  1. 7. Core innermost geologic layer of planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius
  2. 9. soil that dominates the deserts and xeric shrublands, which occupy about one third of the Earth's land surface.
  3. 10. Rock types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation.
  4. 11. a soil of an order rich in aluminum oxide and organic matter, typically characterized by low fertility, and including most podzols.
  5. 13. also called hard coal, the most highly metamorphosed form of coal. It contains more fixed carbon (86 percent or greater on a dry, ash-free basis) than any other form of coal
  6. 14. a soil type which has deep, high organic matter, nutrient-enriched surface soil (A horizon), typically between 60 and 80 cm in depth.
  7. 15. Cycle the pathway that chemical elements take in the surface and crust of the Earth. Encompasses the natural separation and concentration of elements and heat-assisted recombination processes.
  8. 16. a gray crystalline allotropic form of carbon which occurs as a mineral in some rocks and can be made from coke. It is used as a solid lubricant, in pencils, and as a moderator in nuclear reactors.

  1. 1. Coal a type of coal containing a tar-like substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams
  2. 2. Rock one of the three main rock types. Formed through the cooling and solidification of magma or lava.
  3. 3. a layer inside a planetary body bounded below by a core and above by a crust
  4. 4. Coal a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%; is considered the lowest rank of coal due to its relatively low heat content.
  5. 5. the outermost layer of Earth’s lithosphere that makes up the planet’s continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates.
  6. 6. also called hard coal, the most highly metamorphosed form of coal. It contains more fixed carbon (86 percent or greater on a dry, ash-free basis) than any other form of coal
  7. 8. Cycle the pathway that chemical elements take in the surface and crust of the Earth. Encompasses the natural separation and concentration of elements and heat-assisted recombination processes.
  8. 12. a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools.
  9. 13. a soil of an order comprising leached basic or slightly acid soils with a clay-enriched B horizon
