- 2. is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock.
- 5. the transformation of existing rock types, in a process called metamorphism, which means "change in form".
- 7. is a chemical compound consisting of one part silicon and two parts oxygen.
- 9. is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula.
- 11. the change of minerals or geologic texture in pre-existing rocks, without the protolith melting into liquid magma.
- 13. is the process of letting suspended material settle by gravity.
- 15. is formed through the cooling and solidification of magma or lava.
- 16. is the name of a group of rock-forming minerals that are typically found in mafic and ultramafic igneous rocks such as basalt.
- 17. is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.
- 20. is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions.
- 21. is a physical process that results in the phase transition of a substance from a solid to a liquid.
- 23. makes up a whopping 84% of Earth's total volume.
- 25. the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous.
- 27. are solid substances that are present in nature and can be made of one element or more elements combined together.
- 30. is a dense, coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxene.
Down
- 1. is the breaking down or dissolving of rocks and minerals on Earth's surface.
- 3. is any member of a family of anions consisting of silicon and oxygen.
- 4. is the laying down of sediment carried by the wind, water, or ice.
- 6. describes the outermost shell of a terrestrial planet.
- 8. is the movement of material across the Earth's surface by water, wind, ice, or gravity.
- 10. is the very hot, very dense center of our planet.
- 12. represents approximately 56% of Earth's total volume, between the transition zone and the outer core.
- 14. worn away soil and rock particles by moving agents such as wind, water, or ice and gravity elsewhere.
- 18. is a polyatomic anion with the empirical formula SO²⁻ ₄.
- 19. group of sheet silicate minerals includes several closely related materials having nearly perfect basal cleavage.
- 22. includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure.
- 24. is a salt of carbonic acid, characterized by the presence of the carbonate ion.
- 26. is a group of inosilicate minerals, forming prism or needlelike crystals.
- 28. zone of Earth's mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere.
- 29. types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral.
