Weathering, Erosion and Deposition

Unit 3

Agenda Day 1• WHY DOES THE WORLD LOOK THE WAY

IT DOES? (SURFACES ETC)• Review weathering and Erosion–Mechanical versus chemical

• Soil as a product of erosion

• Take a walk around the neighborhood and find some evidence!

Bellwork QuizWhich of the following is a type of mechanical weathering?

A: AbrasionB: Freezing and thawingC: Plant growthD: All of the above

Weathering Poster• Each person chooses 1 picture and makes

a colored paper frame for it. • Take BLUE paper for mechanical• Take GREEN paper for chemical• Use white paper and write a SHORT

description of how it is an example of weathering.

• Put it all together on the poster!• 2 people work on the title : “Weathering in

Haeundae”

Agenda Day 2• Picture of a steep mountain: Brainstorm what

might cause sand/rocks/pebbles to go downhill? • Glue in pictures to chart• Day in the life of a piece of sediment from:

landslide, mudflow, slump, creep– Detail 1: What you are seeing– Detail 2: What you are hearing– Detail 3: What you are feeling– Detail 4: The speed at which you are falling– Detail 5: Creative detail you come up with!

Type of Mass Movement

Speed Day in the Life of a Piece of Sediment (5 details!)

Landslide + picture

fast

Mudslide + picture

fast

Slump + picture fast

Creep + picture slow

Bellwork QuizThe eroded materials carried by water or wind are called:

A: RocksB: PavementC: LandslidesD: Sediment

Agenda Day 3• Magic School bus and Analysis

questions• How did the Grand Canyon get

formed?

Bellwork QuizWhich process creates the different features of a river like valleys and waterfalls?

A: AnimalsB: ErosionC: SedimentD: Rainfall

The Grand Canyon

River Erosion

Mass Movement Erosion (Mudslides, Landslides)

How do caves form?• Cave reading (Page 80)– Write down what you think are the 3 main ideas. – Define: Groundwater, Stalactite, Stalagmite

• Sugar cube and water/vinegar activity demonstrating the formation of caves.

• Planet Earth Caves video clip and analysis questions.

Making Caves–Procedure:• Build a cube out of 27 sugar cubes. Stack 3 x 3 x 3.• Flatten a piece of clay like a pancake.• Place 15 holes in the clay with a toothpick. • Lay the clay over the sugar cubes.• Slowly drop the vinegar or warm water into the

holes.–Analysis Questions: (COMPLETE SENTENCES)• What do the sugar cubes represent?• What does the water/vinegar represent?• What does the clay represent?• How are caves formed in real life?

• Homework: Reading 96-991. How do waves form?2. How do waves erode?3. What landforms are created by wave erosion?

Bellwork QuizHow do caves form?

A. Deposition leaves layers of sediment that form caves.

B. Chemical weathering of limestone and groundwater create the caves underground

C. They are formed by earthquakes

Cave Diorama

Things to label (include):1. Limestone2. Groundwater3. Stalactite4. Stalagmite5. Glow worms6. Gypsum

H.W = wave erosion section due FRIDAY

After you finish your cave…With your partner write a 10 sentence description of HOW the cave was formed. Decorate it and glue it onto colored paper. Attach it to your cave. Include the following terms:– Groundwater– Limestone– Weathering– Erosion– Stalactite– Stalagmite– Gypsum– Sulfuric Acid– Glow worms– Carbon dioxide

Draw a river (NAME IT!) and answer the questions next to your river…

1. Explain 2 reasons HOW sediment got into your river.

2. How is kinetic energy related to your river?3. Draw pictures of large sediment in your river

and small sediment. Now explain how they move through the river differently.

4. EXPLAIN the 3 factors that affect erosion in your river.

When you are finished answer questions 1-5 on p.89

How do waves cause erosion?• P. 96-99

• Foldable! (Sea cave, sea stack, sea arch, wave-cut cliff. )• Outside flap = name and picture• Inside flap = description of how the

structure formed• Bottom = Answer the question: How does a

BEACH form?• Math skills portion : rate of beach

erosion. P.99

How does wind contribute to erosion?

• How many different sand structure can you make with “your wind?”– Cresecent-shaped dunes– Star-shaped dunes

• -Write a description of how your actions are similar to wind in real life.

• -Section assessment problems.

Bellwork Quiz• Which of the following is the major

force of erosion that shapes the coastline?

A: WindB: SunC: WavesD: Rain
