  1. Jeopardy Final Jeopardy

  2. Vocab-100 • The removal of surface material through the process of weathering • What is erosion?

  3. Vocab-200 • The process of moving eroded materials from one place to another. • What is sediment transport?

  4. Vocab-300 • Dropping or leaving sediment behind • What is deposition?

  5. Vocab-400 • When erosion occurs as material moves down a slope, whether triggered by snow, heavy rains, earthquakes, or human activity. • What is mass wasting?

  6. Vocab-500 • Often used to piece together the geologic history of an area. • What is surface sediment?

  7. Water-100 • The land area that gathers water for a major river. • What is a drainage basin?

  8. Water-200 • As water flows downhill under the influence of gravity, water erodes the Earth’s surface, creating its own paths called ___________. • What are channels?

  9. Water-300 • After a river floods and as floodwaters subside and drop their sediment load, _________ form along the valley sides. • What are floodplains?

  10. Water-400 • A fan-shaped sediment deposit formed at the mouth of a river • What is a delta?

  11. Water-500 • These form on the inside bends in a river channel, where the water speed is slowest • What are sandbars?

  12. Glaciers and Wind-100 • A large mass of moving ice • What is a glacier?

  13. Glaciers and Wind-200 • Deep grooves in rock caused by glaciers • What are striations?

  14. Glaciers and Wind-300 • Material deposit by glaciers melting, composed of a collection of sediments ranging from small stones to large boulders. • What is till?

  15. Glaciers and Wind-400 • Removal of small particles by wind, leaving heavier particles behind. • What is deflation?

  16. Glaciers and Wind-500 • These form as wind moves sand-sized particles into distinct landforms. • What are dunes?

  17. Waves and Mass Wasting-100 • Movement of water parallel to the shoreline • What is longshore current?

  18. Waves and Mass Wasting-200 • Constant wave action can erode the base of coastal _______ causing their collapse into the sea. • What are cliffs?

  19. Waves and Mass Wasting-300 • Landforms that are parallel to the shoreline • What are sandbars?

  20. Waves and Mass Wasting-400 • Sandbars that extend into the water from land and curve back toward land in a hook shape. • What are spits?

  21. Waves and Mass Wasting-500 • Concave, upward scars from which material has detached and moved downhill. • What are slumps?

  22. Miscellaneous-100 • Ridges of till that accumulate at the edge and end of a glacier. • What is a moraine?

  23. Miscellaneous-200 • Glacial deposits in flat outwash plains often become this. • What is fertile soil that support plant growth?

  24. Miscellaneous-300 • _________ often takes place on steep slopes or on slopes that lack vegetation. • What is mass wasting?

  25. Miscellaneous-400 • Geologists can locate ancient landslides by their ______________ sediment structure. • What is disorganized?

  26. Miscellaneous-500 • Ice sheets that occupy large land areas in colder climates-especially in Greenland and Antarctica. • What are continental glaciers?

  27. Final Jeopardy • The age of a river can be determined from ________. • What is the shape of its channel?
