1 Removing heat energy, or cooling, decreases the motion of molecules. 2  If heat is added to a solid, the molecules can move fast enough to change from a solid to a liquid. ( 3 Melting). 4  If heat is added to a liquid, the molecules can move fast enough to change from a liquid to a gas.
Fossils usually only form in sedimentary rock. Sediments have to accumulate over the organism in order to preserve it. This could be a rapid burial, such as a volcanic eruption or mudslide, it could be sap from a tree oozing over an insect, or simply a slow sediment accumulation on the bottom of a lake.
  Sedimentary rocks are formed by the lithification of the sediments  which accumulate from the erosion of â¦ preexisting rocks of all  types. They also included rocks form from animal and plant remains.   Metamorphic rocks are formed when sedimentary or igneous rocks are  heated and or squashed.1  How Limestone Changes to Marble Marble is a type of metamorphic rock highly prized by builders for its outward beauty. 2  Relatively rare, it forms from limestone, a common type of sedimentary rock. 3  How limestâ¦.
