Yes, but only on SOLID planets, not on gas planets.
because they are not earth
Yes, other planets in our solar system can experience earthquakes, but they are called "marsquakes" on Mars and "moonquakes" on the Moon. These seismic events are caused by tectonic activity and impacts from meteorites.
No because the Earth has an internal core with tectonic plates that move.
Any planets that have plates
Usually, no. Earth is the only planet to have a molten core, which means it's Tectonic plates have something to 'Float' on and move around on. On Mars for example, the core is solid, and there are no tectonic plates, which means earthquakes aren't possible.
It is possible that every galaxy has some planets. We just are starting to detect some planets in other galaxies.
Yes, earthquakes can occur on other planets and celestial bodies within our solar system. For example, Mars experiences Marsquakes, which are similar to earthquakes but caused by the planet's internal processes. Likewise, the moon is also known to have moonquakes, which are caused by the gravitational forces between the Earth and the moon.
Because Earth is the only place where we can murder the English language and ask questions like, "Why life is possible only in earth not in other planets?"
absolutely nothing. astronomy has to do with outer space and planets. While earthquakes would be geology
It is possible, even likely, that there are other planets that could support life. We have yet to find any.
Because the planets still have gravity. Thing of an earthquake like a house settling. As gravity pushes down on the house, the house ever so slightly moves itself. The effect is amplified with planets; they are "settling" because of their own gravity.
it is possible to live on because there is water and air
