Folded mountains form

1. Folded mountains form • When isostasy occurs • When continents collide (like Asia and India, and the Himalayas) • When continents diverge • After earthquakes

2. When the oceanic and continental lithospheres collide • Oceanic plates subduct • Continental plates subduct • They stop each other • They reach isostasy

3. What happens when two oceanic plates collide? • The denser plate fractures • The less dense plate fractures • The less dense plate subducts • The denser plate subducts

4. What type of mountain is formed when higher blocks fault? • A folded mountain • A salt-block mountain • A fault-block mountain • A flawed-block mountain

5. What happens when two continental plates collide? • Large mountains can form • Dome mountain are likely to form • The plates subduct beneath each other • The impact can cause large earthquakes

6. What is subduction? • Once plate collides with another • One plate destroys another • One plate goes beneath another • One plate divides another

7. Which of these are all types of mountains • Rolling, glacial, subterranean, cascades • Rocky, green, smoky, white • Fault-block, dome, volcanic, folded • Salt-block, dome,magmun,frozen

8. What happens when oceanic and continental plates collide? • The asthenosphere and the lithosphere are disrupted • The continental lithosphere subducts beneath the oceanic lithosphere • Mountains can be created through uplift and volcanic eruptions. • Valleys are created by the excessive energy release

9. A dome mountain is a mountain formed • By the collision of continental plates • By the eruption of magma from below Earth’s surface and out the top. • When faults break off dome-shaped rocks • By pressure from magma below Earth’s surface that does NOT erupt

10. A volcanic mountain is formed by • The uplift of rock during continental plate collisions • Rock layers that are bent and squeezed • Pressure of magma that does NOT erupt on the Earth’s surface. • Magma eruptions on Earth’s surface

11. What are the fasted waves? • P waves • T waves • S waves • Q waves

12. Earthquakes generally occur at plate boundaries where • Stress on rocks is greatest • The most rocks found • Stress on rocks is low • Magnetic pull is greatest

13. To find the distance to an earthquake’s epicenter, scientists • Chart the lag time between preshocks and aftershocks • Use radio wave detection devices • Analyze the arrival times of P and S waves. • Analyze the arrival times of Love waves an Rayleigh waves.

14. If you are in a car during an earthquake, you should • Drive to a bridge • Stop in a safe place • Get out and run like the wind • Park east of tall buildings

15. What happens to tsunamis as the move toward shore? • They decrease in height • The die out • They turn to riptides • They increase in height

16. Which is NOT a cause of tsunamis? • Volcanic eruption • Tornado • Undersea landslide • Undersea earthquake

17. P waves are also known as • Secondary waves • Compression waves • Love waves • Rayleigh waves

18. How do scientist find the epicenter of an earthquake • By comparing arrival times of P and S waves • By digging as several locations • By comparing departure times of P and S waves • By looking at satellite photos of tsunamis

19. Why do earthquakes usually occur at plate boundaries • The rock at the edges of tectonic plates is soft, and gives easily • Rock at the edges of tectonic plates is under great stress. • The boundaries between tectonic plates have been seismically active for millions of years • The last place that motion in an earthquake is detected.

20. This area is both a major earthquake zone and volcano zone. • Pacific ring of volcanoes • Pacific ring of fire • Oceanic ring of fire • Pacific island arc

21. Lichens and moss produce weathering agents called • Exfoliation • Organic activities • Organic acids • Sulfuric acids

22. Which of the following is NOT an agent of mechanical weathering • Ice • Wind • Acid • Gravity

23. Abrasion is caused by all of the following EXCEPT • Wind • Water • Ice wedging • Gravity

24. How does the amount of a rock’s surface area affect weathering? • Larger area, more weathering • Larger area, less weathering • Smaller area, more weathering • No affect at all

25. Plant and animal activities cause what king of weathering • Chemical • Mechanical • Chemical and mechanical • None at all

26. Climates that have the fastest rate of weathering are • Hot and dry • Hot and wet • Cold and dry • Cold and then hot

27. Steep slopes have high amounts of what kind of weathering • Chemical • Mechanical • Chemical and mechanical • None

28. Tropical climates generally form soil in which the “B” horizon is covered in a thin layer of Sand Rock Humus Clay

29. In which of the following erosion processes is gravity NOT a major factor • Creep • Mudflow • Dust storm • Slump

30. Which of the following is an example of a peneplain? • Low, rolling hills • Sand dunes • Valleys • Ponds

31. In what kind of climate is the weathering rate the slowest • Cold, wet • Alternating hot and cold • Hot and dry • Warm and humid

32. When overlying rocks are removed from granite that was formed deep beneath Earth’s surface decreases, and the granite forms long curved cracks called • Exfoliation • Joints • Gullies • Valleys
