1. SQ3R Reading Guide Name: CHAPTER SECTION: Survey/Question : Do this BEFORE you read. Turn Headings into questions: How are Terrestrial and Jovian planets different? How did the solar system form? What vocabulary words do I notice? Read: this space is for me to take notes. I am looking for: 1) Answers to my questions and 2) Important information or details 3) Use bold sub headings found in each section Know Think I know Unsure Terrestrial Jovian Nebula Planetesimal How are terrestrial and Jovian planets different Size: Terrestrial planets are smaller than Jovian planets Density: The terrestrial planets are 5 times more dense than water… Jovian are 1.5 times more dense… TERRESTrIAL ARE MORE DENSE Rate of Rotation: Jovian planets have a higher rate of rotation, they have shorter days. Interiors of Planets: The planets are made of gas, rock, and ice. Terrestrial planets are made of silicates and metals…many have ice made of water Jovian Planets are made of gases such as Hydrogen and helium….they have ices that are methane and ammonia Jovian planets have metals at their core Atmospheres of Planets: The Jovian planets have very thick atmospheres… made of hydrogen, helium, methane…. The terrestrial planets have thin atmospheres made of water vapor, carbon dioxide, Atmospheres are determined by the density of the planet and how Distance from the Sun: Terrestrial planets are closer to the sun, Jovian are farthest away… How did the solar system form? 1.The solar system formed from a solar nebula….a nebula is a cloud of gas and dust 2.A protostar forms as gravity pulls the nebula together 3.The Sun forms from the protostar 4.The planets from from the disk that is found around the newly formed sun 5.Each layer of the disk forms a different planet, there was once 100 planets now there are 8

3. SQ3R Review: Write 3 questions you will use to review and answer them Reread and Recite: Rewrite as much of the front side of the assignment as you can from memory. By test time you should be able to rewrite the entire front side. Write VOCAB HERE! CharacteristicsJovianTerrestrial Size50-140 times larger than the earth Up to 10 times smaller than the earth Distance from the sun5-30 times farther than the earth Closer to the sun than the earth DensityNearly the same density as water 4-5 times more dense than water AtmosphereMethane, ammonia, hydrogen, helium: very thick Thin atmospheres of mostly carbon dioxide Composition of planetRocky cores of iron, most of the planet is made of Methane, ammonia, hydrogen, helium: Rocky core, mantle crust, Rate of rotation Up to 2 times faster than the earth Slower than 24 hours per turn
