Why is a year on Mars longer than a year on Earth?
Uranus
Mercury
rocky
Mercury’s orbit is the shortest in the solar system.
Earth is much closer to the sun than the gas giants are.
Mars is farther from the sun than Earth is
Uranus, which has a surface gravity that is 79% of Earth’s
Gas giants are more massive than Earth and thus have greater gravitational forces, so they could attract more objects
Chase is making a model of the solar system. He is labeling the planets as terrestrial planets and gas giants. Which planet should he label as a gas giant?
Uranus
Mercury
rocky
Mercury’s orbit is the shortest in the solar system.
Earth is much closer to the sun than the gas giants are.
Mars is farther from the sun than Earth is

Weight depends on the force of gravity. The greater the gravitational attraction of a planet, the more an object weighs on that planet. On which planet would you weigh less than you would weigh on Earth?
Uranus
Mercury
