Obsidian is an igneous rock. Rocks are not man-made. Man-made substances that are similar to rock include concrete and cement.
No, porcelain is not a type of sedimentary rock. Porcelain is a type of ceramic material made by heating materials such as clay at high temperatures. Sedimentary rocks are formed by the accumulation of sediments over time, which are then compacted and cemented together.
Concrete is a man-made conglomerate composed of pieces of rock in a matrix of cement, which is itself made from limestone. It is just as much part of the rock cycle as any naturally occurring rocks.
There are man made imitations but real granite is a natural rock.

to make creative things out of rock that people rarely think about
Sidewalks are made of concrete, which is not a rock. Concrete is a man-made construction material composed of Portland cement, various crushed rocks, sand and water.
Concrete is a man-made conglomerate composed of pieces of rock in a matrix of cement, which is itself made from limestone. It is just as much part of the rock cycle as any naturally occurring rocks.
Artificial rocks, such as concrete or bricks, are not formed by the natural rock cycle. These rocks are man-made through processes like mixing cement, shaping, and hardening. They do not undergo the typical geological processes like weathering, erosion, and lithification that form natural rocks.
The Old Man of the Mountain was a series of rocky ledges composed of granite, a type of igneous rock. Granite is a common rock type found in mountainous regions due to its durability and resistance to weathering.
No, it is an organically produced rock but it is not man made.
No it is not man made
No, concrete is not a rock. Concrete is a man-made material composed of a mixture of cement, water, and aggregates such as sand and gravel. Rocks are naturally occurring solid materials composed of minerals.
