Across

1. massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere
4. Where living being/things can live
6. a series of waves in a water body caused by the displacement of a large volume of water
8. is any preserved remains, impression, or trace of any once-living thing from a past geological age
9. occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge
11. type of elastic wave, and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves
15. any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces
16. complex portion of the tectonic boundary between the Eurasian Plate and the Philippine Sea Plate
18. a linear feature that exists between two tectonic plates that are moving away from each other
21. composed of iron and nickel which lies above the Earth's solid inner core and below its mantle
23. a long, narrow ditch
25. movement of the Earth's continents relative to each other, thus appearing to "drift" across the ocean bed
26. is the name for all material of glacial origin found anywhere on land or at sea, including sediment and large rocks
28. the upper layer of the earth's mantle, below the lithosphere
29. Which crust are made of
31. locations where two plates slide past one another
34. series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake
37. Heat energy can transfer by convection when there is a significant difference in temperature between two parts of a fluid
39. the rigid outer part of the earth, consisting of the crust and upper mantle
41. a record recorder from seismograph
42. fossil fuel that forms when dead plant matter is converted into peat
43. Which the core is made of
45. underwater mountain system formed by plate tectonics
47. the point on the earth's surface vertically above the focus of an earthquake
48. the boundary surface between the earth's crust and the mantle
49. the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite
50. one of the scientists who created continental drift theory
