Weathering & ErosionWeathering & Erosion

Blue foldable• Outside: Weathering• Inside: The break down of rock into

smaller and smaller pieces– Forms sediment– Happens to rocks that are not moving

Blue: Two Flaps

• Chemical • Mechanical or physical

Blue flap: Mechanical or Physical Weathering

• Inside:– Breakdown of rock by physical means

– Just changes the look of the rock

Blue flap: Chemical Weathering

• Inside:

– Breakdown of rock by chemical means

– Forms a new substance

Green foldable:

• Outside: Agents of Mechanical Weathering

• Inside on flaps:– Ice– Wind– Water– Gravity– Plants– Animals

On inside of Agents of weathering foldable

• Abrasion: rocks grind against each other and wear away their surface– Rocks rub together in streams– Chalk on chalkboard

• Ice: – inside: Ice wedging: water freezes in

cracks. When it expands, the crack gets bigger.

• Wind:– Inside: wind forces rocks into each other

• Water:– Inside: rivers and streams roll rocks into

each other

• Gravity:– Inside: gravity pulls rocks down into each

other• Ex: rock slide

• Plants:– Inside: roots break apart rock

• Animals:– Inside: Animals that dig break apart rocks

Pink foldable:• Outside: Agents of Chemical

Weathering• Inside on flaps:

– Water– Acid rain– Lichens– Air

• Water:– Inside: water can eat away certain types of rocks

& minerals• Acid rain:

– Inside: acids in rain causes rocks to change• Lichens:

– Inside: plants that give off acid & eat away rocks• Air:

– Inside: air causes oxidation– Oxidation: oxygen in air react with another

element to form an oxide• Creates rust

Gold foldable• Outside: Differential weathering• Inside: Process where softer, less

weather resistant rocks wears away leaving harder rock behind.

Yellow Foldable• Outside: 4 things that affect the rate of

weathering• Inside on flaps:

– Hardness of rock– Surface area exposed– Climate– Elevation

• Hardness of rock:– Inside: harder rocks weather slower than soft rocks

• Surface area exposed:– Inside: smaller rocks weather faster than larger

rocks• Climate:

– Inside: oxidation occurs more in warm, wet climates

• Elevation:– Inside: rocks at higher elevations are exposed to

more water and wind -> more weathering– Steeper mountains cause more weathering

Purple Foldable:• Outside on 1st flap: Erosion

– Inside: the transport of sediments from one place to another

• Outside on 2nd flap: Deposition-Inside: when sediments are dropped off

White Foldable:• Outside: Agents of Erosion & Deposition

• On flaps:– Water– Wind– Ice– Gravity

Water: Inside: moves sand &small rocks and deposits them in a new location

Wind:Inside: moves sand and small rocks and deposits them in new locations

Ice:

Inside: Ice moves sand and all kinds of rocks to new locations

Gravity:Inside: sediments move downhill

Salmon Foldable:• Outside: Landforms created by weathering, erosion,

& deposition

Inside labels: - Green = wind- Pink = Gravity- Yellow = Ice- Blue = Waves

Landforms made by wind• Sand Dunes

Landforms made by Gravity: rock falls, landslides
