  • Rock that forms when magma cools and hardensAnswer

  • Igneous Rock Home

  • Igneous rock that is rich in feldspars and silica and generally light in color Answer

  • Felsic Rock


  • What can change the angularity of sediment? Answer

  • How far the rock has been carried, the agent that carried it Home

  • The pattern that illustrates the order in which minerals crystallize from cooling magmaAnswer

  • Bowens reaction seriesHome

  • Igneous rock that is rich in Mg and Fe is generally dark in colorAnswer

  • Mafic Home

  • Sedimentary rock that is made up of rock fragments that become compacted or cemented together Answer

  • HomeClastic Rock

  • Layers and bed of sedimentary rock are examples of ________Answer

  • Stratification Home

  • The crystallization and removal of different minerals from cooling magmaAnswer

  • Fractional Crystallization Home

  • Lumps that have compositions different from the main body of rock


  • Concretions Home

  • Forms when minerals precipitate from a solution or settle from a suspension Answer

  • Home .

    Chemical sedimentary Rock

  • Rocks that forms when existing rock is altered by forces of heat, pressure or chemical processes Answer

  • Metamorphic Home

  • Changes in temperature and pressure over a large area Answer

  • Regional metamorphism Home

  • This texture results when extreme pressure causes minerals in Metamorphic rock to realign, or when minerals separate out into dark and light bands Answer

  • How do most sedimentary rocks form?Answer

  • Compaction and Cementation Home

  • AnswerRocks from magma that cools deep inside Earths crust

  • Intrusive igneous Home

  • Rock formed from the cooling and solidification of lava at Earths surface


  • Extrusive Igneous Rock Home

  • Formations that spread over 100 km squared Answer

  • Batholiths Home

  • Process in which minerals precipitate into pore spaces between sediment grains and bind sediments together Answer

  • HomeCementation

  • AnswerRocks change from one type to another as a result of geologic forces and processes that are part of the ______

  • The Rock Cycle Home

  • A type of rock with vesicular texture has what in it?Answer

  • Air bubbles from dissolved gases Home

  • Texture with a mixture of large and small crystals Answer

  • Porphyritic Home

  • Forms from the remains of plants and animals Answer

  • Organic Sedimentary Home

  • Granite has large, well-developed crystals giving it what kind of texture? Answer

  • Coarse-grained texture Home
