Yes, they can. Black Holes lose mass due to a form of thermal radiation called Hawking Radiation. The process is not fully understood, but the process is able to make the black hole slowly evaporate.
No. A Black Hole is formed when a star collapses into itself. The very largest stars will explode in supernovae while the majority of stars will expand into Red Giants before eventually becoming White Dwarves and finally Black Dwarves. Stars that go supernova will often form nebulae and Neutron Stars however the very largest stars will become Black Holes. A black hole cannot appear, as it is what once remained of a star.

It is theoretically possible for a black hole to be created on Earth, but extremely unlikely. Although a black hole can be of any mass, its size would need to be smaller than its Schwarzschild radius, meaning black holes are incredibly dense; density being measured in mass per unit volume. The act of creating an object of the density of the black hole would be a significant challenge in part because it takes a vast amount of energy. Some evidence indicates there might be a natural mechanism that creates them briefly in the upper atmosphere when cosmic rays (particles) collide with air molecules; the relativistic energies of the fastest-moving cosmic rays providing the energy to create microscopic black holes. However these are not considered dangerous since they would 'evaporate' quickly. Along the same lines it might be possible to create miniature black holes in a laboratory setting, utilizing a powerful particle accelerator with massive charged particles; again the same mechanism would theoretically allow the energy of the collision combined with the mass of the particles to briefly create a microscopic black hole.
Not likely, though it is possible in theory that Earth collides with one. If there were a "regular" black hole on Earth, it would quickly destroy Earth. The possibility has been considered that microscopic black holes are created (for example, in particle accelerators), which then evaporate, too quickly to do any harm - but for now, this is still very hypothetical.
In yo momma's face.
yes they can teleport if you summon them!!
Should Earth ever collide with a black hole, it would get destroyed.
The earth would become a black hole.
It will be ripped apart - bit by bit.
The nearest black hole to Earth is V4641 Sgr and located 1600 light years away.
You cannot see a black hole when you are on Earth, unless a black hole were to absorb Earth, which even then, you would see it in a split-second before it would engulf you
Should Earth ever collide with a black hole, it would get destroyed.
well if our earth fell into the black hole it get ripped apart before reaching the singularity
The earth would become a black hole.
In that case, there will no longer be a planet Earth.
One does not simply "pass through" a black hole.
Nothing, not even light, can escape a black hole. So Earth would get caught into the black hole's path and we would be sucked up and crushed to oblivion
Earth would crumple up into tiny bits
If the Earth magically became a black hole, the moon and other satellites in orbit around Earth, would be literally ripped apart into tiny bits and swallowed by the black hole.
My Earth, as well as my Sun, would be completely destroyed if a black hole came through our Solar System. I'm not certain what would happen to YOUR Earth.
WEll, we'd die.
It depends on where the black hole appeared, but irrespective of that bit of minutia, the same things would happen on the Earth as on the Moon if a black hole appeared somewhere, that being nothing with regards to a specific person.
most likely in a long time but scientist are detecting black holes coming closer to earth.
