Create an image that visually illustrates the concept of density in relation to terrestrial planets and gas giants in the solar system. Include an aesthetically pleasing scene with two representative models: one that symbolizes a terrestrial planet and one that symbolizes a gas giant. Each model should capture their general characteristics such as size and mass, without including any written text to reflect the density comparison.

[] Terrestrial planets are more dense, in part because they have so much more mass.
[] Gas giants are more dense, in part because they are so large.
[] Gas giants are more dense, in part because they have so much more mass.
