be correct? Give one good reason why this model made sense at the time. (3 marks)
5. Please briefly explain why rocky planets (e.g. Mercury, Venus, Earth, Mars) all occur on
the 'inner' orbits (orbits closest to the Sun), while the gas giants (e.g. Jupiter, Saturn,

of you probably will – and should!). You do not have to quote exact quantitative values,
but any figures you state should be presented in relative terms (e.g. compared to Earth).
Some facts you may want to list include the planet's size, moons, atmosphere, surface

NOT fictional attributes you developed for your brochure. (7 marks – 5 marks for facts,
