Study the solar system data tables 1 and 2.These tables provide information scientists believe to be true about the planets in the solar system.By looking at the data in these tables you should be able to find some patterns, similarities, and differences among the planets in our solar system. Questions: 1. Use three physical properties (diameter, mass, density, surface temperature, etc.) of the planets in the solar system to group them into general categories or in general ways. 2. Write any general statements (more than one (1)) you can draw from your study of the properties that could be cited as patterns in the solar system. 3.Which planet would float in water? ___________________________________________________ (Hint: Less dense objects float in denser fluids, the density of water= 1g/cm³) 4. How long is a day on Jupiter? ____________, 5. on Venus? _____________, 6. on Mars? ____________ 7. How many
years go by before one
year has passed? _________________ 8. Which two planets account for 90% of the total mass of all of the planets? ________________________________ and __________________________________ 9. Refer to Table 2. Which planet seems unusually hot considering its distance from the sun? ___________________ 10. By looking at the data, suggest a reason for this extreme hot temperature. 11. Table 3 provides information about the density of common materials found on Earth.Compare the densities of metal, rock, ice, and gas to the average planetary densities in Table 1.What can you guess about the composition of each of the planets?Answer this by filling out Table 4.(Hint: You can answer in terms of mostly metal, rock, ice, gas; or combinations of these.)

Using the data in Table 1 and Table 2 make a three-line graph for each of the sets of data listed below.Please also see the Lab 10 Graph to Accompany Planets Lab to complete this question. Please submit graph as an image file such as JPG, GIF, or PNG. Thank you! Use a different color or symbols for each line. Average

What does each line tell you?(This answer should be more than just the obvious of what data you just graphed. You need to explain what you graphed.) 14. What trends becomes more clear or obvious?(list more than one (1) trend) 15. What stands out as a result of graphing the data? El Centro College
