Tornadoes are storms, and thus naturally occurring.
The difference between man made and natural occurring rock is that man made is something done by man (specification) human .We made it the way it seems ex.Mt Rushmore is man made because it wasn't naturally formed.Naturally occurring happens by flood, weathering ,deposition, and etc. It happens nautically no ones touched it. Another example is the Grand CanyonGlad i could help
Aluminium is an element, it is not synthetic.
No. As it is synthetic it is man-made. A mineral must be naturally occurring and have a crystalline structure (among other requirements). Synthetic opal does not meet these criteria.
Not true minerals, as by definition, minerals are naturally occurring substances.To be a mineral it has to be a hard substance which fulfills the 4 requirements below:1. it has to be made by nature2. it has to have a crystal structure3. it has to have a chemical formula4. it cannot be made by man or plant or animalSince diamonds made in the laboratory are man-made they don't fulfill all of the requirements.No, because for something to be mineral, it has to be a naturally occurring, solid, inorganic, a definite chemical composition, and a crystal structure.Diamonds created in the laboratory are not naturally occurring.I don't think they are considered minerals
