Yes, the main difference is between a sedimentary rock and a metamorphic rock.
A sedimentary rock is formed from various sizes of rock or rock particles (eroded from older rocks) that have been deposited by wind or water over time. The weight and pressure of subsequent deposits results in the squeezing out of water from the lowest depositional layers, and these layers may become cemented together as a solid rock.
Metamorphic rocks are formed subjecting an existing rock (sedimentary or volcanic), to heat and or pressure after it was formed. This 'cooking' changes the rock, giving it new fabrics, textures and minerals.
Both sedimentary and metamorphic rocks can be inclined with respect to their fabrics (beading in the case of sedimentary rocks), this is not a distinguishing feature.

Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.

They are both rocks
Most regional metamorphic rocks are formed in conditions within this range of geothermal gradients, passing through the greenschist facies to the amphibolites

Yes. A sedimentary rock, over time, can become buried under layers of newer rock. The heat and pressure from being in between layers of old and new rock, will change it from sedimentary to metamorphic.
They are both rocks. Sedimentary can contain metamorphic rocks. and vice versa.
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
Metamorphic rocks are made from cooling lava, Igneus rocks are made by heat and presure, and Sedimentary rocks are made by sand and/or other tiny broken off peaces of rocks being presurised together forming one single rock
