How do high temperatures and pressures cause fossils to change into minerals or rocks to change their nature?
SaifAfridi
The changes take place because of recrystallization or realignment of existing minerals, or creation of minerals from existing assemblages that that can only be formed under certain specific ranges of temperature or pressure.

What are the two changes of a rock of metamorphism?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
Why does the color of granite never change?
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
What is the difference between disintegration and decomposition of rock?
Disintegration is fragmentation of rock and there is no chemical change during or after this process. Decomposition is resulting in the destruction of some or all of the unstable minerals and thus chemical change occur and new minerals are formed.
What is it called when chemical reactions dissolve the minerals in rock or change them into different minerals?
It's called dissolution, a form of chemical weathering.
What is the problem with using only color to identify a mineral Give an example of a mineral that demonstrates your answer?
The color of many minerals is highly variable. Many minerals are found in many different colors. Eg. while malachite is always green, and sulfur always yellow, quartz can come in shades of purple, green, blue, red, yellow, brown, pink, etc., and tourmaline, garnet, calcite, and fluorite are equally color variable.
What are normal R22 operating pressures?
The pressures depend on the temperatures so it is not possible to give "normal" temperatures. The pressures change with the outdoor and indoor temperatures. You need to be EPA certified to attach gauges to the unit to check the pressures.
Is a liquid at normal temperatures and pressures a physical or chemical change?
This liquid is only a liquid, not a change.
How does granite rock change to gniess?
When emplaced granite is subjected to pressures and temperatures from mountain building processes due to tectonic plate movements, the component minerals are essentially realigned perpendicularly to the direction of the stress.
Which can change from one state of matter to another at the temperatures and pressures experienced at Earth and surface?
water
How can mudstone be changed into a metamorphic rock?
It can be buried, and huge pressures and temperatures can change them into metamorphic rocks.
Which gas can change from one state of matter to another at the temperatures and pressures experienced at earth's surface?
Several of them.
What does heat do to a rock?
At high temperatures, the minerals in a rock can change to other minerals. And, of course, rock can melt.
Why cant color be used to identify minerals?
Color can change in a mineral when in certain temperatures
Why do fossils change?
fossils change i think
Do many metamorphic rocks have fossils in them?
it shows fossils because when sedimentary rocks are formed waste and decayed matter get cement( crushed ) togather. The change of mineral forms metamorphic rocks, but the fossils will remain in the rocks only the minerals will change. eg Limestone ----- marble. Limestone forms marble which is used to build taj mahal.
Changing form a liquid to gas is the answer is sublimation?
The answer is Sublimation of an element or compound is the change from a solid directly to a gas with no intermediate liquid stage. Sublimation is a phase transition that occurs at temperatures and pressures below the triple point.
What can fossils tell us about the future?
Fossils can tell us the climate and change in the future....
