Answer

3. **b. orbital velocities**4. **d. Saturn**

Explanation

1. **Orbital velocities** are determined by a planet's distance from the Sun. Planets closer to the Sun have faster orbital velocities. Venus and Mars are closer to the Sun than Jupiter and Saturn, hence they have greater orbital velocities.2. **Gas giants** are planets that are primarily composed of gases like hydrogen and helium. Jupiter, Saturn, Uranus, and Neptune are classified as gas giants.
