Question

comparing the tectonic activity of the planets
which statements accurately compare the tectonic activity of the planets? check all that apply.
the terrestrial planets experience quakes; the gas giants do not.
the gas giants have multiple plates; the terrestrial planets do not.
the gas giants have no true surfaces, so they experience tectonic activity.
terrestrial planets experience (or experienced) tectonic activity; gas giants do (or did) not.
mountains and volcanoes are found on the gas giants, not on terrestrial planets.
activity in the molten interior of the terrestrial planets results (or resulted) in tectonic activity.

Explanation:

Terrestrial planets like Earth have solid - rocky surfaces and molten interiors which can cause tectonic activity such as quakes. Gas giants lack solid surfaces in the traditional sense and thus do not have the same type of tectonic activity as terrestrial planets. Mountains and volcanoes are found on terrestrial planets due to tectonic activity, not on gas giants. Also, the presence of multiple plates is characteristic of terrestrial planets like Earth, not gas giants.

Answer:

• 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.
