Is Earth is the only planet in the solar system known to have plate tectonics?
Question:
Answer:
Ongoing and widespread, no. However..
Venus shows evidence of similar movements, but not as worldwide as Earth. On Mars, Valles Marineris may have been tectonic in origing, and the moon Miranda, of the planet Uranus has a curious feature which looks like a part of itself sort of turned upside down (probably from a collision).
no
Yes. Venus and Mars have a similar composition to the Earth, but they lack independent plates of crust.
Venus has ancient signs of plate movement.
Mars, only a stretch mark at Valles Marineris.
Ganymede shows some signs of plate tectonics
The jury is still out on what the heck happened to Miranda.
Enceladus and Europa show signs of stretching, but no subduction.
