FACTORS THAT EFFECT CHEMICAL WEATHERING
WATER
OXYGEN
CARBON DIOXIDE
LIVING ORGANISMS
ACID RAIN
HAPPENS WHEN ROCK IS PHYSICALLY BROKEN INTO SMALLER PIECES.
PHYSICAL WEATHERING
A KEY FACTOR IN THE CREATION OF CAVES AND CAVERNS. IT CAN ALSO HOLLOW OUT CAVES AND DAMAGE CLIFFS.
CHEMICAL WEATHERING
IS ANY DOWNSLOPE TRANSFER. THROUGH GRAVITATIONAL AND GENERALLY WATER-FACILITATED PROCESSES, OF NEAR-SURFACE SOIL AND ROCK MATERIAL.
MASS MOVEMENT
IS THE CONSTRUCTIVE PROCESS OF ACCUMULATION INTO BEDS OR IRREGULAR MASSES OF LOOSE SEDIMENT.
DEPOSITION
TWO CATEGORIES OF INTERNAL HEAT
PRIMORDIAL HEAT
RADIOACTIVE HEAT
converted the potential energy of
Earth’s constituent molecules to kinetic energy as it accreted,
initially by increasing their translational energy, thereby creating pressure.
PRIMORDIAL HEAT
the volatile decreases the rock’s melting point and they break the chemical bonds in the rock to allow melting.
Flux-induced Melting
Melting due to decrease in pressure.
Decompression Melting
is the process by which land rises out of the sea due to tectonic activity. It occurs when a great weight is removed from the land, e.g., the melting of an ice cap.
Isostatic uplift
can rise when pieces of Earth’s crust called tectonic plates move away from each other and toward
each other.
Magma (High heat and
pressure cause the
crust to melt and
rise as magma).
a mechanical movement
of the earth’s crust caused by forces that act in the crust and, primarily, mantle.
Tectonic Movement
occurs when only a portion of a solid is melted.
Partial Melting
are igneous and meta-igneous rocks with a very low silica content
Ultramatic rocks
any process that causes magma composition to change.
Magmatic differentiation
