Endogenic
Exogenic is a process that takes place at/or near the earth's surface.
-Atmosphere
-Hydrosphere
-Biosphere
-Weathering
-Mass Wasting
-Soil Erosion
-Physical Weathering
-Chemical Weathering
-Biotic Weathering
Refers to the combined action of an processes that cause a rock to disintegrate physically and decompose chemically because of exposure near the earth's surface.
Happens when the rocks are broken up without a chance in chemical composition.
Examples:
-Block Disintegration
-Exfoliation
-Frost Weathering
Is the breakdown of rock due to change in temperature which causes strain and stress on the rock surface joints which causes rock masses to break into small blocks.
Stripping of outer layer
of rocks due to intense heat.
The weathering process caused by cycles of freezing and thawing of water in surface pores , cracks and other openings.
Is a process by which rocks are broken down by chemical reactions, meaning there is chemical change forming a new substance
1. Oxidation
2. Carbonation
3. Hydration
4. Solution
Process by which oxygen reacts with rocks and changes its chemical composition.
Carbonation takes place when the rocks and minerals reacts with weak carbonic formed when water combines with carbon dioxide in the atmosphere.
The chemical reactions caused by water
It is the process by which the rocks are dissolved when exposed to rain water.
It is the disintegration of rocks caused by living organisms.
-Plants
-Animals
-Humans
Down slope movement of rocks,regolith, and soil because of gravity.
Fall- Free fall movement of pieces of rocks.
Slides- Rocks remains fairly concrete and more along a well-defined surface.
Flow- Rock materials are saturated with water and move down slope as a fluid.
The disintegration of rocks into particles due to natural agencies.
When winds carry a large amount of soil and sand away from region.
Removal of thin layers of soil due to surface runoff.
Removal of soil by the action of concentrated running water.
Removal of soil in water channels and drainage lines.
A Process occurring beneath the earth's surface.
Faulting
-Results of the fracture of displacement of rocks layers.
Folding
-occur when rocks are subjected to tectonic forces.
Types of Faulting:
-Tear Fault
-Strike Slip
-Normal Fault
-Reverse Fault
The eruption if molten rock called magma.
Occurs when there is pressure and heat applied to geologic structure.
A sudden shaking or vibration on the earth's surface.
