HW #2 Landscape 2016 Section: Name: ate: 1. ase your answer(s) to the following question(s) on the map below, which represents two bridges that cross the Green River. Letters,, and represent locations in the river. ball was dropped from bridge 1 at location and the distance and travel time to location were recorded. The results are shown in the data table below. Travel from to istance (cm) Time(s) 12,000 240 On the map below, place an X at the location between the bridges where the greatest amount of deposition is most likely occurring. 4. Lichens are usually the first organisms that appear in barren, rocky areas. They use rootlike structures to split bedrock into small fragments. Lichens also secrete acidic solutions that help break down rock. The cross sections below represent an area when lichens first appeared (time 1) and that same area hundreds of years later, after it was changed by lichens and exposed to air and water (time 2). The soil shown in time 2 was formed mainly by. compaction and cementing. weathering and biological activity. faulting and tilting of rock strata. mass movement and deposition of particles 5. Which New York State landscape region is mostly composed of horizontal sedimentary bedrock at high elevations?. Hudson Highlands. llegheny Plateau. Taconic Mountains. tlantic oastal Plain 6. The largest sediment particles that can be transported by a stream traveling at a velocity of 200 centimeters per second are 2. etermine the rate at which the ball traveled, in centimeters per second, from location to location.. boulders. cobbles. pebbles. sand 3. fter a thunderstorm, the velocity of the river at location was 100 centimeters per second. What was the largest type of sediment transported by the river at this location? 7. On October 14, during the flood, the discharge of the San Juan River changed dramatically. The change in the river s discharge at this location was related to an increase in the river s. velocity. gradient. channel length. sediment deposits page 1
8. ase your answer(s) to the following question(s) on the diagram below and on your knowledge of Earth science. The diagram represents a portion of a stream and its surrounding bedrock. The arrows represent the movement of water molecules by the processes of the water cycle. The water table is indicated by a dashed line. Letter represents a water cycle process occurring at a specific location. Letter d represents the distance between the water table and the land surface. 12. The diagram below represents three identical beakers filled to the same level with spherical beads. eads of 0.15-cm diameter eads of 0.45-cm diameter eads of 0.70-cm diameter If the packing of the beads within each beaker is the same, which graph best represents the porosity within each beaker? eaker. Explain why the distance, d, from the water table to the land surface would decrease after several days of heavy rainfall.. 9. Slightly acidic groundwater has been seeping through cracks and openings in the limestone bedrock of this area, producing caves. State whether the type of weathering that produces these caves is mainly chemical or physical, and identify one characteristic of limestone that allows this type of weathering to occur.. 10. Which soil conditions normally result in the greatest amount of runoff?.. low permeability and gentle slope. low permeability and steep slope. high permeability and gentle slope. high permeability and steep slope 11. Which change is most likely to occur in a landscape if its climate changes from humid to arid?. Wind will become a more important agent of erosion.. Surface features will become more rounded.. hemical weathering will increase. 13. Which soil characteristic allows greater amounts of water retention?. large-size particles. small-size particles. high-density particles. low-density particles. Vegetation will increase.

14. Trees growing on the edge of a river s meander are most likely to fall into the river due to. deposition on the inside of the meander. deposition on the outside of the meander. erosion on the inside of the meander. erosion on the outside of the meander 18. Which two types of rock are most commonly found as outcrops in New York State s Newark Lowlands landscape region?. rock salt and gypsum. limestone and granite. gneiss and quartzite. conglomerate and sandstone 15. ase your answer(s) to the following question(s) on the block diagram and information below. The diagram is of Niagara Falls region as viewed from the north. 19. Which two cities are located in the Interior Lowlands?. Elmira and inghamton. Riverhead and New York ity. Massena and Old Forge. uffalo and Watertown The Niagara River began to flow over the Niagara Escarpment about 12,000 years ago when the last Pleistocene ice sheet melted and retreated north from the Niagara Escarpment. Since that time, Niagara Falls has eroded upriver, leaving a deep, steep- sided valley that is 11,000 meters long. The top bedrock layer of the escarpment is the Lockport dolostone which lies above the Rochester shale. The shale is more easily weathered than the dolostone. This causes the dolostone to be undercut. s a result, the dolostone breaks off in large blocks that tumble to the base of Niagara Falls. In which New York State landscape region is Niagara Falls located? 20. Old Forge and Watertown, located at nearly the same latitude in New York State, have very different landscapes. Which factor is primarily responsible for these landscape differences?. average annual temperature. average annual precipitation. bedrock structure. soil characteristics 16. Toward which compass direction is the location of Niagara Falls likely to move in the future? 21. The map below shows four watershed regions in New York State labeled through. Toward the 17. Sediment samples through below have the same volume and packing, but contain different percentages of various particle sizes. Sample : 75% clay and 25% silt Sample : 25% clay and 75% sand Sample : 50% pebbles and 50% sand Sample : 50% pebbles and 50% cobbles Which sample most likely has the greatest permeability?.... Which lettered section represents the watershed of the Mohawk and Hudson Rivers?.... Section: page 3 HW #2 Landscape 2016
22. The block diagram below represents the drainage basins of some river systems separated by highland divides, shown with dashed lines. The arrows show the directions of surface-water flow. 24. The block diagram below represents a portion of the Grand anyon. This region is best classified as a The three areas separated by highland divides are called. plateau. mountain. plain. lowland. meanders. floodplains. watersheds. tributaries 23. ase your answer(s) to the following question(s) on the diagram below, which shows a model used to investigate the erosional-depositional system of a stream. The model was tilted to create a gentle slope, and a hose supplied water to form the meandering stream shown. 25. The photograph below shows farm buildings partially buried in silt. Which diagram best represents where erosion, E, and deposition,, are most likely occurring along the curves of the meandering stream?. Which erosional agent most likely piled the silt against these buildings?. glacial ice. ocean waves. wind. mass movement.. 26. landslide is an example of. river deposition. glacial scouring. mass movement. chemical weathering.
