U05a1 and u05a2 - Essay subject2. Why is Jupiter so much more dense than Saturn? Could a artificial satellite be smaller in size than Jupiter but greater in citizenry? Explain. Ans Jupiter is closer to sun and has over 3 times more than the mass of Saturn. Jupiter is denser than that of Saturn because of two factors. They are (i). Jupiter has relatively larger gravitation field because of its mass and rotational pressures. (ii). Jupiter has denser core of rocks and other minerals. Jupiter has heavy metals in its interior. because it is denser than that of Saturn. Yes. There could be a planet smaller in size but greater in mass than that of Jupiter. Because Jupiter is mainly made up of gas, hence any planet slightly smaller in size but made of secure material would sustain more mass than Jupiter. And also building a planet with Hydrogen and helium is like assembling the fluffy pillows one over the other. As the pillows are stacked one to a higher place the other the pillows at the bottom are compressed and hence their mutual gravitational force increases. Hence it slightly increases in its height as and when the stack size is increased but gets denser. Therefore the supererogatory mass increases the density of the planet but smaller change in mass. 4. Why does Jupiter have such(prenominal) a strong magnetic field? Describe a few features of Jupiters magnetosphere. ... Jupiters magnetosphere traps further more charged particles than Earths magnetosphere. These particles contribute to auroras and also create belts of very intense light beam around Jupiter. This is so strong that it could damage the orbiting spacecraft. Jupiters magnetic field creates a magnetosphere that surrounds the planet as a shield which protects the planet from the solar wind. 6. Briefly describe Jupiters weather patterns and contrast them with those on the other jovian planets. What is the Great Red Spot? Ans Jupiters atmosphere has several gases that distil to form clouds. Each o f these gases condenses at a incompatible temperature, leading to distinctive cloud layers at different altitudes. Jupiter has primarily three different cloud layers and Jupiters atmosphere is inhumaner at higher altitudes. About cytosine kilometers below the highest cloud lapses, the temperatures are nearly earth-like And water can condense to form clouds. Higher up, the water clouds it is cold enough for a gas called ammonium hydrosulfide to condense into clouds which produces the dark colours of Jupiter. Higher still the temperature is so cold that ammonia condenses to make an upper layer of white clouds. Like the large hurricanes occasionally airlift on Earth, Jupiter also has powerful storms. Spectroscopic observations (analysis of light) + calculations explains about the composition of clouds as follows Ammonia (NH3) crystals in top layer. Ammonium hydrosulfide (NH4SH) crystals in middle layer. Water ice in lowest layer. The colors seem to be associated with temperature. W hite zones are higher and cooler. Dark bands are lower and warmer. Comparison with other atmosphere planets Jupiter and Saturn have stripes of alternating color and wind direction. But Saturns
