Across
- 3. / metamorphic rock, such as slate and gneiss, whose mineral grains flatten and line up in parallel layers
- 7. / thick, gooey, molten rock material flowing from volcanoes onto Earth’s surface
- 9. / Physical property of some minerals that causes them to break along smooth, flat surfaces.
- 10. / naturally occurring, inorganic, solid, has a definite chemical composition, and crystal structure; the basic building block of all rocks
- 11. / process in which surface materials are worn away and transported from one place to another by agents such as gravity, water, wind, and glaciers.
- 12. / intrusive or extrusive rock formed when hot magma cools and hardens
- 14. / a type of igneous rock that generally contains large crystals and forms when magma cools slowly beneath Earth’s surface
- 15. / physical property of some minerals that causes them to break with uneven, rough, or jagged surfaces
- 17. / forms when sediments are compacted and cemented together or when minerals come out of solution or are left behind b evaporation
- 18. / metamorphic rock, such as quartzite and marble, whose mineral grains grow and rearrange but do not form layers.
- 21. / alteration of the composition of a rock
- 22. / forms when heat and pressure act on igneous, sedimentary, or other metamorphic rock and affect its form or composition, or both
- 24. Structure / Unique arrangement of atoms or molecules; repeating pattern
- 25. / Process that forms sedimentary rocks when layers of small sediments are compressed by the weight of the layers above them.
- 27. / the nature of something's ingredients; the way in which a whole or mixture is made up
Down
- 1. / measure of how easily a mineral can be scratched; is determined by the arrangement of the mineral’s atoms.
- 2. / the point or place where something begins.
- 4. / fine- grained igneous rock that forms when magma cools quickly at or near the Earth’s surface
- 5. / dropping of sediments that occur when an agent of erosion loses its energy and can no longer carry its load.
- 6. / loose materials, such as rock fragments, mineral grains, and the remains of once-living plants and animals, that have been moved by wind, water, ice, or gravity
- 7. / describes the way a mineral reflects light from its surface; can be either metallic or nonmetallic
- 8. / mechanical or chemical surface processes that break rocks into smaller and smaller pieces
- 13. / Sedimentary rock-forming process in which large sediments are held together by natural cements that are produced when water soaks through rock and soil.
- 16. / process in which sediments compact under pressure and cement together to form sedimentary rock
- 17. / color of a mineral when it is in powder form
- 19. / not consisting of or deriving (coming) from living matter
- 20. Cycle / model that describes how rocks slowly change from one form to another through time
- 21. / hot, melted rock material beneath Earth’s surface
- 23. / mineral that contains silicon and oxygen and usually one or more other elements
- 26. / removal of valuable minerals or other geological materials from the earth
