Study Notes
Endogenic Processes
- Endogenic processes are formed or occur beneath the Earth's surface.
- They are geological processes that originate from the interior of the Earth.
- The main Endogenic Processes are Folding and Faulting (or tectonic movements).
- Subsequent Endogenic Processes are Volcanism, Metamorphism, and Earthquakes.
- They are responsible for shaping the Earth's geological structures and the formation of mineral resources.
Folding
- Folding occurs when compressive forces push rock layers from opposite sides, causing them to bend.
- Large-scale folds are mainly found along destructive plate boundaries.
Faulting
- Faulting is the fracturing and displacement of rock strata along a fault plane caused by tension or compression.
- A fault is a break in rock where vertical or horizontal movement has occurred.
- Fault lines are often lines of weakness that allow molten rock to rise to the Earth's surface during volcanic activity.
Types of Faulting
- Normal Fault: Caused by tension, resulting in a downward displacement of the hanging wall relative to the footwall.
- Reverse Fault: Caused by compression, resulting in an upward displacement of the hanging wall relative to the footwall.
- Tear Fault: Caused by horizontal shear, resulting in a lateral displacement of the rock blocks along the fault plane.
Volcanism
- Volcanism, or magmatism, is the process of magma rising from the Earth's interior.
- Magma under pressure is released when folding and faulting create cracks or fractures in the crust.
- Magma can rise along these lines of weakness and intrude into the crust, with some reaching the surface as volcanic eruptions.
Metamorphism
- Metamorphism is the transformation of existing rock into metamorphic rock due to high pressure and heat.
- It occurs when magma intrudes into existing rock, causing changes in mineral composition and texture.
Earthquakes
- Earthquakes are sudden vibrations of the Earth's crust caused by the release of built-up strain along faults.
- They can also be triggered by the movement of molten rock within a volcano.
Exogenic Processes
- Exogenic processes are geological activities that occur on the Earth's surface.
- They are considered destructive, responsible for breaking down and reshaping the Earth's surface.
Types of Exogenic Processes
- Weathering: The breakdown of rock into smaller pieces.
- Erosion: The transportation of weathered material by wind, water, ice, and gravity.
- Mass Wasting: The downslope movement of rock and soil due to gravity.
- Sedimentation: The deposition of eroded material in new locations.
Weathering
- Physical weathering involves the physical breakdown of rock into smaller pieces.
- Chemical weathering involves the chemical alteration of rock, changing its composition.
Erosion
- Erosion by water can change coastlines, carving out valleys, and transporting sediments.
- Erosion by ice can carve out valleys, transport rock fragments, and form glacial landscapes.
- Erosion by wind can transport sand, dust, and volcanic ash, creating dunes and loess deposits.
- Erosion by gravity causes mass movement, leading to landslides, rock falls, and soil creep.
