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.
Marble is another example of a metamorphic rock. It is formed from limestone. Metamorphic rocks sometimes contain fossils if they were formed from a sedimentary rock, but the fossils are usually squashed out of shape. Metamorphic rocks can be formed from any other type of rock-sedimentary or igneous.Remember these two examples of common metamorhpic rocks and where they come from:slate is formed from shale. marble is formed from limestone. 1  Page. 2  1. 3  2. 4  3. 5  4. 6  5.etamorphic rocks can be formed from any other type of rock-sedimentary or igneous.
