That is because metamorphic rock is formed by parent rocks that are either sedimentary rock or igneous rocks and we can use the former rock type to distinguish the type of metamorphic rock, marble was igneous rock exposed to high pressure or temperature.
While the other two type of rocks are formed initially by sedimentation and volcanic movements and has no parent rocks.
Answer: Summary. Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals. Texture reflects how an igneous rock formed.

Explanation:
Answer: Turn off unnecessary lights in the house and try not to waste energy
Explanation: I would most definitely try not to waste energy and electricity by keeping things like lights that don't need to be on, turning them off, unplugging things when I'm not using them, like a tv, a toaster, fans, printers and other appliances that don't need to be plugged in when not being used. This helps save energy in return.
hope this helps in some way.
