What will happen if you replace moon with a black hole of the same mass?

    Not much. Black holes pull things in towards them because of their large mass. A black hole with the mass of the moon would be a tiny black hole. Not large enough to do any damage.

      No. Tidal forces fall off at 1/r^3. They will be the same as the normal, not black hole, moon.

    Nothing would change at all. We just wouldn't see a moon or the black hole in our sky.

    There would not be any moonlight - some animals and plants use the full moon to trigger reproduction. Those lifeforms would die out.

    The tides would continue since they are the result of the moon's gravity and that would not change.

    Will be destroyed from the sun in very few minutes maybe, and the extra particles will make the other "before" planets, moons, asteroids, all smaller things but bigger and less dense g/mol than it, larger in volume, with all particles to elements created that will survive the burst. Nearest most in the way further of sun.

    Sun will do Similar thing (as viewing, but nothing common) as the nearest quasar is killing and feeding itself at same time with inside replacement of the past combustion, with shredding, sending stronger particles as beam out far - without enough power to contain all.

    So what will happen? 

    If the moon replacement is at position between this planet and sun, on the line-place sun-bh-planet 'place' will have huge mountain as Eiffel Tower (but 10 times larger than moon) of particles forming into elements.

    If this planet is out of the path, it will be next planets away from sun on its way. But any way, extra particles go away further until balance!

    Micro black holes with the mass of the Moon would evaporate very quickly. If a black hole with the mass of the Sun replaces the Sun, the planets would keep orbiting as usual. Earth's atmosphere would freeze.

    If it has the same mass, the acceleration oof gravity and the force remain the same.

      Didn’t down vote you, but as an FYI, a black hole the mass of the moon would not evaporate quickly. It would take about 10^45 years - a very, very long time.

    It would be so small you couldn't see it and there would be no effect as the gravitational effect would be the same as the moon.

    A "blackhole" of the same mass would not be a black hole because it would lack sufficient mass to qualify for that designation.
