Terrestrial planets are mainly composed of while jovian planets are made dominantly of a. rock and metals; volatiles b. refractory materials; volatiles and metals c. volatiles and metals; refractory materials d. volatiles; rock and metals

The Terrestrial Planets are those that are closest to the Sun: Mercury, Venus, Earth and Mars. Among its main characteristics is the fact that they have a metallic core and a silicate mantle that surrounds them. In addition, they have rocks, craters, mountains, valleys and volcanoes on its surface.

on the other hand, Jovian Planets (Jupiter, Saturn, Uranus and Neptune) are classified as "gas and ice giants", because they are mainly composed of gas and volatile materials. For example, Uranus and Neptune have higher concentrations of methane (hence its bluish color) and some heavier elements such as oxygen, carbon, nitrogen, and sulfur, while, Jupiter and Saturn have a mixture of hydrogen that gives off a red aspect.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
