Continue from the birth of our sun. After the nuclear fusion took place it blew the remaining gas from the inner solar system out to a distance beyond the asteroid belt. This
Th inner planets are rocky because as the Sun and planets formed the more volatile elements could not condense into droplets near to the hot Sun. Thus the inner planets are made form stuff with a high melting/boiling point and the outer planets (where it was cooler) are made from the gases.
the inner planets have rocky surfaces
All the inner planets are like that
The inner planets are rocky and the outer planets are gas giants.
All the inner planets are rocky or terrestrial planets.
The Rocky Planets, or Inner Planets, include Mercury, Venus, Earth, and Mars.
Mercury is a rocky planet. The inner planets (first four planets from the sun) are rocky planets (which means that you could stand on them) and are the smallest. While the outer planets (last four planets from the sun) are gas planets and the biggest.
Terrestrial Planets, or Rocky Planets.
The inner planets (Mercury, Venus, Earth and Mars) are rocky. It is the outer planets (Jupiter, Saturn, Uranus and Neptune) that are gas planets.
Inner Planets: Are rocky planets and smallOuter Planets: Are gas giants and giant
they are rocky and have terrain areas the rest of the planets are all gas
Terrestrial Planets, or Rocky Planets
Inner planets small and rocky. Outer planets big and gassy.
