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 Quiz Which of the following is a type of mechanical weathering? A: Abrasion B: Freezing and thawing C: Plant growth D: 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!

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 How do waves form? 2.How do waves erode? 3.What landforms are created by wave erosion?

Bellwork Quiz How 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.Limestone 2.Groundwater 3.Stalactite 4.Stalagmite 5.Glow worms 6.Gypsum

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 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.
