4. A portion of Earth made up of the crust and the solid portion of the upper mantle.
6. The process by which pressure of overlying sediments or pressure from the Earth compresses the particles of sediments.
8. Magma that emerges on the Earth's surface.
9. A scientist who studies the history of life on Earth through the fossil record.
10. The position on the surface of the Earth directly above the focus of an earthquake.
11. the process by which the spaces between particles of loose sediments are filled with a cementing agent.
15. Denoting or relating to rock that has undergone transformation by heat, pressure, or other natural agencies

5. Worn by long exposure to the atmosphere
7. The boundary between two rock sections that have been displaced relative to each other.
12. Underground layer of rock or sand that yields groundwater. bedrock. solid unweathered stone beneath surface deposits of soil. bulge. swell or protrude .
13. The remains of prehistoric animals and plants preserved in rock.
14. The hot liquid substance below the lithosphere that the plates float on.
15. Molten rock that triggers earthquakes and creates volcanoes as it rises within the Earth.
17. A slowly moving mass of ice. bayou. a swampy arm or slow-moving outlet of a lake. archipelago. a group of many islands in a large body of water.
