Before Activity! How does soil form?
Draw a before and after picture of a piece of chalk. Place the chalk into the dish and use a tool to break into as many small pieces as you can. Before Copyright © 2010 Ryan P. Murphy

Question? Please describe in your journal how you turned your chalk into this…

Area of Focus: Weathering

The breaking of rock into smaller pieces.

Demonstration. Mechanical Weathering.
Students to observe rocks before placed in can. Teacher places several jagged small rocks into a large metal can with a lid. The can should travel around the room, each student should shake it forcefully for 5 seconds. Teacher will open the can and pour the contents out onto white paper. How have the rocks changed?

Either mechanical or chemical

Mechanical Weathering: Physically breaking rocks into smaller pieces without chemicals.

What is exfoliation in the beauty world?

“It’s when you remove dead skin cells so new healthy cells are shown.”

Sheeting or exfoliation: Rock layers peel off, fall and break apart.

Sheeting or exfolation: Rock layers peel off, fall and break apart.

Exfoliation is much like an onion losing layers.

A B Which picture best represents exfoliation?

Answer! A. A B

Answer! A. B is ice wedging.

A B Which picture best represents exfoliation?

A B Answer! B. A is Chemical Weathering.

What happens if you leave a can of soda in the freezer?

Answer! It will explode because water expands when frozen.

The increase in volume of ice is about 9%.

The increase in volume of ice is about 9%. This increase causes enough force to break most rigid containers. Copyright © 2010 Ryan P. Murphy

The increase in volume of ice is about 9%. This increase causes enough force to break most rigid containers. This is the same force, repeated on a daily basis, that creates frost heaves in the roads in the winter. Copyright © 2010 Ryan P. Murphy

Ice/Frost Wedging: Water enters cracks in the rocks, freezes, expands and breaks rocks.

Creates cracks and holds which you can use to rock climb.

What is this a picture of?

What is this a picture of?
Answer: This is a picture of the Old Man of the Mountain in Franconia Notch in the state of New Hampshire.

Draw the profile of the old man of the mountain in your journal.

Conway Granite can “rot” from weathering.

Thermal Expansion: repeated heating and cooling of rocks will induce stress and breakage.

A B Which is exfoliation, and which is thermal expansion?

Both season affect weathering.

Root Wedging: Plant roots enter a crack, grow and expand the crack.

Which picture best represent ice wedging, and which picture best represents root wedging?

A B Which is root wedging, and which is a wedgie?

B A “Ahhhhhhhh!” Root Wedging A “Urggggggggh”

Animal Activity: Animals mechanically wear away the rock.
