Question
minerals such as hematite that indicate liquid water once existed? (There are more questions from Chapter 6 on the next page!) See sections 7-1 to 7-13 in Chapter 7. Answer these questions: 7. What is the cause of the heating of magma and volcanos that erupt on Jupiter's moon lo? Some choices are tidal forces, radioactivity inside the moon, magnetism coming from Jupiter, or sliding of layers inside the moon. 8. What causes long cracks, swirls, and ridges on the surface of Jupiter's moon Europa? Some choices are comets striking Europa for millions of years, movement of ocean water below, motion of molten rock underground, or radioactive heat coming from Europa's core. 9. What material composes most of the volume of planets Jupiter and Saturn? Choices: liquid water several types of ice, solid rock, hydrogen & helium, oxygen & nitrogen undergmound or n ontve heat coming m of molten rock 10. Saturn has much brighter rings around it than Jupiter has. This is because Saturn's rings are made of what material? See sections 8-3 to 8-9 in Chapter 8 for these questions 11. Comets have tails of gas and dust that come off them. If a comet is moving away from the Sun, will the comet's tail be following behind the comet or will it be proceeding ahead of the comet?Explanation / Answer
7) Magnetism coming from jupiter
The jupiter's moon Io is very close to the planet and that is why gravitational forces exists between the two celestial bodies. the magnetic lines created by this gravitational force is enough to heat the interior of the moon and which causes the flow of magma followed by volcanic eruptions.
8) Movement of ocean water below
Europa is mostly icy layered. it is considered that large ocean lies beneath the the surface of europa and since it is close to Jupiter so gravitational effect causes tidal waves to occur and movement of ocean water below the Europa's icy surface causes long cracks, swirls.
9) Hydrogen and Helium
the planets saturn and jupiter mostly made up of gasesous and liquid hydrogen and helium which surrounds the rocks and ice in its core.
10) water ice and rocky materials.
