The question makes no sense. Altitude has nothing at all to do with black hole formation. "Altitude" really only has any significant meaning in terms of Earth and humans, and it is as far as we know absolutely impossible to "make" a black hole at any altitude.
Yes. A black hole is a collapsed star.
the black hole is a matter in outer space that is made by the force of gravity
no.
the death of a star
Yes the black hole can be destroyed. However, man-made objects cannot resist the gravity without getting sucked in. The only thing that can destroy a black hole is time in a process called Hawking Radiation in which the black hole evaporates over time. The smaller the black hole, the faster the process.
A supermassive black hole.
That is not yet known for sure. Most large galaxies have a supermassive black hole in their center. It is known how a massive star can convert to a black hole, but it is not currently known how such a black hole would acquire such a huge mass since its creation.
A giant star that ends it life in a supernova
A supermassive black hole.
Black holes are created when a star runs out of fuel and collapses. That is a nova, A black hole is made when a neutron star goes SuperNova and the energy tears a hole in space, creating a strong gravitational singularity.
Black hole - although not really a starNeutron StarPulsar
Black holes are not composed of matter, and do not have a chemical formula.
