Not in all cases. sometimes it take shorter time. for example the contact metamorphic rock can be formed within a short period. If an area of sedimentary rocks experience a sudden volcanic eruption those sedimentary rocks will quickly metamorphose to Metamorphic rock. The reason it takes rock to change is because the process is a long one. Weathering, erosion, deposition, cementation/compaction. By the time the whole process go through it has been millions of years or thousands

How do high temperatures and pressures cause fossils to change into minerals or rocks to change their nature?
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 forces affect rocks above the earth's surface?
The main force that affects the rocks on the earth's surface is heat and erosion. Erosion causes rocks to have landslides and heat changes their structure causing them to take place as different structures.
What processes take place when igneous rocks are changed to sedimentary?
compacting and cementing
Would the oldest rocks on earth be igneous or sedimentary?
The creation of igneous rock from magma is dependent on the cooling rate of the magma. Some igneous rocks form almost instantaneously, and others take hundreds of thousands of years. So igneous rock could be the youngest of the three rock types at any given point in time.
How long does it take to form a metamorphic rock?
Metamorphism can be instantaneous as in the shearing of rocks at plate boundaries or can take millions of years as in the slow cooling of magma buried deep under the surface of the Earth. But on other hand metamorphism can be made in labs in one minute but certain chemical
Do igneous rocks change into soil?
Yes,igneous rocks are also changed into soil.But they take millions of years to change into soil
I am the process by which rocks change over millions of years?
Rocks change through the processes that take place within the rock cycle.
Can rocks only change on the inside?
No rocks can change on the outside also. But it is going to take a log time for a rock to change.
How long does it take for rocks to change?
about a year I guess
How much time does it take for rocks to change from one type to another type in the rock cycle?
The process is always ongoing, but a complete transformation from one type to another could take millions of years or more.
Why does it take thousands or millions of years to create sedimentary rocks when it may only take minutes to form igneous-?
It takes a long time for sedimentary rocks because the rocks have to break down in small pieces. The rocks are from the surfaces or the crust.
Did the sandstone of red rocks amphitheater take 12 million years to form?
no
How long does it take rocks to form?
Some extrusive rocks such as lava and ejecta form in minutes. Stalactites may form in a few tens of years, but commonly longer. Other rocks may take millions of years, and may have to be recycled through metamorphism to attain their final form.
How long could the rock cycle take for rocks to change?
Although some say it takes millions, maybe billions of years, it doesn't actually take that long. From my research, I have come to the conclusion that it only takes thousands of years not millions or billions
Does it take millions of years for sedimentary rock to form'?
yes it takes million of years for sedimentary rocks to form
How long does it take for a species to change?
it may take millions of years.
Which type of rock takes millions of years to form?
Sedimentary rocks. Igneous and metamorphic rocks take hundreds mostly. However, this does apply to all sedimentary rocks, due to the lengthly processes they go through.
