Sedimentary rock metamorphosis can occur very rapidly ( in geologic terms) as is the case with skarn, a contact metamorphic rock, or quite slowly as is the case with slate, which has proceeded through metamorphism in stages from mud to mudstone to shale to slate, a process taking millions of years.
All rocks on Earth take part in the "Rock Cycle". For an igneous or metamorphic rock to change into a sedimentary rock, they must undergo weathering and erosion by wind, water, and/or ice. The broken down pieces of rock (sediments) settle into layers that form a sedimentary rock.
Igneous rock can become metamorphic rock through the pathways of regional metamorphism, where intense pressure and heat from tectonic forces transform the rock, or contact metamorphism, where it is altered by high temperatures from nearby magma intrusion.
Metamorphic rocks typically take the longest to form, as they are created from existing rocks that undergo extreme heat and pressure over long periods of time in the Earth's crust. This process can take millions of years to transform the original rock into a metamorphic rock.
Metamorphic Rock Metamorphism means to change form; this is exactly what metamorphic rocks do. This paper will take a look at the Earth's rock cycle to examine exactly where the metamorphic rock fits into it. It will also look at how metamorphic rocks are formed and the relationship between metamorphic rocks and igneous rock and sedimentary rocks. This paper will examine the geological characteristics and materials of metamorphic rocks, and examine some examples of metamorphic rocks and will describe mineral composition of some examples and explain its economic uses. The Rock Cycle The rock cycle helps people to understand the starting point of the igneous, sedimentary, and metamorphic rocks. In addition to explaining how each of the rocks are connected through the process. The rock cycle explains to us how the Earth assists in changing one type of rock into another type of rock. The process begins when magma, found from beneath the Earth's surface or from a volcano, cools and crystallizes. This process forms rocks called igneous rocks. When an igneous rock is exposed to weathering and erosion and compacted by the weight of the groundwater, which is otherwise known as lithification, it creates a sedimentary rock. When sedimentary rocks are buried deep within the Earth and evolve into mountains or are exposed to extreme pressure and intense heat it will then turn into the last cycle of rock, the metamorphic rock. Metamorphic rocks can even evolve from other metamorphic rocks. How Metamorphic Rocks Are Formed Within the Rock Cycle Metamorphic rocks are created when they are exposed to extreme heat, pressure, and chemicals. Rocks are usually exposed to extreme heat, pressure, and chemicals at the same time. Metamorphism occurs in one of two situations, contact metamorphism or regional metamorphism. Contact metamorphism occurs when a rocks experience a rise in temperature when it is exposed to magma. Heat is the most important source of metamorphism because... [continues]
Intrusive igneous rocks, such as granite, take the longest time to cool because they form beneath the Earth's surface where heat dissipates slowly. This slow cooling process allows large crystals to form in the rock.
Heat and pressure
Very high, sustained temperatures are required as the metamorphic rock must melt down and then re-solidify
No. Metamorphic rock froms from processes that take place in the solid state. Rocks that form from molten material are igneous.
No one really know what rock came first but I would assume it would be Igneous because it came from volcanoes and those have been around a long time. Sedimentary rocks take millions of years to form, and metamorphic take long as well. The best answer would definitely have to be igneous.

lava dries air smoothens it and water confines it
there are several ways such as heat & pressure, melting, chemical weathering, compression, compaction & cementation, but it depends on the kind of rock it is for what process it has to go through. -Cutegirl99

New rocks are formed, Igneous Rock, Sedimentary Rock, and Metamorphic Rock. It will take over a million years to complete the rock cycle, then it will start all over again.
Metamorphic rocks typically take the longest to form, as they are created from existing rocks that undergo extreme heat and pressure over long periods of time in the Earth's crust. This process can take millions of years to transform the original rock into a metamorphic rock.
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.
