Rock Cycle
The process by which the 3
main rock types (metamorphic,
igneous, and sedimentary) go
through a process to transform
from one type to another
“The rock chain”
Igneous
a type of rock that forms from
the cooling and solidification of
molten rock (magma or lava)
either beneath the Earth's
surface (intrusive or plutonic)
or on the surface (extrusive or
volcanic).
Sedimentary
rocks formed on or near the
Earth's surface from the
accumulation, deposition, and
lithification of sediments
Metamorphic
a type of rock formed when
pre-existing igneous,
sedimentary, or even other
metamorphic rocks are
transformed by intense heat
and pressure deep within the
Earth's crust, without melting.
Physical
Weathering
the process of breaking rocks
into smaller pieces through
mechanical forces, such as ice,
wind, or temperature changes,
without altering their chemical
composition.
Chemical
Weathering
The process where chemical
reactions break down rocks,
transforming their minerals into
new substances, often
weakening them and making
them more susceptible to
erosion.
weathering
the in-place breakdown of
rocks, soils, and minerals
through contact with the
Earth's atmosphere, biota
(living things), and waters,
without significant movement of
the broken pieces.
erosion
The wearing away and removal
of earth's surface
materials—such as soil, rock,
and sand—by natural forces
like water, wind, or ice.
Mass wasting
/ mass
movement
the downslope movement of
soil and rock under the sole
influence of gravity.
foliation
The alignment of mineral grains
or structural features in a
metamorphic rock, forming a
layered or sheet-like texture,
similar to the leaves of a plant.
sediment
solid material, like soil and rock
fragments, that settles at the
bottom of a liquid.
deposition
a physical process where a gas
transitions directly into a solid
geohazard
any geological process or
phenomenon, whether natural or
human-made, that poses a threat
to people, infrastructure, or
property.
