Erosion: Mass Movements

and Wind

Objective: I can explain how
mass movement, wind, and

waves move and deposit

material

1.

Model 1 represents abrasion; model 2 represents frost wedging; and
model 3 represents Carbonation. These are all examples of
weathering that occurs on the surface of the earth. Thinking back to
the models write down a definition for weathering.

Weathering is the break down of rocks.

2. Physical weathering is the breaking up of rock into smaller particles
without changing the composition of the original rock. Which model/s that
that we completed today represent physical weathering and why (make sure
to give the scientific name)?

Model 1 – Abrasion - breaks down of the rock by bouncing against one
another and the jar. No chemical reaction takes place.

Model 2 – Frost Wedging the water just freezes and expands the
material itself does not change

3. Chemical weathering is a change in the rock that forms a new
compound and occurs on the surface of rock materials. Which model/s
that we completed today represent chemical weathering and why (make
sure to use the scientific name)?

Model 3 – Carbonation: The chalk actually dissolves in the acid which
means its composition changes.

Erosion Deposition System #1: Mass
Movements

Now that we have covered the types, causes, and results of
weathering, we can move on to the second leveling force: Erosion.
You will remember that EROSION IS THE REMOVAL AND
TRANSPORTATION OF WEATHERED ROCK BY A NATURAL AGENT.
Today you will read about the most dramatic examples of erosion called
mass movements.

Critical Thinking:

As the wind speed (velocity) increases what is going to happen to the rate
of erosion (how fast or slow erosion will occur? What will happen to the
size of the particles the wind will carry? Explain your reasoning.

Critical Thinking:

As the wind speed (velocity) increases what is going to happen to the rate
of erosion (how fast or slow erosion will occur? What will happen to the
size of the particles the wind will carry? Explain your reasoning.

As the speed increases the rate of erosion will increase and the size
of particles will also increase.
