Not that much, about 5%. You could check other textbooks though.
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.
Well if you take into acount that metamorphic rock is formed by applying heat and pressure to sedimentary rock the answer becomes quite clear; the pressure is created by the tectonic plates colliding and the heat source is from the molten rock that is pushed close to the surface due to the collision. :)
It is more likely that igneous and metamorphic, or igneous and sedimentary rocks would have something in common than sedimentary and metamorphic. The reason is because the processes involved in making metamorphic rocks is completely different than the processes needed to make sedimentary rocks. Only high temperature, high pressure minerals such as olivine, pyroxene, amphibole can withstand these kinds of conditions. Take quartz and feldspar, two of the most abundant minerals found in sedimentary rocks, these minerals would not be found in abundance in metamorphic rocks because they are not high temperature, high pressure rocks. But the most simple answer is that all the major groups of rocks are made of minerals. Metamorphic has high pressure and Igneous does to and both made from a particle called magma.
No. Metamorphic rock froms from processes that take place in the solid state. Rocks that form from molten material are igneous.

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.
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.

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
Most metamorphic processes take place deep within the Earth's crust or upper mantle, typically at depths between 10 and 50 kilometers. These processes are driven by heat, pressure, and chemical reactions that transform existing rocks into new types of rocks without completely melting them. Metamorphism often occurs at convergent plate boundaries where tectonic forces cause intense heat and pressure.
Magmatic fluids coming from the intrusive rock may also take part in the metamorphic reactions.
