Solar System Chemistry: Understanding the Sun & Planetary Composition

Delve into the chemistry of the solar system, from the Sun's spectrum to the composition of chondrites and Earth's mantle. Explore the prevalence of basalt and granite, shield volcanoes on Earth and Mars, and the unique features of our planet's surface. Discover how ice can be a rock in the outer solar system and the exotic forms it can assume under high pressure. Unravel the mysteries of Io, Titan, and Uranus through an artist's conception and learn about comets as leftovers from the outer solar system.

  1. Recipe For a Small Planet

  2. Understanding the Chemistry of the Solar System Begins with the Sun

  3. The Solar Spectrum

  4. Chemistry of the Sun

  5. Chondrites are a Close Match to the Sun’s Composition

  6. Chondrites are Depleted in Gases, a bit Richer in Metals, than the Sun

  7. Mega-Impacts may Have Mixed Materials From Different Planets

  8. Earth’s Mantle is Basically Chondritic in Composition

  9. We Can Expect Basalt to be Very Abundant in the Universe

  10. Anorthosite

  11. With Some Very Simple Science, We Can Understand the Geology of the Moon

  12. Earth’s Interior is in Motion

  13. Basalt Forms Earth’s Ocean Floors as Plates Pull Apart

  14. Basalt Builds Great Shield Volcanoes

  15. Satellite View of Mauna Loa

  16. Olympus Mons on Mars is also a Shield Volcano

  17. Much of Venus Seems to be Covered With Basalt

  18. So Far, Granite is Unique to the Earth

  19. Granite is the Sign of an Internally-Active Planet

  20. Deep in the Earth, Under High Pressure, Eclogite Forms

  21. Earth is Unique in Many Ways

  22. Earth’s Unique Surface

  23. Our Pleasant Earth is a Remarkably Hostile Environment for Rocks

  24. Where It’s Cold Enough, Ice Can Be a Rock

  25. In the Cold Outer Solar System, Worlds are Made of Ice as Well as Rock

  26. Under High Pressure, Ice Assumes a Number of Exotic Forms

  27. Io

  28. Artist’s Conception of a Scene on Io

  29. Titan

  30. Uranus (Artist’s Conception)

  31. The Narrow Rings of Uranus

  32. Comets are Leftovers from the Outer Solar System
