Is zircon manmade?
Zircon itself is a naturally occurring mineral, so it is not manmade. However, some zircon gemstones undergo treatments, such as heat treatment, to enhance their color or clarity, but the base mineral itself is natural.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.
What objects can give off UV rays or waves besides the usage of the sun?
Some artificial sources that can emit UV rays or waves include UV lamps, tanning beds, welding arcs, and certain types of light bulbs and lasers. These sources can potentially emit harmful UV radiation and proper precautions should be taken when exposed to them for prolonged periods.
What type of energy do quasars give off?
Quasar actually means quasi-stellar radio sources so we thought that it was giving off radio waves but we did not put into account the redshift that causes the stretching of the wavelength meaning that it most likely gives off microwaves.
What are some examples of sound waves?

Definition of siesmic waves and 3 examples?
Seismic waves are the waves of force that travel through earth or other elastic bodies. eg: Result of an earthquake ,explosion or some other processes that imparts forces
Are lakes manmade?

Is nothing free if it's manmade?
Some stuff can be free if manmade, although, sooner or later, it will come up in somesort of cost.
What are sources of ultraviolet waves?
Sources of ultraviolet waves include the sun, tanning beds, black lights, some types of lasers, and certain industrial processes such as welding and mercury vapor lamps. UV lamps used for disinfection and certain medical treatments also emit ultraviolet waves.
Are bridges manmade?
Most bridges are manmade, built in the location where they are required. Some natural bridges of rock or timber exist in wilderness areas.
Are clay banks manmade?

Why the landforms are not flat?
Some landforms are flat and some are raised areas because it is created by nature and it is not manmade .
What are some manmade objects in the mesosphere?
Some manmade objects found in the mesosphere include weather balloons, research rockets, and debris from spent rocket stages. These objects help scientists gather information about the Earth's atmosphere and conduct various experiments.
What are some examples of energy transfers by waves and their sources?
Light energy from the Sun is transferred to Earth through electromagnetic waves. Sound energy is transferred through air as mechanical waves created by vibrating objects such as a guitar string or vocal cords. Ocean waves transfer energy from wind to the water surface to create wave motion.
What emits ultraviolet light waves?
Some sources of ultraviolet light waves include the sun, fluorescent light bulbs, tanning beds, and some types of light fixtures and lasers. UV light can also be emitted by certain materials as a result of chemical reactions or other processes.
