Study Notes
Running Water and Groundwater
- Water constantly moves between oceans, atmosphere, Earth's surface, and the biosphere.
- Processes: Precipitation, evaporation, infiltration (water into rock/soil), runoff, transpiration (plants releasing water into the atmosphere). Water transport depends on velocity.
- Gradient: The slope of a stream channel.
- Stream Channel: The path water follows.
- Discharge: The volume of water flowing past a point in a given time.
- Tributary: A stream emptying into another stream.
- Meanders: Winding stream course in broad valleys, near base level.
- Bedload: Material too large to be carried in suspension.
- Capacity: The maximum load a stream can carry.
- Deposition: Occurs when stream flow is below settling velocity. Deposits are called alluvium.
- Deltas: Sediment accumulation where a stream meets a lake/ocean.
- Natural Levees: Parallel streams and contain water except during floods.
- Narrow V-shaped valleys: Stream's primary work is downcutting toward base level. Features include rapids and waterfalls.
- Floodplains: A wide area of a valley covered by water during floods. Meanders, cutoff, and oxbow lakes often form.
- Floods: Event when stream discharge exceeds channel capacity causing overflow.
- Drainage Basin: Land area contributing water to a stream.
- Divide: Imaginary line separating drainage basins.
- Zone of Saturation: Area where water fills all open spaces in sediment/rock.
- Groundwater: Water within the zone of saturation.
- Water Table: Upper boundary of the saturation zone.
- Porosity: Percentage of pore space.
Glaciers
- Glaciers: Thick ice masses that form over hundreds/thousands of years.
- Ice Ages: Periods with widespread glacial coverage.
- Valley Glaciers: Ice masses flowing down mountain valleys.
- Ice Sheets: Massive ice masses covering large regions.
- Flow: Movement caused by plastic flow (movement within ice) and basal slip (sliding).
- Erosion: Glaciers erode through plucking (lifting rocks) and abrasion (wearing away rocks).
- Glacial Trough: U-shaped valley formed by glacial erosion, originally a V-shaped valley.
- Cirque: Bowl-shaped depression at the head of a glacial valley.
- Arêtes and Horns: Sharp ridges and peaks resulting from glacial erosion.
- Till: Material deposited directly by a glacier.
- Stratified Drift: Sediment deposited by meltwater.
- Moraines: Layers/ridges of till.
- Outwash Plains: Sloping plains from meltwater streams.
- Kettle: Depression created when a block of ice melts within glacial deposits.
- Drumlins: Streamlined, asymmetrical hills of glacial debris.
- Eskers: Ridges of sand and gravel deposited by streams beneath glaciers.
Deserts and Wind
- Abrasion: Windborne particles wearing down rock.
- Loess: Deposits of windblown silt, extensive layers.
- Dunes: Wind-accumulated sand mounds/ridges.
- Types of Sand Dunes: Barchan, transverse, longitudinal, star, parabolic, barchanoid.
- Deflation: Removal of fine sediment by wind.
- Desert Pavement: Layer of coarse pebbles/gravel remaining after wind removes finer material.
- Playa Lakes: Flat areas that fill with water after rain.
- Alluvial Fans: Fan-shaped deposits of sediment where a stream slope abruptly reduces.
Earthquakes and Earth's Interior
- Earthquake: Vibration of Earth from energy release.
- Focus: Point within Earth where the earthquake originates.
- Epicenter: Point on the surface located directly above the focus.
- Faults: Fractures in Earth where movement has occurred.
- Aftershocks: Smaller earthquakes following a main earthquake.
- Foreshocks: Small earthquakes preceding a major earthquake.
- Seismographs: Instruments to record earthquake waves.
- Surface Waves: Seismic waves that travel along Earth's surface.
- Body Waves: Seismic waves that travel through Earth's interior.
- P Waves: Push-pull waves that compress/expand.
- S Waves: Seismic waves that travel along Earth's outer layer.
- Shadow Zones: Regions where body waves are not detected because they are absorbed or reflected in the Earth's core.
- Richter Scale: Measures earthquake amplitude (magnitude).
- Moment Magnitude: Measures energy released by earthquakes (more widely used).
- Continental crust: Upper crust composed of granite.
- Oceanic crust: Upper crust composed of basalt.
- Lithosphere: Crust and uppermost mantle (cool, rigid, solid).
- Asthenosphere: Upper mantle, soft and easily deformed
- Lower mantle: More rigid, rocks flow gradually.
- Outer Core: Liquid layer
- Inner core: Solid sphere
- Mohorovicic discontinuity (Moho): Boundary between crust and mantle.
