Natural forces that influence the shape and structure of the planet
Geologic Processes
2 categories of Geologic Process
Exogenous and Endogenous
this geologic process occur on or near the surface of the earth
Exogenous Process
this are natural occurrences that leave significant changes on landscape
Exogenous Process
Enumerate atleast 2 exogenous process
Weathering; Mass Wasting; Erosion; Sedimentation
this is the breaking down of rocks through contact with Earth’s atmosphere, water, and biological organisms
Weathering
Enumerate the effects of weathering
- loss of atom and molecules from weathered surfaces
- addition of specific atoms to the weathered surface
- breakdown of one mass into two or more masses
Enumerate the types of weathering
physical weathering; chemical weathering; biological weathering
the breakdown of rocks by mechanical forces concentrated along rock features
Physical Weathering
this type of weathering occurs in high temperature
chemical weathering
the breakdown of rock caused by its reaction to water
hydrolysis
when acidic water produce clay and soluble salts
hydrolysis
soluble materials in rock are dissolved by water
dissolution
this weathering happens when rocks are worn out away by living organisms
biological weathering
this is the repeated cooling and heating
Thermal expansion
2 main reason why the interior of the Earth is very hot
Primordial Heat and Radiogenic Heat
the internal heat energy accumulated by dissipation
primordial heat
this heat is the result of spontaneous nuclear disintegration
Radiogenic heat
this refers to the heat energy that existed in the early universe
primordial heat
this process is caused by force from within the interior of the Earth
endogenous processes
is process is responsible for earthquake, development of continents, mountain building, and volcanic activities
endogenous processes
this is the formation of magma
magmatism
these are molten rock materials
magma
this is the eruption of molten rock from inside the earth to the surface
volcanism
