Level: third year THIRD TERM TEST

Nine known planets revolve around the sun. They greatly in size, mass, temperature, rate of rotation, and composition. They are commonly divided into two groups: the inner planets (Mercury, Venus, Earth, and Mars) and the outer planets (Jupiter, Saturn, Uranus, Neptune, and Pluto). The inner planets are small and are composed primarily of rock and iron. The outer planets (except Pluto) are much larger and consist mainly of hydrogen, helium, and ice.

Mercury is surprisingly dense, apparently because it has an unusually large iron core. With only a transient atmosphere, Mercury has a surface that still bears the record of bombardment by astreoidal bodies early in its history. Venus has a carbon dioxide atmosphere 90 times thicker than that of Earth, causing an efficient greenhouse effect by which the Venusian atmosphere is heated. The resulting surface temperature is the hottest of any planet-about 477°C. The Earth is the only planet with abundant liquid water and life. Strong evidence exists that Mars once had water on its surface (and still has below the surface, in the form of ice), but now its carbon dioxide (CO2) atmosphere is so thin that the planet is predominantly dry and cold, with polar caps of solid carbon dioxide, or dry ice. Jupiter is the largest of the planets. Its hydrogen and helium atmosphere contains pastel- coloured clouds, and its immense magnetosphere, rings, and satellites make it a planetary system into itself. Saturn rivals Jupiter, with a much more intricate ring structure and more satellites, including one with a dense atmosphere- Titan. Uranus and Neptune are deficient in hydrogen compared with the two giants; Uranus, also ringed, has the distinction of rotating at 98° to the plane of its orbit. Pluto seems similar to the larger, icy satellites of Jupiter or Saturn. Pluto is so distant from the Sun and so cold that methane freezes on its surface.
