What is your age? Under 18 Years Old 18 to 24 Years Old 25 to 30 Years Old 31 to 40 Years Old 41 to 50 Years Old 51 to 60 Years Old Over 60 Years Old What is your gender? Male Female 1. What are the forms of erosion? Water Ice Chemicals Wind Organisms All of the above. 2. What does erosion affect? Rocks Topsoil. Riverbanks. Minerals. All of the above except for the first one. Answers 1, 2, 3, and 4. 3. Where in Canada, that was mentioned in the site, was formed by wind erosion? The Hoodoos in Alberta. The Valley of Wind in BC. The Grand Canyon in Arizona. Wind Farm in Nova Scotia. 4. How do rocks get eroded from wind erosion? Through biological weathering. Through mechanical weathering. Through chemical weathering. All of the above. 5. Why do rivers get wavier as they grow older? The water level increases. Because the inside of the curves of the river gets eroded by fast, running currents and the sediment from that flows to the outside of the curves. Because the outside of the curves of the river gets eroded by fast, running currents and the sediment from that flows to the inside of the curves. The water level decreases. Other forms of erosion affects the river. 6. What are the two categories of ice erosion? Nature's Bulldozer and Nature's Hammer. Earth's Screwdriver and Earth's Chisel. Earth's Hammer and Earth's Screwdriver. Nature's Fork and Earth's Spoon. Earth's Toolbox and Nature's Glaciers. Nature's Bulldozer and Nature's Chisel. 7. What is an example of a plant/organism that was mentioned in the site that produces an acid that wears away rocks? Lichen. Daffodils. Lotus. Trees. Mushrooms. 8. What is biological weathering? Weathering due to the pounding of soil and sand particles carried by wind. Weathering due to the movement of glaciers. Weathering due to acids and other chemicals. Weathering due to the pounding of soil and sand particles carried by water. Weathering due to the action of living things. 9. When does chemical weathering occur? When rocks and soil dissolve into nothing. When chemicals wear away objects. When plants and animals crack rock. When water, air, and other materials react with the minerals of a rock and change the substances that the rock is made of. All of the above. 10. How do you prevent erosion? Contour Plow (horizontal), for farming. Plant vegetation. The roots cling onto the soil, so it won't wash away as easily. Cover or mix the soil with mulch, straw or humus. Build windbreaks, such as trees or fences. All of the above. 11. Using the observations you made, why did the chalk fizz and bubble when it was mixed with vinegar? Chalk is a carbonate, and must be made out of limestone to fizz. The chalk is not real chalk. The reaction is suppose to be chemical weathering, and so it did so. There are air bubbles in the chalk and because the chalk was crushed, the air came out.
