Erosion and Deposition

Sort the following actions as either erosion or deposition. Deposition Layers of sediment forming at the bottom of the ocean Landforms called deltas that form where rivers flow into other bodies of water Waves dropping sand on the beach Glaciers that drop rock, sand and other debris forming landforms known as moraines Sediment accumulating on the inside of a meander Erosion Large sediments rolling along the bottom of a stream The force of gravity pulling sediments down a slope or hill Ocean waves taking sediment away from the shoreline Wind blowing sand from one location to another Muddy water being carried away by a fast moving river What evidence might be found on the surface of bedrock that indicates a glacier had passed over the surface? rounded particles jagged edges parallel scratches What is the general relationship between stream velocity and diameter of particles transported by a stream? direct indirect cyclic Unsorted, angular, rough-surfaced cobbles and boulders are found at the base of a cliff. What most likely transported these cobbles and boulders? running water glaciers gravity What change will a pebble usually undergo when it is transported a great distance by streams? It will become jagged and its mass will decrease It will become rounded and its mass will decrease The pebble will not change when it is transported by a stream A mixture of sand, pebbles, clay and silt of uniform shape and density, is dropped from a boat into a calm lake. Which material most likely would reach the bottom of the lake first? sand pebbles silt What is the relationship between the shape of the particle and the settling rate? Cyclic Direct Indirect When a stream's velocity decreases from 50cm to 5 cm what sediment will be deposited? Pebble boulder clay How does the kinetic energy change, when a river enters an ocean and sediment is deposited? Increase Decreases Stays the Same River Features What feature is being formed in the video above? Stream Meanders - Inside or Outside of Curve The following diagram (from Google Earth) shows meanders in the wetlands located to the north of Captree, Long Island. Label each section as either outsideor insideof the curve. Write either of the bold words. inside inside outside inside inside outside outside Stream Meanders - Faster or Slower The following diagram (from Google Earth) shows meanders in the wetlands located to the north of Captree, Long Island. Label each section as either the faster or slowerside of the curve. Write either of the bold words. slower faster slower slower slower faster Stream Meanders - Deep or Shallow The following diagram (from Google Earth) shows meanders in the wetlands located to the north of Captree, Long Island. Label each section as either the deep or shallow side of the curve. Write either of the bold words. deep shallow deep shallow deep shallow Let's go on a kayak adventure! You and your friends are going kayaking on a stream that has a bunch of meanders on a sunny morning at low tide. Since you took Earth Science you know that if you paddle on the wrong side of the curve you're boat will get stuck. What information do you tell your friends to follow? Write the term bold that best Do you paddle on the Inside or Outside of the curve Is this because the water will be Deeper or Shallower? Does this mean the water is moving Faster or Slower The correct side of the meaner to paddle on is experiencing Erosion or Deposition? Outside Deeper Faster Erosion Glacier Features One the diagram, write what feature is shown. Drumlin, Kettle Lake, Moraine, Outwash Plain Drumlin Moraine Kettle Lake Outwash Plain What evidence shows that much of New York State was deposited by glaciers? unsorted sediments horizontally sorted sediments rounder sediments What will be the most probable arrangement of rock particles deposited directly by a glacier? sorted and layered unsorted and layered sorted and not layered unsorted and not layered Wind Below is an image of a sand dune. On the diagram draw an arrow indicating the direction of the wind forming this dune. Sort the features with the agent of erosion that goes along with each feature.
