Earthquakes

1. 1The earth is made up of three layers: the [blank_start]crust[blank_end], the [blank_start]mantle[blank_end] and the [blank_start]core[blank_end].

   1. Acrust
   2. Bmantle
   3. Ccore
2. 2Plates are [blank_start]pieces of rock mass[blank_end] into which the earth's surface is divided up.

   1. Apieces of rock mass
3. 3Plates are made up of the earth's [blank_start]crust[blank_end] and the [blank_start]upper part of the mantle[blank_end].

   1. Acrust
   2. Bupper part of the mantle
4. 4Plate boundary is the [blank_start]zone between two plates[blank_end].

   1. Azone between two plates
5. 5The movement of plates is caused by the [blank_start]convection of magma[blank_end] in the mantle.

   1. Aconvection of magma
6. 6There are three types of plate boundary: [blank_start]divergent[blank_end] plate boundary, [blank_start]convergent[blank_end] plate boundary and [blank_start]transform[blank_end] plate boundary.

   1. Adivergent
   2. Bconvergent
   3. Ctransform
7. 7When plates diverge, [blank_start]new crustal material[blank_end] is formed.

   1. Anew crustal material
8. 8When plates converge, the [blank_start]denser[blank_end] plate sinks into the mantle and melts.

   1. Adenser
9. 9In transform plate boundaries, plates [blank_start]slide past each other horizontally[blank_end].

   1. Aslide past each other horizontally
10. 10Earthquake is the [blank_start]sudden shaking[blank_end] of land.

    1. Asudden shaking

11. 11Earthquakes are most commonly found at [blank_start]convergent[blank_end] plate boundaries.

    1. Aconvergent
12. 12Iceland is located along [blank_start]divergent[blank_end] plate boundary.

    1. Adivergent
    2. Bconvergent
    3. Ctransform
13. 13Sichuan is located along [blank_start]convergent[blank_end] plate boundary.

    1. Aconvergent
    2. Bdivergent
    3. Ctransform
14. 14Japan is located along [blank_start]convergent[blank_end] plate boundary.

    1. Aconvergent
    2. Bdivergent
    3. Ctransform
15. 15California is located along [blank_start]transform[blank_end] plate boundary.

    1. Atransform
    2. Bdivergent
    3. Cconvergent
16. 16Earthquake is caused by the [blank_start]sudden release of energy[blank_end] stored in the rocks beneath the earth's surface.

    1. Asudden release of energy
17. 17When plates diverge, converge, or slide horizontally past each other, [blank_start]stress[blank_end] is applied to rocks, [blank_start]energy[blank_end] builds up in the rock layer and a [blank_start]fracture[blank_end] is formed.

    1. Astress
    2. Benergy
    3. Cfracture
18. 18When the [blank_start]pressure[blank_end] exceeds the [blank_start]strength[blank_end] of the rock, the rock breaks and moves.

    1. Apressure
    2. Bstrength
19. 19The energy released from the breaking of rock travel through as [blank_start]seismic waves[blank_end] which move out in all directions and [blank_start]shake[blank_end] the ground.

    1. Aseismic waves
    2. Bshake
20. 20The point where energy is released and earthquake waves are generated is called the [blank_start]focus[blank_end].

    1. Afocus
21. 21The point on the crustal surface directly above the focus is the [blank_start]epicenter[blank_end].

    1. Aepicenter
22. 22We can measure the strength of the shaking on the [blank_start]Richter Scale[blank_end].

    1. ARichter Scale
23. 23Earthquakes could cause bridges, roads and railways to [blank_start]collapse[blank_end].

    1. Acollapse
24. 24In earthquakes, people are [blank_start]injured[blank_end] and [blank_start]killed[blank_end] by collapsing buildings.

    1. Ainjured
    2. Bkilled
25. 25In earthquakes, breaking of power lines, gas and water pipes results in the [blank_start]cutting off[blank_end] of power and water.

    1. Acutting off
26. 26Earthquakes may trigger [blank_start]landslides[blank_end] and block the road.

    1. Alandslides
27. 27In earthquakes, collapsing of dams due to shaking may cause [blank_start]flooding[blank_end].

    1. Aflooding
28. 28Huge earthquakes under the sea may lead to great waves called [blank_start]tsunamis[blank_end].

    1. Atsunamis
29. 29Breaking of gas pipes and power lines may lead to [blank_start]fires.[blank_end]

    1. Afires.
30. 30Breaking of gas pipes and power lines may lead to [blank_start]fires.[blank_end]

    1. Afires.
