Some Igneous rocks cool off faster than others. The ones that cool off quicker takes a couple of months to cool. the ones that is slower to cool off takes several years. The faster ones cools glassy and with small grains. The slower ones cools off dull and with big grains.

∙ 11y agoThis depends on a lot of factors. Is it intrusive or extrusive? How large is it? How hot was it to start? What are it's chemical properties? A small lava flow will cool in a matter of hours, a large batholith could take millions of years.

Sedimentary rocks can become igneous through a process called melting and solidification. When sedimentary rocks are subjected to high temperatures and pressures deep within the Earth's crust, they can melt and form magma. This magma can then cool and solidify to form igneous rocks.
Basically, all intrusive igneous rocks have large crystals. Because they are intrusive, they take a long time to cool down, and so there is a lot of time for crystal growth. That said, the biggest categories of intrusive igneous rocks are: Peridotite (ultramafic) Gabbro (mafic) Diorite (Intermediate) Granite (silicic/felsic) Granite is the most common one in the continental crust.
When rocks cool below Earth's surface, they solidify and form igneous rocks. These rocks are classified based on their cooling rate and mineral composition, resulting in different types such as granite, basalt, and diorite. The cooling process can take thousands to millions of years, and it leads to the formation of distinct crystal patterns within the rock.
It will for an intrusive igneous rock. They usually take longer to cool and have more coarse grains.

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.
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.

It varies with the type of rock being formed. Some igneous rock is formed in a matter of minutes; some sedimentary rock is formed in processes requiring many millions of years.

Heat and pressure
It can take as many years as it needs to. It all depends on what kind of weathering occurs, and how big the grain size is.
Gabbro forms when magma cools and solidifies beneath the Earth's surface. The exact time it takes to form gabbro can vary based on factors such as the cooling rate of the magma and the depth at which it solidifies, but it generally ranges from thousands to 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.
