Question Completion Status QUESTIONT The Jovian, or gas giant, planets all have cmpared to the terrestrial planets. O a-large masses, high average densities, and higher abundances of light elements like hydrogen and helium O b large masses, low average densities, and higher abundances of light elements like hydrogen and helium O C small masses, high average densities, and higher abundances of heavy elements like iron and nickel. O d large masses, high average densities, and higher abundances of heavy elements like iron and nickel. QUESTION 2 The planet in our solar system that could float in water (because its density is less than that of water) is 0 a. Venus O b. Mars O C. Jupiter O d. Saturn

Explanation / Answer

1) the answer is B, low density, high masses the terrestrial planets high density, The terrestrial planets (Mercury, Venus, Earth, and Mars) resemble the Earth in size and density. They have a solid, rocky composition and they rotate about their own axes at the same rate or slower than the Earth

The great, or Jovian, planets (Jupiter, Saturn, Uranus, and Neptune) are much larger than theEarth and have much lower densities. Their compositions are largely gaseous and they rotate more rapidly than the earth. Pluto’s large orbit is highly elliptical and more steeply inclined to the ecliptic than that of any other planet. Its physical properties are different from both the great planets and the terrestrial planets  

2) answer is D, Saturn is the second largest planet in the solar system.Its equatorial radius is 60,268 km and its mean density is merely 687 kg per meter cube(the lowest in the solar system and less than that of water). Thin concentric rings in its equatorial plane give the planet a striking appearance. The obliquity of its rotation axis to the ecliptic is 26.7, similar to that of the Earth Consequently, as Saturn moves along its orbit the rings appear at different angles to an observer on Earth.  

Its mean density of 687 kg per m3 is the lowest of all the planets, implying that Saturn, like Jupiter, is made up mainly of hydrogen and helium and contains few heavy elements. The planet probably also has a similar layered structure, with a rocky core overlaid successively by layers of liquid-metallic hydrogen and molecular hydrogen
