Geology is the multi-disciplinary science that studies the earth and its history. We live on a dynamic planet that is constantly changing. Our ability to survive as a civilization and as a species is intricately linked to the geologic processes that shape our earth, form its natural resources and allow it to recover from the abuse that our society heaps upon it.

  • Planetary Geology (Part of Chapter 9): General Processes Affecting the Terrestrial Planets (And the Moon)
    Planetary Geology (part of Chapter 9): General Processes Affecting the Terrestrial Planets (and the Moon) Many geological features on planetary surfaces are shaped by processes within the planet’s interior. The interior of a terrestrial world is divided into three layers of differing densities and chemical compositions: core of high-density metal, mantle of moderate- density rock, and crust of low-density rock. Although we see molten rock (lava) coming out of the Earth, only a thin layer near the top of the mantle is partially molten. However, the solid rock within planets can flow like a liquid over periods of millions of years at speeds of around 1 cm per year. The crust and very top part of the mantle do not deform or flow easily, they are called the lithosphere. The thickness of a planet’s lithosphere affects how easily it can be fractured and rearranged into mountains and valleys, and how easily lava can be erupted onto the surface. Interior heat causes geological activity. Terrestrial worlds were heated during their formation due to accretion and differentiation, and are still heated today by radioactive decay. They are slowly cooling down, with heat moving up through the mantle by convection, up through the crust by conduction, and radiating out to space. Larger planets retain heat for longer than smaller planets, so larger planets are more geologically active. If a rapidly-rotating planet contains a layer of electrically conducting fluid, such as a liquid metal core, then it will have a magnetic field. This magnetic field can protect its atmosphere from the solar wind.

The Dissertation of Christopher Thomas Reinhard is approved: ________________________________________________ ________________________________________________ ________________________________________________ Committee Chairperson University of California, Riverside ! ! ACKNOWLEDGEMENTS It goes without saying (but I’ll say it anyway…) that things like this are never done in a vacuum. Not that I’ve invented cold fusion here, but it was quite a bit of work nonetheless and to say that my zest for the enterprise waned at times would be to put it euphemistically. As it happens, though, I’ve been fortunate enough to be surrounded these last years by an incredible group of people. To those that I consider scientific and professional mentors that have kept me interested, grounded, and challenged – most notably Tim Lyons, Rob Raiswell, Gordon Love, and Nigel Hughes – thank you for all that you do. I also owe Nigel and Mary Droser a particular debt of graditude for letting me flounder a bit my first year at UCR, being understanding and supportive, and encouraging me to start down the road to where I’ve ended up (for better or worse).

  • My Life and Stryper Revealed
    HONESTLY My life and Stryper revealed. By Michael Sweet Founding member, singer, songwriter, and guitarist of the pioneering Christian rock band Stryper tells his life story…. Honestly. with Dave Rose and Doug Van Pelt © 2014 Big3 Records ONE I drink. Occasionally I smoke. If you ask my wife, my kids, my tech, my agent or my manager they'll all tell you that I curse more than I should. I've fooled around with women on tour buses. I’ve been arrested for indecent exposure. I've been reckless with money to the point of bankruptcy. My favorite bands are The Beatles, Van Halen and Judas Priest. I was pissed at God when my wife died of cancer and I despise religion. I am a Christian. I'm Michael Sweet. I’m a singer, guitarist, songwriter, producer and a founding member of the pioneering Christian rock band Stryper. We've sold almost 10 million records to date and were the first Christian band to air on MTV, and to have four #1 videos. We even had two top-10 videos at the same time, back when MTV actually played music videos. We've played soccer stadiums and biker bars, sometimes in the same week. Despite having done all of that, I'm still often known as the Bible-Tossing- Yellow & Black-Bumble-Bee guy. The Jesus guy. The 80's hair/glam Christian metal guy. An irrelevant joke. Or, even worse-- sometimes I'm not known at all. So who am I? I'm a guy that grew up in Southern California – sort of a surf punk kind of guy who absolutely loved music.

Although the Earth provides a rich tapestry for geologists, other planetary bodies in our Solar System are equally worthy of study. Many of the same processes that operate on Earth modify these worlds, but each planet is unique in many respects. Planetary bodies also contain a record of the solar system’s history. The goals of this course include a better understanding of the processes that operate on distant worlds, gaining insight into how the Solar System has changed through time, and thinking about the future opportunties in planetary science. This class will not simply be a tour of the planets, nor will it attempt to answer all the questions normally dealt with in Astronomy and Cosmology courses. We will start from observations and use a judicious amount of mathematics, physics, and chemistry to achieve our goals. At semester’s end we hope you will have developed an understanding of the Solar System, a sense for the new and exciting discoveries in planetary science, as well as an appreciation of the important questions still to be answered.
