: The study of fossils and how they can provide information on past organisms and environments.
- Hydrogeology: Focuses on the distribution, movement, and occurrence of groundwater within the Earth's crust.
- Seismology: Studies the Earth's structure through seismic waves, and surface deformations during earthquakes.
- Geochemistry: Studies the chemical composition of the Earth's crust and oceans.
- Mining Geology: Applies geological knowledge to develop mineral resources.
- Spectral Geology: Measures and analyzes the electromagnetic spectrum to identify rock types.
- Marine Surveying: Investigates the ocean floor's processes and features.
- Mineralogy: Studies the characteristics of minerals.
- Geophysics: Examines the Earth's physical structure, conditions, and evolution.
- Physical Geology: Focuses on geological processes that create landforms and change Earth's surface.
- Engineering Geology: Applies geological knowledge to civil engineering.
- Geodesy: Studies Earth's shapes and dimensions.
- Historical Geology: Reconstructs past geological history
- Oceanography: Studies the composition, motion, and processes responsible for ocean water.
- Sedimentology: Studies sediment grains to understand their formation and distribution.
Compositional Layers of the Earth
- Crust: The outermost rocky layer (0-100 km).
- Mantle: Layer between crust and outer core (100-2900 km).
- Core: Innermost layer (2900-6370 km).
Mechanical Layers of the Earth
- Lithosphere: The rigid outer layer, made of the crust and upper mantle.
- Asthenosphere: The soft, plastic layer of the mantle that allows tectonic plates to move.
- Mesosphere: The strong, lower part of the mantle.
- Outer Core: A liquid layer composed of iron and nickel.
- Inner Core: A solid sphere of iron and nickel.
Plate Tectonics
- Plate tectonics is the theory that Earth's lithosphere is divided into plates that move constantly, causing earthquakes and creating mountain ranges, volcanoes, and continents.
- Boundaries: Divergent, convergent (ocean-ocean, ocean-continent, continent-continent), and transform.
Weathering
- Weathering is the breakdown of rocks into smaller pieces.
- Includes physical weathering (e.g., frost wedging, thermal expansion) and chemical weathering (e.g., dissolution, oxidation).
Erosion
- Erosion is the transportation of weathered material by natural forces (wind, water, ice).
- Erosion is directly related to weathering and deposition.
Geological Works of Wind
- Wind can erode, transport, and deposit sediment.
- Methods include deflation, abrasion, and attrition.
Geological Works of Water
- Water can erode, transport, and deposit sediment.
- Includes erosion by rivers, waves, glaciers, and oceans.
Geological Works of Lakes
- Lakes are accumulations of water that are characterized by many variables (depth, shape, water quality elements)
- Lakes are caused by glacial activity, tectonic movements, meteorite hits, and river courses.
Geological Works of Oceans
- The ocean influences Earth's climate through currents and wind patterns.
- The ocean acts as a major reservoir for water and nutrients.
