Question

14 which characteristic do all the planets in our solar system have in common? a angle of axial tilt b direction of revolution c percentages of atmospheric gases d features of a rocky crust

Explanation:

• Option A: Planets have different axial tilts (e.g., Earth ~23.5°, Uranus ~98°), so this is not common.
• Option B: All planets in the solar system revolve around the Sun in the same direction (counter - clockwise when viewed from above the Sun's north pole), this is a common characteristic.
• Option C: The percentages of atmospheric gases vary greatly (e.g., Earth has N₂, O₂; Jupiter has H₂, He), so this is not common.
• Option D: Gas giants (Jupiter, Saturn) do not have a rocky crust like terrestrial planets, so this is not common.

Answer:

B. Direction of revolution
