A Changing Surface
The molding of the Earth’s crust is the product of 2 great destructive forces: weathering and erosion.
Through the combination of these processes, rocks merge, disintegrate, and join again. Living organisms,
especially plant roots and digging animals, cooperate with these geologic
processes. Once the structure of the minerals that
make up a rock is disrupted, the
minerals disintegrate and fall
to the mercy of the rain
and wind, which
erode them.
Erosion
Eolian Processes
External agents, such as water, wind, air and living beings, either acting
separately or together, wear down, and their loose fragments may be
transported. This process is known as “erosion.” In dry regions, the wind
transports grains of sand that strike and polish exposed rocks. On the coast,
wave action slowly eats away at the rocks.
The wind drags small particles
against the rocks. This wears them
down and produces new deposits
of either loess or sand depending
on the size of the particles.
Hydrologic Processes
All types of moving water slowly wear down rock surfaces and carry loose
particles away. The size of the particles that are carried away from the rock
surface depends on the volume and speed of the flowing water. Highvolume and high-velocity water can move larger particles.
Mechanical Processes
Weathering
Mechanical agents can disintegrate rocks, and chemical agents can
decompose them. Disintegration and decomposition can result from the
actions of plant roots, heat, cold, wind and acid rain. The breaking down of
rock is a slow but inexorable process.
Water
In a liquid or frozen state,
water penetrates into the
rock fissures, causing them
to expand and shatter.
A variety of forces can cause rock
fragments to break into smaller
pieces, either by acting on the
rocks directly or by transporting
rock fragments that chip away at
the rock surface.
Chemical Processes
The mineral components of
rocks are altered. They either
become new minerals or are
released in solution.

When the temperature of the air
changes significantly over a few hours,
it causes rocks to expand and contract
abruptly. The daily repetition of this
phenomenon can cause rocks to
rupture.
Transportation and
Sedimentation
In this process, materials eroded by the wind or
water are carried away and deposited at lower
elevations, and these new deposits can later turn
into other rocks.
