Study Notes
Endogenic Processes
- Defined as geological processes that occur beneath the Earth's surface.
- Involve energy originating from the interior of the Earth.
- Characterized by continuous movement of the ground, driven by endogenic forces.
Main Endogenic Processes
- Include folding and faulting, primarily along tectonic plate boundaries.
- Shape major landforms and geological structures through movement.
Folding
- Occurs when two forces push rock layers towards each other, causing bends or folds.
- Results from compressional forces and can create large-scale folds at destructive plate boundaries.
Faulting
- Involves fracturing and displacement of brittle rock layers along fault planes.
- Creates faults where vertical or horizontal rock movements occur, often leading to volcanic activity.
- Types of faults:
- Normal fault (Convergence)
- Reverse fault (Divergence)
- Tear fault (Transform)
- Forms landforms such as block mountains and rift valleys.
Subsequent Endogenic Processes
- Include volcanism, metamorphism, and earthquakes.
- Responsible for additional geological features and processes.
Volcanism
- Describes the movement of magma due to pressure beneath the crust.
- Can result in explosive volcanic activity, with magma rising through cracks.
- Types of volcanism: intrusive (beneath surface) and extrusive (reaches surface).
Metamorphism
- Occurs under high pressure and heat, transforming existing rocks into metamorphic rocks.
Earthquakes
- Sudden vibrations in the Earth’s crust caused by plate movements and released strain.
- Can also be triggered by molten rock movements associated with volcanic activity.
Exogenic Processes
- Involves activities on Earth's surface leading to degradation and sculpting, often referred to as denudation.
Types of Exogenic Processes
- Include weathering, erosion, mass wasting, and sedimentation.
Weathering
- Breaks down rocks into smaller particles through physical or chemical processes.
- Physical weathering mechanisms: ice wedging, pressure release, plant growth, animal activity, and abrasion.
- Chemical weathering involves water, oxygen, carbon dioxide, living organisms, and acid rain.
Erosion
- Transport of weathered material driven by water, wind, ice, or gravity.
- Water erosion alters coastlines, while wind erosion shapes dunes.
Mass Wasting
- The downhill movement of rock and soil due to gravity.
- Triggers include over-steepened slopes, water saturation, earthquakes, and vegetation removal.
Classification of Mass Wasting
- Includes various forms such as slump, solifluction, earthflow, mudflow, debris slide, debris flow, rock flow, and soil creep, each with distinct characteristics and movement patterns.
Sedimentation
- Natural process where materials settle at the bottom of bodies of water, forming solids over time.
Important Considerations
- Weathered rock can remain (regolith) or be removed (sediment).
- Water is a key agent in both erosion and mass wasting, influenced by human activity as well.
