> || __terrestrial planet__- a planet that is primarily composed of silicate rocks and/ or metals. || || The terrestrial planets are mercury,venus,earth and mars. || > || __gas giant-__a large planet that is not primarily composed of rock or other solid matter. || || The gas giants are neptune, jupiter,saturn and uranus. || > || __planetesimal__-solid objects thought to exist in protoplanetary disks and in debris disks. || || planets form out of dust grains that collide and stick to form larger and larger bodies || > || __planet__- a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity || || The planets were thought by Ptolemy to orbit the Earth in [|deferent and epicycle] motions. || > || __satellite (moon__)- celestial planet that orbits a planet or smaller body, which is called its primary || || The largest natural satellites in the solar system are Earth's moon, Jupiter's Galilean moons, Saturn's moon Titan, and Neptune's captured moon Triton. || > || __asteroid__-a class of small Solar System bodies in orbit around the Sun. || || The large majority of known asteroids orbit in the main asteroid belt between the orbits of Mars and Jupiter. || > || __asteroid belt__-is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. || || An asteroid belts is mostly empty. || > || __meteor__-also known shooting stars are the streaka of light produced when a meteoroid burns up in the Earth's atmosphere. . || || Most meteors typically measure 1m across and 20km long, and consist of a cylinder of excited atoms and molecules. || > || __meteoroid__- is a sand- to boulder-sized particle of debris in the solar system. || || If a meteoroid reaches the ground and survives impact, then it is called a //**meteorite.**// || > || __meteorite__- is a natural object originating in outer space that survives impact with the Earth's surface. || || Most meteorites derive from small astronomical objects called meteoroids. || > || __comet__-is an icy small Solar System body that, when close enough to the Sun, displays a visible coma. || || Comet nuclei are themselves loose collections of ice, dust, and small rocky particles. || > || __nucleus__- is a membrane enclosed in organelle. || || A nucleus contains genetic material. || > || __coma__- a spherical cloud of material surrounding the head of a comet. || || This material is mostly gas that the Sun has caused to boil off the comet's icy nucleus || > || __kuiper belt__- a region of the Solar System beyond the planets extending from the orbit of Neptune to the Sun. || || Like the asteroid belt, it consists mainly of small bodies, or remnants from the Solar System's formation. || > || __oort cloud__- a hypothesized spherical cloud of comets which may lie roughly 50,000 AU, or nearly a light year, from the Sun. || || The outer extent of the Oort cloud defines the gravitational boundary of our Solar System. || 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.
 * ASSIGNMENT 3: Solar System Formation and Leftovers**
 * __nebula__- A diffuse mass of interstellar dust or gas or both, visible as luminous patches or areas of darkness depending on the way the mass absorbs or reflects incident radiation. || [[image:http://www.molwick.com/en/movement/r-nasa-jet-carina-nebula.jpg caption="external image r-nasa-jet-carina-nebula.jpg"]] || Nebula show us how stars are born and how they die, and they are generally made up of hydrogen and helium. ||
 * ASSIGNMENT 2: Rock Forming Minerals**

Granite: Granite rocks are igneous rocks which were formed by slowly cooling pockets of magma that were trapped beneath the earth's surface. Granite is used for long lasting monuments and for trim and decoration on buildings.


 * ASSIGNMENT 1: Earth Systems Interactions**

The Hydrosphere is made up of the oceans, seas, lakes, rivers, and glaciers. It also contains water in the ground and atmosphere. Exactly 3 percent of earth's water is fresh. Approximately 75 percent is in taken up by glaciers, and ice bergs. The Atmosphere is an invisible blanket of gases that surround our planet. The gases are important for respiration. The Atmosphere protects Earth's inhabitants from the harmful radiation. The Atmosphere helps maintain Earth's temperatures.The Hydrosphere and Atmosphere work together in the sense that the Atmosphere contains water, and water is what the Hydrosphere is made up of. Together they keep organisms alive as well as us humans.
