2. Large fractures(a break)in the earth's crust.
8. Gas part of the earth (oxygen & nitrogen etc).
9. the force that could create deformation on rocks in their shape and/ volume.
10. the uppermost layer of earth.
11. are fold structures formed when the originally rock layers have been folded upward
12. are folds structures when the original rock layers have been folded downward
13. solid part of the earth(rocks & minerals etc).
17. Large ocean waves caused by an earthquake under the ocean.
18. is a mixture of molten and semi-molten rock found beneath the surface of the earth.
19. occur when the horizontal layers are bent upward so that two limbs of the fold are still horizontal.
22. The process in which some of the minerals get dissolved in water.
23. ability of a rock material to handle stress depends on the elasticity of the rock.
24. fractures in rocks that show little or no movement at all.
25. The process in which atmospheric oxygen reacts with the rock to produce oxides.
27. This results because of the intense heating of the rock’s outer layers.
28. instrument that measures earthquake waves.
29. The process by which water is absorbed by the minerals of the rocks.
30. refers to the downslope movement of rock and soil under the influence of gravity.

1. Collapsed volcanoes
2. point under the earth’s surface where an earthquake starts
3. The outlet where magma escapes to the surface of the earth.
4. is a measure of the shaking created b the earthquake, and this value does vary with location
5. Plates moving apart
6. A volcano that is no longer erupting but is likely to erupt again in the future.
7. Bowl-shaped formation at the top of a volcano.
10. Plates come together
14. volcanic cone made up of layers of hardened lava.
15. Magma that reaches the earth's surface.
16. Tectonic plate moves over a magma ”plume”
20. place on earth’s surface directly above the focus
21. Also called composite volcanoes
26. The process by which various types of carbonates are formed.
