Question

practice it! drag and drop the words or phrases that best complete the paragraph. the \boxed{} planets have far more moons than the inner planets. this mainly due to outer planets having greater \boxed{}. the higher the mass, the more \boxed{} an object has. therefore, the planets with the most mass are able to hold more \boxed{} in their orbits. options: gravity, moons, outer, mass. chart: jupiter: distance from sun (million km) 778.4, mass (earth=1) 317.83, moons 79; saturn: 1426.7, 95.16, 62; uranus: 2871, 14.54, 27. (images of jupiter, saturn, uranus)

Explanation:

1. The first blank: From the context and the table (showing Jupiter, Saturn, Uranus as outer planets with many moons), we know it's "outer" as outer planets have more moons than inner.
2. The second blank: The sentence relates to what outer planets have more of, and the table shows their mass is large. Also, the next sentence connects mass to another factor, so this is "mass".
3. The third blank: The relationship is "higher mass → more...", and in physics, more mass means more gravity (gravitational pull), so this is "gravity".
4. The fourth blank: The planets with more mass (and gravity) can hold more "moons" in their orbits, which matches the first part about outer planets having more moons.

Answer:

1. outer
2. mass
3. gravity
4. moons
