EROSION FACTORS
• Wind
– Breaks down Rock, Rounds edges, Canyons
• Water (Moving)
– Breaks down rock and caries it away. Creates
V shaped valleys, canyons, water falls.
• Glaciers
– Scours the surface breaking down rock and
creating U shaped valleys
Wind Process
• Wind works like a sand blaster.
• Wind picks up tiny pieces of sand or dust
and blows it against rocks to carve away
the earths surface.
• Areas that have intensified winds and
large amounts of sand see the most
dramatic results
Slot Canyons SW
Moving Water Process
• As water moves it picks up sediments and
pushes them along.
• These sediments then bang in to the sides
and bottom of the river and wear it away.
• This creates features like Canyons, water
falls, and valleys.
Glacier Process
• Glaciers are made up of fallen snow that,
over many years, compresses into large,
thickened ice masses. Glaciers form when
snow remains in one location long enough
to transform into ice. What makes glaciers
unique is their ability to move. Due to
sheer mass, glaciers flow like very slow
rivers. Some glaciers are as small as
football fields, while others grow to be over
a hundred kilometers long.
Donjek Glacier in the Saint Elias Range, Yukon Territory, Canada. 1985
Glaciers occupy about 10 percent of the world's total land area

Building Processes
• Convergent Plates
– Volcanoes and Mountains
• Divergent Plates
– Rift Valleys
• Transform Plates
– Fault lines and Earthquakes
Volcanic Process-Convergent
• A Mountain has to be over 2,000 feet.
• And a volcano is formed when one plate
getting subducted under another.
• The heat melts the plate and a magma
chamber is formed.
• Then the magma escapes to the Earths
surface as Lava creating the first layer of the
volcano.

Arenal Volcano, Costa Rica
Kilauea Volcano, Hawaii.
August 2006.
Mountain Process- Convergent
• Two CONTINENTAL PLATES collide
• Both plates push up and create mountains
Rift Valley- Divergent
• When plates move apart they create a rift
valley.
• Moving apart creates a space where lava
can seep though
Fault Lines- Transform
• When two plates move side by side in
opposite directions a fault line is created.
• This area gets tremendous stress as the
rocks try to slide past each other.
• Often plates get stuck and do not move for
100’s of years until the rock breaks.
• When they do move they make up the
difference in a matter of minutes creating
Earthquakes.
