1.The world’s earthquakes are randomly distributed over the Earth’s surface.
TRUE
FALSE
2. Earthquakes tend to be not concentrated in narrow zones.
TRUE
FALSE
3. Some earthquakes are located near the edges of the continents, some are in mid continents, while others are in oceans.
TRUE
FALSE
4. Not ALL edges of continents, mid-continents, or oceans can be places where earthquake might occur.
TRUE
FALSE
5. Large part of the Pacific Ocean, northernmost Asia, majority of Europe, eastern portion of North and South America and western Africa can be places where earthquakes might occur.
TRUE
FALSE
6. Earthquake epicenters and volcanoes are both situated at the same locations.
TRUE
FALSE
7. Mountain ranges are found in places where volcanoes and/or earthquake epicenters are also located.
TRUE
FALSE
8. Geologic activities such as seismicity (occurrence of earthquake), volcanism and mountain formation are the basis of scientists in dividing Earth’s lithosphere.
TRUE
FALSE
9. Seismic waves are large pieces of the upper few hundred kilometers of Earth that move as a single unit as it floats above the mantle.
TRUE
FALSE
10. The plates move inconstantly in motion.
TRUE
FALSE
11. (a) are the edges where two plates meet.
12. A fault is formed in the Earth's crust as a brittle response to (a) .
13. The sense of stress determines the type of fault that forms, and we usually categorize that sense of stress in three different ways: 1.Tension , 2. compression, and 3. shear.
Rocks that are pulled apart are under (a) .
14. Tension is the major type of stress at (a) where two plates are moving away from each other.
15. (a) squeezes rocks together, causing rocks to fold or fracture.
16. It happens at (a) where two plates move toward each other.
17. When forces are parallel but moving in opposite directions, the stress is called (a) .
18. It is experienced at (a) where two plates are sliding past each other.
19. When a spreading center develops within a continent, the crust may break into several segments. The breaking leads to the formation of down faulted valleys called (a) .
20. Most divergent plate boundaries are situated along underwater mountain ranges called (a)
21.The convergence of plates causes the earth’s crust to spread or split apart.
TRUE
FALSE
22.The direction of the movement of each plate in divergent plate boundary is oppositely away from each other.
TRUE
FALSE
23.The rift valley decreases its length and depth as the spreading continues.
TRUE
FALSE
24. Divergent Plate Boundary is the type of boundary in which two plates move toward each other.
TRUE
FALSE
25. In Convergence of Continental plate and Oceanic Plate formation of trench, volcanic arc and even earthquakes happens.
TRUE
FALSE
26. In Convergence of Two Continental Plates mountains formed.
TRUE
FALSE
27. Transform Fault is a type of fault in which two tectonic plates slide past one another.
TRUE
FALSE
28. In Convergence of Two Continental Plates a collision zone is formed instead of subduction.
TRUE
FALSE
29. Most transform fault joins two segments of a mid-ocean ridge.
TRUE
FALSE
30. The presence of a ridge is an indication of diverging plates, and as the plates diverge between the two segments of the mid – ocean ridge, the adjacent slabs of crust are grinding past each other.
TRUE
FALSE
