This project is due on Monday 13 April 2015. It will count as a test grade [100 pts.] for 4 quarter. You will have 59 days to accomplish all of the tasks in the project. Late assignments will lose 10 pts. per day.
After 25 April this assignment may not be handed in. ALL The completed projects must be typed and printe d out. Handwritten copies will not be accepted.
[Keyboards are available in school and at the public library etc.] You should download an electronic copy of this assignment from classjump.com. As you answer the questions and complete the tasks, type the information right on the electronic copy that you downloaded and saved. You are encouraged to use the Internet as a resource. Please record the sites you used to get information.
Your Earth Science textbook and review book are also good sources of information [record these also if you use them]. There are many books and periodical which may be of help to you. Remember to “Save” your work as you progress. “My computer ate it”, is very sad to hear. Save often. 1] Vocabulary – define the following 26 terms: using “Google” Altitude: the angular distance of a heavenly body above the horizon. Asteroids: any of the thousands of small bodies of from 480 miles (775 km) to less than one mile (1.6 km) in diameter that revolve about the sun in orbits lying mostly between those of Mars and Jupiter. Astronomical Unit: a unit of lengh, roughly the distance from the Earth to the Sun. Azimuth: the angle between the north vector and the perpendicular projection of the star down onto the horizon. Big Bang: the rapid expansion of matter from a state of extremely high density and temperature that according to current cosmological theories marked the origin of the universe. Black hole: a region of space having a gravitational field so intense that no matter or radiation can escape. Blue shift:the displacement of the spectrum to shorter wavelengths in the light coming from distant celestial objects moving toward the observer.. Comets: a celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun.. Doppler Effect: an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.. Eclipses: an obscuring of the light from one celestial body by the passage of another between it and the observer or between it and its source of illumination.: "an eclipse of the sun". 1
Ecliptic: a great circle on the celestial sphere representing the sun's apparent path during the year, so called because lunar and solar eclipses can occur only when the moon crosses it.. Galaxy: a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.. Impact crater:a crater on a planet or moon caused by the impact of a meteorite or other object, typically circular with a raised rim.. Jovian planets: For centuries, people have looked to the sky and been fascinated with the vast bodies found in space. Our solar system consists of planets with a variety of characteristics. The chemical and physical properties of Mercury, Venus, and Mars are somewhat similar to Earth. Light Year: a unit of astronomical distance equivalent to the distance that light travels in one year, which
is 9.4607 × 10 km (nearly 6 trillion miles).. Main sequence:a particular order in which related events, movements, or things follow each other.: "the content of the program should follow a logical sequence". Meteors: a small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a streak of…
