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.
Sedimentary rocks form from the accumulation of sediment such as sand, silt, or clay. For sedimentary rocks to form, there must be pre-existing rocks that weather and erode to produce sediment. Therefore, sedimentary rocks could not have been the first rocks on Earth as they require the presence of older rocks to form.
The process through which rocks change form is known as the rock cycle. It involves the transformation of rocks from one type to another over long periods of time through processes such as weathering, erosion, and metamorphism.

No, metamorphic rocks form over thousands to millions of years through the intense heat and pressure acting on existing rocks. The exact time it takes depends on the specific conditions present during the metamorphic process.
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.
It takes thousands of years to form because the rocks have to break down into little pieces.
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.

Igneous rocks can form quickly in days to months from cooling magma, sedimentary rocks can take hundreds to millions of years from weathering and deposition of sediments, and metamorphic rocks can form over millions of years from existing rocks under high heat and pressure.

no
It doesn't necessarily matter what the minerals are, as long as they form from cooling magma or lava. Igneous rocks are formed by the solidification of cooled magma (molten rock). They may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
Rocks form soils due to weathering by wind, sun, rain and ice.
No, it can form on land also. Just as long as they go through lithification
