 * Wiki Assignment 3: The Search for Habitable ("Earth-like") Planets**
 * Background:** Before the 1990's most scientists didn't think we would ever find planets outside of our own solar system, let alone potentially habitable "Earth-like" planets. Since then, some truly amazing discoveries have been made. This topic is truly cutting edge in Astronomy and all of science!


 * Directions:** Conduct some research on this topic and type a short summary on your wiki. I want to give you some creative freedom in terms of direction here, but at the bare minimum you should seek answers to the following questions:
 * 1) **NASA** were the first people to discover exoplanets.
 * 2) They found these exoplanets in 2011, They found them by a satellite they launched two years ago.
 * 3) We know that these planets are not that far away. One of the planets are 20 times closer than mercury. The diameter of one of these planets are 1.4 times bigger than earth so we no there bigger. some are these planets are thought to be habitable some aren't.
 * 4) 500 BC-1399 AD (greeks ponder other existing worlds)
 * 5) Based on what you have learned so far, **predict where you think this research will lead**? (i.e. what will scientists learn about extra-solar planets in the future or what is the next step in this area of study?) It would also be a good idea to mention some of the **problems, obstacles**, etc. that will need to be overcome.

Directions: Many of the minerals we learned about during chapter 4 are the chief "rock-forming minerals." Next, we are going to investigate the 3 major rock types: igneous, sedimentary and metamorphic. Your job during this assignment is to **search** the Internet for a common rock that is composed of __**2 or more of the minerals listed in bold below**__ and to **describe** how that rock forms from those minerals (1 good paragraph in your own words). You must include a **picture of the minerals** themselves, a **picture of the rock**, and a **picture illustrating the process by which the rock forms** (Include captions describing your images). The chief rock forming minerals are: **Calcite, Feldspar, Quartz, Augite, Garnet, Hornblende, Kaolin, Biotite Mica and Muscovite Mica.** Many many rocks are formed from these minerals so begin with some simple Internet research on "common rocks" formed from the most common minerals on our list. You can have one partner, but again make sure the completed assignment appears on both of your wikis. **And you may choose any chief rock other than granite (because that is my example below)**
 * Wiki Assignment 2: Rock Forming Minerals**

__**20 points total**__
 * Grading for assignment 4 is based on the following:**
 * 5 points for the 1 paragraph description of how the rock is formed (must briefly explain the process by which the rock is formed from it's component minerals. i.e. magma cooling, compaction, metamorphism; explain)**
 * 5 points for the picture, diagram, etc. showing how the process by which the rock forms**
 * 5** **points for the pictures of the individual minerals involved**
 * 5 points for the** **picture of the rock you're describing**


 * **Magnitude** || 6.3-magnitude is size; extent; dimensions, of an earth quake.On the Richter Scale, magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude of 5.3 might be computed for a moderate earthquake, and a strong earthquake might be rated as magnitude 6.3. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; as an estimate of energy, each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value. ||
 * **Impact** || 12 billion dollars in damage was caused by the earth quake, the death toll was 146. ||
 * **Cause** || Earthquakes are shakes and jiggles in the huge pieces of the Earth that form the outside of the big ball of our planet. Earthquakes occur regularly in New Zealand as the country forms part of the Pacific RIng of Fire, which is geologically active. About 14,000 earthquakes, most of them minor, are recorded each year.[|[] ||
