To accurately compare the tectonic activity of the planets, we can evaluate the provided statements one by one:
-
The terrestrial planets experience quakes; the gas giants do not.
- True. Terrestrial planets like Earth, Mars, and Venus experience seismic activity, while gas giants like Jupiter and Saturn do not have a solid surface and therefore do not experience quakes in the same way.
-
The gas giants have multiple plates; the terrestrial planets do not.
- False. Terrestrial planets have tectonic plates, while gas giants do not have a rigid crust or tectonic plates in the same sense.
-
The gas giants have no true surfaces, so they experience tectonic activity.
- False. Gas giants do not have solid surfaces, which means they cannot experience tectonic activity like solid planets do.
-
Terrestrial planets experience (or experienced) tectonic activity; gas giants do (or did) not.
- True. Terrestrial planets are known to have tectonic activity, while gas giants do not.
-
Mountains and volcanoes are found on the gas giants, not on terrestrial planets.
- False. Mountains and volcanoes are found on terrestrial planets. Gas giants have some cloud formations and storms but do not have solid surface features like mountains or volcanoes.
-
Activity in the molten interior of the terrestrial planets results (or resulted) in tectonic activity.
- True. The molten interiors of terrestrial planets lead to tectonic movements and geological activity.
Based on this evaluation, the accurate statements are:
- The terrestrial planets experience quakes; the gas giants do not.
- Terrestrial planets experience (or experienced) tectonic activity; gas giants do (or did) not.
- Activity in the molten interior of the terrestrial planets results (or resulted) in tectonic activity.
