Reshaping the Earth

How was the Grand Canyon formed? Watch the video below and answer the questions that go along with it. Which river was responsible for the formation of the Grand Canyon? Mississippi River Colorado River Amazon River Nile River While the river was responsible for the depth of the grand canyon, what made it wider? Wind Erosion Mining Gravity Human interactions What type of plate boundary caused the whole Colorado Plateau to be pushed up? divergent convergent transform Sort the following examples into the three categories; weathering, erosion, or deposition. Weathering The process of breaking down rock on Earth's surface Acid rain breaking down limestone. Powerful waves of water wearing down rocks A glacier wearing down layers of rock. Frost wedging splitting rocks apart. Tiny particles of sand wearing away rock by wind abrasion. Roots of plants breaking rocks apart. Erosion A landslide rushing down a hill. Wind and water from a hurricane moving sediment. Waves removing sand from beaches. The process by which water, wind, ice, wind, or gravity moves pieces of rock or soil. Sand being moved by wind. A muddy river carrying sediment downstream. Rain washing away soil. Deposition A glacier dropping rock and other debris to form a moraine. Sediment settling at the bottom of the ocean. Waves building up sand on the beach. An alluvial fan forming at the base of a mountain stream. The process by which sediment settles and is deposited in a new location. A sand dune forming in the desert. A river delta forming. What is abrasion? When rocks carried by wind scrape other rocks A type of mechanical weathering All of the above When rocks stuck to the bottom of glaciers scrape bedrock Which of the following is an example of mechanical weathering? Water expands when it freezes in cracks in rocks Acid rain Oxidation Pressure created by runoff breaks down rocks Which of the following is an example of chemical weathering? Oxidation freezing and thawing actions of animal plant growth
