does a different planet have earthquke?

Answer 1

We would have to know the makeup of a particular planet before being able to answer that question. If another planet is large plates sitting on a liquid mantle, like Earth, then they probably have earthquakes. Saturn is made up of gas, so it probably doesn't.
The real question is...if other planets have earthquakes, are they called earthquakes, or jupiterquakes, neptunequakes, marsquakes, etc.?

Answer 2

Other planets (the rocky inner ones) have molten cores and plates just like ours, so it stands to reason that they would.

Pictures of Mars have confirmed that Mars definitely had seismic activity in the past (and volcanos and lots more excitement). It undoubtedly has some still today. Pictures that show shifting ridges and dunes apparently confirm this. Exactly how much is the subject of continuing study by our Mars probes.

Answer 3

Only earth can have an earthquake. Mars must have a Mars-quake and the moon must have moon-quakes. The earth's earthquakes are generally associated with tectonic plate movements and deep interior magma chambers that surface. The interiors of the moon and mars are likely too cool and inactive to support quakes similar to earth's.

Answer 4

Scientist don't totally agree, but there is evidence that there have been, and may still be "earthquakes" on Mars (="Marsquakes").

Also on the moon, although these are thought to be caused by the gravitational pull of the Earth rather than tectonic or volcanic activity as on Earth.

Answer 5

Yes. Mars has been shown to have mars-quakes. There are seismographs on the moon and mars. Only mars has shown any seismic activity, but the reason is not known.

Answer 6

probably.
