Non crystalline.
yes
There are three major types of rocks: igneous, metamorphic, and sedimentary. Rocks are classified based on the process by which they were formed. Sedimentary rocks form from sand, dust, and tiny rock particles that are fused by water and extreme pressure over time. Igneous rocks form from cooled magma or lava; depending on how fast they were cooled and solidified, igneous rocks may or may not go through crystallization. Metamorphic rocks are rocks that changed from either sedimentary rocks, igneous ones, or other metamorphic rocks. These generally form from wind, water, or chemical erosion.
Igneous Rocks are formed. Obsidian is a volcanic glass, go to wikepidiea and search "list of rocks" and it will come up with all the different igneous, metamorphic, and sedimentary rocks and what they are.
Sedimentary rocks can change to igneous rock when it goes through the rock cycle so a sediment can move to igneous rock where there is a volcanic activity happens making the the sediment get heat and pressure that makes igneous rock.So when you do the rock cycle you can go from igneous rock to a metamorphic rock.
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
Obsidian goes through the rock cycle the same way other rocks go through the rock cycle, either through metamorphosis, weathering and erosion and subsequent lithification into sedimentary rock, or by melt into another igneous rock.

yes it can...this is true
lava and/or magma cools and forms igneous rocks. igneous rocks go through weather and erosion which forms sediments. these sediments are collected and compacted. this causes sedimentary rocks. the sedimentary rocks go through weather and erosion as well as being exposed to heat and pressure. this causes metamorphic rocks. metamorphic rocks go through heat and pressure and then they melt and become lava or magma again. this is called the rock cycle.
Sedimentary or igneous rocks often go through the change of metamorphism.

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.

Metamorphic rocks are formed from igneous, sedimentary and older metamorphic rocks that are introduced to extreme temperature and pressure. Because of the extreme temperature and pressure, rocks go through a significant chemical or physical change, turing them into metamorphic rocks.
Yes. All rocks are at some point in the rock cycle depending on its own composition and the environment it is in (it can be subject to weathering to form sedimentary rocks, high temperature and pressure to form metamorphic rocks, or melting and cooling to form igneous rocks)
