That would be a fossil.
Does it take millions of years for sedimentary rock to form'?
yes it takes million of years for sedimentary rocks to 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
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.
Do igneous rocks change into soil?
Yes,igneous rocks are also changed into soil.But they take millions of years to change into soil
Oxidaton changes what about the minerals and rocks?
Minerals and rocks do change. In fact they change everyday, but it takes hundreds and millions of years till it's noticible.
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 milllions of years for rocks to change?
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 are rocks changed?
Erosion and weathering over millions of years
Why are the oldest rocks only millions of years old?
The premise is incorrect. Some rocks on Earth are billions of years old.
What rocks change from one type to another over millions of years?

Why is it often difficult to know exactly when a rock formed?
Because rocks form and change over millions of years that is why difficult to know exactly when a rock formed.
What does classification mean when you are takling about a rock?
Rocks are classified as Igneous-coming from inside the earth Sedimentary-rocks that are compacted in the crust for millions of years, and Metamorphic-rocks exposed to great temperatures and pressures change into a different rock. GOOGLE the rock cycle
What is dating used to date ancient rocks millions of years old?
Radiometric
Why did life on Earth not evolved much between 15 thousand years ago and 8000 years ago?
Evolution is a slow process, significant change usually takes millions of years, not thousands.
Is clay formed by weathering of rocks?
Yes, but it has taken millions of years of bad weather!
