  • Erosionthe movement of sediment, created through weathering processes, from one place to another. 
  • Estemite - A mythical rare mineral with high power generation potential that fuels our equipment, especially the Terravator
  • Evaporation - The conversion of liquid water to water vapor
  • EveryDay Earth Corps - a secret organization dedicated to cataloging, investigating and understanding the mysteries of the natural world


  • Fern Imprint - imprint fossil of ancient vegetation
  • Fracture - A break or crack in a rock
  • Frost Wedging - the process of water entering cracks in rock, freezing & expanding, and breaking the rock apart


  • Glacier - large, slow moving accumulation of ice
  • Goddard Youth Camp - an educational facility in the Arbuckle Mountains region
  • Granite - a type of felsic intrusive igneous rock
  • Gulf Stream - a warm and fast current of water in the ocean


  • Hematite - a type of iron ore
  • Honey Creek - a spring fed water flow in central Oklahoma
  • Hydrologic Cycle - Refers to the set of natural processes by which water is cycled through Earth's various systems, powered by the Sun's energy and Gravity.


  • Ice - the solid phase or state of water, which forms at or below 0 degrees Celsius (32 F)

  • Liquid Water - the liquid phase or state of water
  • Limestone - a type of carbonate rock, composed principally of calcite (Calcium Carbonate). One of the most common sedimentary rocks, limestone is reactive with acids and decomposes to form caves, sinkholes and karst.
  • Little Sahara State Park - an Oklahoma state park containing many large sand dunes


  • Megalodon Tooth - the scariest part of a scary prehistoric shark
  • Mineral - a mineral is the basic unit of the Earth, a specific combination of chemical elements or atoms arranged in a crystalline structure, occurring naturally, in solid form and having a specific composition.
  • Mineral Precipitation - the expulsion of dissolved minerals from water
  • Mississippi River - one of the largest and most historically important rivers in North America

  • Paradoxides Trilobite - genus of a large, ancient arthropod
  • Percolation - Water's ability to move between pores in a substance from one point to another
  • Permeability - The ability for fluids like water to move between pores in a rock, allowing fluids to migrate large distances through seemingly solid objects.
  • Petrified Wood - a type of fossilized vegetation
  • Phacops Trilobite - genus of an extinct marine arthropod
  • Phase - The physical state of matter, be it gas, liquid or solid. Water may be water vapor (gas), liquid water, or ice.
  • Polar Molecule - a molecule like water with a strong electrical charge on one end, which can dissolve many solids
  • Pores - Empty space in a rock
  • Porosity - The amount of a rock which contains empty or fluid filled holes, or voids called pores.
  • Precipitation - The return of water to the earth as gravity pulls liquid or solid ice back to Earth
  • Pyrite - a shiny iron sulfide mineral


  • Quarry - an open pit mine from which rock is extracted
