1. Bruce cambel discovered the first planet in an extra solar system. 2. october 6 1995 using the radial velocity method. 3. 51 pegasi b, 50 light years away 4. pluto is not considered a planet anymore


 * What is the radial velocity method?**
 * What were the 1st extrasolar planets like?**
 * 5 ?**

// Basalt is a Igneous Rock, Igneous Rocks are formed by cooling lava, but only when the lava is Viscus because // // when lava cools, it turns into different type of rocks depending on the way it has cooled, basalt cooled slow // // because also the fast lava cools, the SMALLER the crystals are going to be. //

//a. Describe the magnitude of this earthquake - It's a 6.3 so its really powerful// //b. Explain what "magnitude" means. (the scale used, and how a 3 on the scale differs from 2, 4, etc.)// //http:/http://en.wikipedia.org/wiki/File:NZ_faults_.pngen.http: //en.http://en.wikipedia.org/wiki/File:NZ_faults_.png.org/wiki/File:NZ_faults_.png://en.wikipedia.org/wiki/File:NZ_faults_.png.org/wiki/File:NZ_faults_.pngassigns a single number to quantify the amount of [|seismic energy] released by an [|earthquake]. It is a [|base-10] [|logarithmic scale] obtained by calculating the logarithm of the combined horizontal [|amplitude] (shaking amplitude) of the largest displacement from zero on a particular type of [|seismometer] (Wood–Anderson torsion). So, for example, an earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. || Theirs a boundary between two plates that met and caused shock waves. ||
 * **Impact** || Explain damage, cost, death toll, etc. damage was that many house, buildings and roads collapsed causing billions of dollars of damage .169 people died ||
 * **Cause** || Why did the quake happen where it did? Does this region get a lot of quakes? because of the plate boundaries moved causing this earthquake
