Question

how does the tectonic activity of the terrestrial planets compare with that of the gas giants?
all of the terrestrial planets exhibit or have exhibited tectonic activity, but none of the gas giants have.
all of the gas giants experience tectonic activity, but none of the terrestrial planets do.
all of the gas giants experience tectonic activity, but only one terrestrial planet has tectonic plates
all of the terrestrial planets exhibit or have exhibited tectonic activity, but only one gas giant has.

Explanation:

Terrestrial planets (Mercury, Venus, Earth, Mars) have solid rocky crusts, and all show evidence of past or present tectonic activity (e.g., Earth's plate tectonics, Mars' ancient volcanoes and fault lines, Venus' folded mountains, Mercury's scarps). Gas giants (Jupiter, Saturn, Uranus, Neptune) lack a solid rocky surface, so they cannot have the type of tectonic activity defined by crustal plate movement; there is no evidence of tectonic activity as understood for terrestrial bodies.

Answer:

All of the terrestrial planets exhibit or have exhibited tectonic activity, but none of the gas giants have.
