  1. Rock Notes Rocks – solid earth materials formed from a mixture of minerals and sometimes other materials. Three types of rocks • Igneous rocks – forms when magma or lava cools. *extrusive igneous rock – rock that forms from quickly cooled lava. (smaller crystals) *intrusive igneous rock – rock that forms from slowly cooled magma. (larger crystals)

  2. 2) Metamorphic rocks – rocks that have changed due to heat and pressure. *foliated–banded (mineral grains flattened and aligned) *nonfoliated – not banded Marble - nonfoliated Gneiss - foliated

  3. 3) Sedimentary rocks – formed from bits of rocks, minerals, remains of living things, and dissolved minerals from water. *clastic (detrital) – cementing of grains *chemical – forms when minerals come out of a solution and settle on the ocean floor. *organic – forms from the remains of once-living things Sandstone - clastic Rock salt - chemical Chalk - organic

  4. Rock Cycle – constant changing in the form and structure of rocks.
