Weathering/Erosion/Deposition

V-Map 1 side for chalk 1 side for m&m’s

Do Now SWBAT describe mechanical weathering 1. Where do pebbles and small particles of rock come from? 2. Did anyone carve pumpkins this weekend?

V-Map 1. Pretend the whiteboard is a piece of paper. 2. Copy the V-Map on the whiteboard down on to your paper. COPY IT EXACTLY AS IT IS ON THE BOARD. Mechanical weathering is breaking down of rocks into smaller pieces without changing what the rock is. Kind of like carving a pumpkin. I can carve the pumpkin, which makes smaller pieces, but it still is a pumpkin.

Mechanical Weathering Hypothesis- make a prediction using no personal pronouns using an If, Then, Because statement. You are going to weather your rock for 5 million years. 1. What will happen to an M&M if it is mechanically weathered? If__________ then___________ because________________

Procedures 1. Make observations about the M&M in your data table 2. Choose an M&M of your own- your favorite 3. Take the M&M’s, and place them into the plastic container 4. Shake the plastic container for 5 minutes 5. (A or 1 is the timer for your group) Initial Observations Color, size, shape, texture Color Size (Cm) Shape Texture Drawing Observations after the experiment

Weathering/Erosion/Deposition Foldable 1. Create a foldable by following the directions given to you on the sheet 2. Use the example on the board to help you make your foldable 3. Use the books to fill out your flipchart Ch. 4 (pgs. 115 -120) Weathering (work on this today) Ch. 5 (pgs. 145 -170) Erosion and Deposition

Conclusion M&M’s 1. What happened to the M&M’s 2. Thinking of the rock cycle, what process did you perform, and what would need to happen next for your m&m to become a rock? 3. Of the 4 mechanical weathering processes, which did you demonstrate during the lab? EXPLAIN. 4. How do you think this might happen in the natural world? (mechanical weathering examples)

Exit Ticket 1. What is mechanical weathering? 2. What ways can mechanical weathering occur? 3. Which of the 4 ways of mechanical weathering did you demonstrate in the lab, why?

Do Now SWBAT explain chemical weathering processes 1. Make a prediction by writing a hypothesis in an if-then-because statement using no personal pronouns. What will happen to the fire if Mr. Wallace places Boric Acid into the flame? (or universal indicator solution)

Cleopatra’s Needle Cleopatra’s needle is an ancient stone monument made in Egypt during the time of the Pharaohs. This monument was moved from Egypt to New York City in 1881. Over time it’s surface has been exposed to weathering processes, both chemical and physical, and it has been a challenge to keep it in good condition. The type of stone reacts with acidic solutions easily which has caused it to weather away. Think-Pair-Share 1. How does the monument get exposed to acidic solutions (liquids)? 2. How do you think the amount of surface area a rock has affects how fast or slow it will weather?

V-Map Chemical weathering is the breaking down of rocks that changes what the rock is chemically made of. There is always some sort of chemical reaction! 1. Changes the color 2. Changes the chemical composition 3. Releases gas (bubbles) 4. Releases odor

Chemical Weathering Hypothesis- make a prediction using no personal pronouns using an If, Then, Because statement. You will weather your chalk for 5 million years 1. What will happen to the chalk if it comes in contact with vinegar (weak acid)? If__________ then___________ because________________

Procedures 1. Make observations about the chalk in your data table 2. Cut the chalk into a third, give one piece to each student and scratch your name on to it 3. Place the chalk in the beaker, use the droppers to drop 20 drops of vinegar onto your chalk 4. Note any observations after every 5 drops 5. (A or 1 is the timer for your group) Initial Observations During How hard is the chalk? Experiment Can it be scratched by your finger nail? Observations after the experiment

Conclusion Chalk In this activity the vinegar, which is acidic, reacts with the chalk (which is made from calcite like shells of sea animals and limestone) forming carbon dioxide gas (the bubbles you see during the reaction are the carbon dioxide gas, CO 2), water, and another calcium compound. 1. Describe what happened to the chalk? 2. Think of the rock cycle, what process of the rock cycle did you demonstrate? 3. How do you think this might happen in the natural world? (chemical weathering examples) 4. Critically think, what role do humans play in making water (rain, oceans) more acidic?

