According to the chart below, how do the gas giants differ from the terrestrial planets? (3 points) image describing the composition of the terrestrial planets (mercury, venus, earth, and mars) and the gas giants (jupiter, saturn, uranus, and neptune) of our solar system. mercury is composed of 45 percent core, 50 percent mantle, and 5 percent surface crust. venus is composed of 15 percent inner core, 20 percent outer core, 60 percent mantle, and 5 percent surface crust. earth is composed of 5 percent inner core, 35 percent outer core, 55 percent mantle, and 5 percent surface crust. mars is composed of 50 percent inner core, 45 percent outer core, and 5 percent surface crust. jupiter is composed of 5 percent rock, 15 percent water, 60 percent metallic hydrogen, and 20 percent hydrogen gas. saturn is composed of 10 percent rock, 20 percent water, 30 percent metallic hydrogen, and 40 percent hydrogen gas. uranus is composed of 30 percent rock, 35 percent water, and 35 percent hydrogen. neptune is composed of 15 percent rock, 60 percent water, and 25 percent hydrogen gas. select one: a. the gas giants do not have solid surfaces. b. the gas giants have an iron core. c. the gas giants lack hydrogen gas. d. the gas giants do not contain water.
