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 can also be formed when minerals are dissolved in  water and are then resolidified. This type of sedimentary rock is  called a chemical sedimentary rock. Oolitic limestone is a good  example of this type of sedimentary rock.1 person found this useful.gneous rocks are made from magma. Magma is made of melted rocks.  (When it is underground it is called magma, when it erupts on the  surface of the earth, it is called lava â¦ . It's the same material  though.) When magma/lava cools, it forms igneous rocks.