Exit Ticket 1. What is chemical weathering? 2. What is an example of chemical weathering? 3. Mechanical weathering breaks rocks apart, exposing more surface area. How do you think mechanical weathering can affect the rate at which chemical weathering occurs on the rock. 4. Why would 10, 1 kg pieces of limestone weather more quickly than one 10 kg piece of limestone?

Do Now 1. Make observations about the picture to the right, then make an inference. What kind of weathering took placemechanical or chemical? • If it’s chemical, explain what type and why. • If it’s mechanical, explain what type and why.

Earth Changes Earth is constantly changing, and events occur that can change the face of the Earth. This can happen quickly or slowly Rapid Changes Slow Changes Earthquakes Weathering Tsunamis Erosion Volcanoes Deposition Rock slides

Deposition Notes Deposition occurs when there is a reduction in the energy of motion of the wind, running water or glaciers. The heavier materials are dropped (deposited) first followed by the lighter materials. Wind deposits materials when it loses energy of motion often due to either the wind and particles hitting an object or the wind slowing down. Water speed slows due to meanders or entering another water body so it loses energy of motion therefore dropping the sediments it is carrying. When the wind deposits materials it may make a dune or sand ripple. Water can make deltas or stream valleys V-Shape valleys Glaciers When a glacier slows due to a lack of energy of motion It deposits materials along the front and sides of the glacier as piles of till known as moraines. Carves a U-Shape Gravity Mass movement or mass wasting is movements of masses of bodies of soil, bed rock, rock debris, soil, or mud which usually occur along steep -sided hills and mountains because of the pull of gravity. Landslides, mud slides, and avalanches result

Deposition What is deposition? What are some examples of areas in which sediment gets deposited? Boards Up Match the following landforms with the terms below that are involved in creating them Wind, Gravity, Running Water, Glaciers

Homework Worksheet is due tomorrow

Do Now (Probably Wont Do This) Identify the following descriptions of weathering as either Chemical or Mechanical. 1. Tree roots cracking the concrete foundation of a house. 2. Limestone dissolved by carbonic acid. 3. The oxidation (rusting) of minerals in rocks that contain iron. 4. Repeated freezing and thawing of water in the cracks of rocks.

Erosion and Deposition Erosion and deposition change and shape the Earth around us. 1. Using your tins, and sediment, make sure your sediment is at the correct height 2. Place the indicator at the top of the hill. 3. Use the water – Record speed by timing how long it takes for the slider to move to the bottom, and measure the distance it traveled. 4. Use ice cube- Record speed of erosion by timing how long it takes for the ice cube to move to the bottom, and measure the distance it traveled. Record your observations into the data table.

Horizontal Vs. Vertical Deposition Sorting Horizontal Sorting When sediment is deposited in a lake or a stream The largest sediment is deposited where the water moves the fastest, and the smallest is where the water moves the slowest. Vertical Sorting When sediment is suddenly dropped in water the sediments separate by size Largest on bottom, smallest on top.

Slower River It starts out fast due to the steep slopes from the higher elevations then Deposition gradually slows down as the land becomes more flat. Here As a river moves from the source Where will larger sediment most likely be deposited? Where will the smaller sediment most likely be deposited? Larger Sediment Smaller Sediment Faster River Erosion Here

STREAM VALLEY ri Ver Shaped

Glacier Valley U -Shaped A U-shaped valley is formed by the movement of a glacier down a slope. It has a characteristic U shape, with steep, straight sides and a flat bottom. The U-shape is due to the erosion of the glacier because of it’s weight as it scrapes the bottom of the valley floor.
