Metamorphic rock
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
Metamorphic Rocks are formed two ways: Regional Metamorphism Contact Metamorphism In regional, two plates collide and through pressure and friction to change igneous rock to metamorphic. In contact (more familiar to me) lava (hot liquid?) contacts any type of rock and doesn't not melt but sorta loosens it up so the crystals inside can rearrange.
Metamorphic rock is formed by heat and pressure making changes to igneous and sedimentary rock.
The difference between metaporphic and ignous rock are that ignous rock is formed by cooling of magma and metaporphic is formed by temperature and pressure changes inside the earth
Breezes, or wind, are the movement of air particles. They are formed by the constant changes in temperature/pressure of the air. Take into account that when a high pressure front meets a low pressure front a storm appears.

metamorphic rocks are formed from sandstone

Metamorphic rock is formed by intense heat and pressure. Pressure compresses and changes the composition and appearance of these types of rocks. For example, whether pressure is evenly applied or not determines if metamorphic rocks are foliated.
Sedimentary rocks are formed by the compaction from overlying sediments and by the cementation resulting from the replacement of fluids with minerals, in a process of rock formation known as lithification.

The crystals were formed by hydrothermal fluids emanating from the magma chambers below
Cavities have exposed dentine which is the underlying layer of tooth structure (underneath enamel). The dentine is formed in cylindrical tubes that extend to the pulp. Sensitivity arises from changes in osmotic pressure of the dentinal fluids due to cold and sugar. This causes a stimulation and results in nerves sending out signals. This is the most accepted theory although there are others.
(Jaleb) Well not exactally it is formed by pressure but not by fire.
