3. Jovian planets have layered interiors with very high internal temperatures and pressures. The core’s are about 10 times the size of Earth’s consisting of metals, rock, and hydrogen compounds. Jupiter, on the other hand is made almost entirely of hydrogen and helium
4. Because of its large size, Jupiter loses heat very slowly. The planet is still slowly contracting. Contraction converts gravitational energy into thermal energy. Neptune also uses contraction as a way of generating internal heat. Saturn, on the other hand, has liquid helium raining into its interior and it has a less extreme core temperature than Jupiter.
6. Different types of clouds reflect different types of light. Jupiter 's clouds reflect brown and red light. Saturn 's …show more content…
A meteor is a flash of light caused when a space particle burns up in our atmosphere. A meteorite is what we call when a rock from space actually lands on Earth. Primitive meteorites are essentially unchanged since the birth of the solar system. Processed meteorites are fragments of larger asteroids that underwent differentiation.
8. The Kuiper Belt is a ring of comets that orbit the Sun beyond the orbit of Neptune. The Oort cloud is located in the the outer solar system and the comets orbit around the Sun.These were developed from planetesimals that were thrown outward after their formation between the Jovian planets. However the Kuiper Belt comets that formed still remain in the outer regions of the planetary realm.
14. If Jupiter did not exist, the threat from asteroids might be much smaller, since the objects that make up the asteroid belt might instead have become part of a planet. On the other hand, the threat from comets might be much greater. By catapulting asteroids and comets in Earth’s direction, Jupiter and other jovian planets have caused cosmic collisions that helped shape Earth’s destiny.
25. The asteroid belt lies between the orbits of Mars and Jupiter. This is due to orbital resonances with
