 * Include a definition or link to these 16 terms**: nucleus, coma__, Kuiper belt, Oort cloud__.
 * 1) Nebula - Interstellar cloud of dust and gas. Gravity begins the process of star creation, bringing together materials into these clouds, eventually condensing. [[image:http://whs86.wordpress.com/files/2007/08/crabb.jpg]]
 * 2) Planetesimal - Small bodies of matter formed in the early stages of the Solar System. They were the first large, solid bodies to form in the Solar System.
 * 3) Gas giant - Planet consisting mainly of gases, often having no solid surfaces. These form at the same time period as terrestrial planets, but form much further from the sun. They are much larger.
 * 4) Terrestrial planet - Planet consisting mainly of compact rock. These formed as planetesimals collided, forming close to the sun.[[image:http://www.our-earth.net/images/Early-Solar-System.jpg]]
 * 5) Satellite - Any smaller body orbiting a larger body. Many satellites, or moons, formed around planets like Jupiter from planetesimals and other debris.
 * 6) Asteroids - Small rocky bodies orbiting the sun, sized from 1-1000 kilometers. They are left over from the formation of the Solar System. [[image:http://www.ionline.pt/adjuntos/102/imagenes/000/160/0000160526.jpg]]
 * 7) Asteroid Belt - Ring of higher concentration of asteroids, found between Mars and Jupiter. These are left because they are far enough from most planets that their orbit goes largely unaffected.
 * 8) Meteoroid - Asteroid fragment that falls towards earth and enters its atmosphere. These occur because of Earth's gravitational pull on other close objects.
 * 9) Meteor - The streak of light produced when a meteoroid burns in Earth's atmosphere. The high friction of Earth's atmosphere burns and melts the asteroid upon entry, leaving the streak. [[image:http://www.thedailyinquirer.net/wp-content/uploads/2009/11/leonid-meteor-shower-november-2009.jpg]]
 * 10) Meteorite - Any part of a meteoroid that does not burn up, and lands on Earth. Large Meteoroids will not completely burn up, eventually making contact with earth.
 * 11) Comets - Icy bodies that have highly eccentric orbits around the sun. These are remnants of Solar System formation.

Limestone is a sedimentary rock composed largely of calcium carbonate, mainly in the form of calcite. It's formed in shallow marine waters. It forms as an organic sedimentary rock, from materials such as shell and coral. The warm marine waters of the Bahamas are the perfect environment for many of the shelled animals that contribute, so those areas are full of limestone. Limestone also forms through evaporation, such as in the case of stalagmites and stalactites. When water drips off of a stalactite for example, if it evaporates, the minerals will be crystallized into the stalactite.

Atmosphere and Biosphere: As a plant grows throughout it's life cycle, it will continue to consume CO2 and release O2 during photosynthesis. This builds energy within the plant. A plant has to consume that energy as well, and does so during respiration. Similar to animals, their respiration will consume O2 from the atmosphere and release minimal amounts of CO2. When the plant eventually dies, fungi will decompose it. This may release gases such as CO2 and CH4 (methane) while it decomposes. Future plants that are created will need those gases, and will complete the cycle, and start it all over again.
