They are formed when you have a rock that has pressure and heat added to it which creates a different rock. (ex. granite ___ geniss )
Fossils are formed from the buried remains of marine organisms. These organisms are under a tremendous amount of pressure and, over time, they fossilize.
Slate forms from shale under pressure.
Metamorphic rock can be formed a a combination of heat, pressure, and mechanical activity, or by heat, or by pressure from a mechanical activity such as plate motions.

No; the Solar System could only form because gravity was stronger in this case. Whether gravity is stronger, or the gas pressure, will depend on a variety of circumstances, but mainly, a sufficiently large amount of gas needs to get together. Some sort of initial impulse, such as a nearby supernova explosion, can help - but the very first stars must have formed without such events.
Marble is formed from limestone being buried, heated and subjected to pressure, causing minerals to recrystallise into different atomic structures, forming different minerals to the original limestone. In laymans terms this is the process that occurs to form all metamorphic rocks. The type of metamorphic rock formed is dependant on the chemical and mineral composition of the source rock, and the amount of heat and pressure the source rock is subjected to.
There is pressure within the earth due to the overlying material that the earth is formed from. The deeper within the earth you go, the greater the amount of overlying material pushing down due to gravity and so the greater the pressure. As the inner core has the largest amount of overlying material pushing down upon it, it experiences the greatest pressure.
(Jaleb) Well not exactally it is formed by pressure but not by fire.
formed by immense heat and pressure
they are formed by heat and pressure
Fossils are formed from the buried remains of marine organisms. These organisms are under a tremendous amount of pressure and, over time, they fossilize.
Marble is a metamorphic rock so it was formed by heat and pressure. :)
