 * 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]] || Nebula show us how stars are born and how they die, and they are generally made up of hydrogen and helium. ||
 * __terrestrial planet__- a planet that is primarily composed of silicate rocks and/ or metals. || [[image:http://www.astro.ljmu.ac.uk/courses/phys134/pic/solsys/terrestrial.jpg]] || 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. || [[image:http://www.astrophys-assist.com/educate/robot/images/gas-giants.jpg]] || The gas giants are neptune, jupiter,saturn and uranus. ||
 * __planetesimal__-solid objects thought to exist in protoplanetary disks and in debris disks. || [[image:http://www.spacedaily.com/images/planetesimal-belt-bg.jpg]] || 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 || [[image:http://cache2.allpostersimages.com/p/LRG/7/767/SSSZ000Z/posters/planet-earth.jpg]] || 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 || [[image:http://cdn.wn.com/pd/96/5d/adc263f07093c775dd810e87fca3_grande.jpg]] || 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. || [[image:http://www.thenoseonyourface.com/wp-content/uploads/2007/02/asteroid.jpg]] || 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. || [[image:http://upload.wikimedia.org/wikibooks/en/1/18/Asteroid_belt_between_Mars_%26_Jupiter.PNG]] || 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. . || [[image:http://3.bp.blogspot.com/_0gGXyf2m4kg/SlYrz6Xr04I/AAAAAAAAAf0/u1K0DP-u7iU/s400/shooting-stars.jpg]] || 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. || [[image:http://www.farfuture.com/fig/crash.jpg]] || 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. || [[image:http://xenophilius.files.wordpress.com/2008/10/meteorite.jpg]] || 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. || [[image:http://71.18.228.62/images/Comet-Animation-3.gif]] || Comet nuclei are themselves loose collections of ice, dust, and small rocky particles. ||
 * __nucleus__- is a membrane enclosed in organelle. || [[image:http://ridge.icu.ac.jp/gen-ed/cell-lect-gifs/09nucleus-diag.GIF]] || A nucleus contains genetic material. ||
 * __coma__- a spherical cloud of material surrounding the head of a comet. || [[image:http://apod.nasa.gov/apod/image/0705/comacluster_spitzer_0.jpg width="800" height="694"]] || 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. || [[image:http://www.rense.com/general86/image0032.jpg]] || 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. || [[image:http://www.dailygalaxy.com/photos/uncategorized/2008/08/18/bigoort_2.jpeg]] || The outer extent of the Oort cloud defines the gravitational boundary of our Solar System. ||

The minerals that are found in granite are **[|quartz],** **[|feldspars]** and **micas**. **Quartz's** hardness, lack of chemical reactivity and near lack of cleavage give granite a significant amount of its desirable durable properties. The K-feldspars are generally the ones that give granite its color variations from yellow to orange to pink or blue. Dark K-feldspars can give granite its black varieties as well.. The ** micas ** are generally silver, black or brown or violet or pink and provide the sparkle that some granites possess.

Directions: Work with a partner to explain one example of an **interaction between 2** of the [|earth systems] we discussed in class. (Lithosphere, Hydrosphere, Atmosphere, Biosphere). The systems are described in your notes for unit 1. Your job is to **type one paragraph** explaining ** how they interact ** and to ** include at least 1 supporting image **. Don't forget to make sure that the completed assignment is copied onto both of your wikis for grading purposes along with the title: **ASSIGNMENT 1: Earth Systems Interactions**.
 * ASSIGNMENT 1: Earth Systems Interactions**

Assignment:

The **biosphere** is the global sum of all ecosystems. It can also be called the zone of life on Earth. The biosphere includes all living organisms on earth, together with the dead organic matter produced by them. The biosphere interacts with the elements of the [|lithosphere], [|hydrosphere] and [|atmosphere]. A in [|physical geography] describes the combined mass of water found on, under, and over the surface of a [|planet]. Approximately 71% of the [|Earth]'s [|surface] is covered by [|ocean]**.**
