1 Earth in the Universe Topic 3 Remember to wait for the vocabulary word to pop up at the end! Can you guess it before it comes up? Created by P. Bordas MS, CCC-SLP

2 Origin and Age of the Universe

3 Celestial Object Any object outside or above Earth’s atmosphere http://news.globaltv.com/1976920.bin?size=sw620nws

4 Universe Everything that exists in any place – all the space, matter, and energy in existence http://www.sydneyobservatory.com.au/blog/wp-content/uploads/2007/06/milky-way-map_atlas-of-the-universe.jpg

5 Big Bang Theory States that all matter and energy started out concentrated in a small area and, after a gigantic explosion, matter began to organize into subatomic particles and atoms. http://en.beta.rian.ru/images/15660/40/156604039.jpg ?

6 Doppler Effect The shifting of wavelengths http://dragonphysics.pbworks.com/f/1234547786/gene%20waves_doppler.gif

7 Blue Shift This results when the Earth and another celestial object are coming closer together and the electromagnetic waves are bunched together http://images2.cafepress.com/product/331573172v2_225x225_Front.jpg

8 Red Shift This results when the Earth and another celestial object are moving apart and the electromagnetic waves are spread out http://images3.cafepress.com/product/331573403v2_225x225_Front.jpg

9 Structure of the Universe

10 Galaxy A collection of billions of stars and various amounts of gas and dust held together by gravity http://www.propermotion.com/jwreed/Photography/Andromeda%20Galaxy.jpg

11 Milky Way Galaxy Our solar system is a part of this spiral- shaped galaxy http://www.sciencenewsforkids.org/articles/20050202/a667_6174.jpg

12 Star Usually a large ball of gas held together by gravity that produces tremendous amounts of energy and shines http://images.astronet.ru/pubd/2006/06/20/0001214544/leoregulus_croman.jpg

13 Nuclear Fusion Combining of the nuclei of smaller elements to form the nuclei of larger elements with some of the mass being converted into energy http://www.lancs.ac.uk/ug/hussainw/fusion.jpg

14 Luminosity Measures how bright a star would be in relation to the sun if all stars were the same distance from an observer http://www.daviddarling.info/images/luminosity_class.jpg

15 Solar System

16 The sun and all objects that orbit the sun under its gravitational influence http://horoscopicastrologyblog.com/wp-content/uploads/2008/11/solar-system.jpg

17 Asteroid A solid rocky and/or metallic body that independently orbits the sun http://www.spacedaily.com/images/asteroid-617-patroclus-binary-jupiter-orbit-desk-1024.jpg

18 Moon Body that orbits a planet or asteroid as those objects orbit the sun http://scienceblogs.com/startswithabang/upload/2009/08/paper_folding_to_the_moon/moon_2_bg_0722021.jpg

19 Comet Mainly composed of solids that easily change to gases when heated Largely ices of substances such as water and methane mixed with rocky or metallic solids http://www.astro.cornell.edu/academics/courses/astro2201/images/comet_west.gif

20 Meteor Very small solid fragments that orbit the sun http://msnbcmedia1.msn.com/j/msnbc/Components/Photos/041112/041112_leonid_meteor_vmed.widec.jpg

21 Impact crater A depression in the Earth’s crust created by a meteorite that has sufficient mass http://www.lpi.usra.edu/science/kiefer/Education/SSRG2-Craters/meteor_crater.gif

22 Impact Event Even after Earth and other planets formed, their gravitational forces pulled on the smaller clumps of matter to cause comets, asteroids and meteoroids to collide with planets in what is called….

23 Planet Characteristics

24 Terrestrial Planets Close to the sun and mostly solid Relatively small diameters and high densities Rocky surfaces are dotted with impact craters Have few or no moons and have no rings Planets similar to Earth including: Mercury, Venus, Earth and Mars http://www.eso.org/public/outreach/eduoff/vt-2004/Background/Infol2/vt2004-if8-fig3.jpg

25 Jovian Planets Far from the sun Relatively large diameters and low density No solid surfaces and no craters Have many moons and rings Are planets similar to Jupiter including: Jupiter, Saturn, Uranus and Neptune http://startswithabang.com/wp-content/uploads/2008/10/outer_planets_small_2.jpg

26 Rotation Planets spin with this motion on an imaginary axis, amount of time it takes for a planet to spin one time around its imaginary axis determines the length of its day http://www.physicalgeography.net/fundamentals/images/earth_rotation.jpg

27 Revolution A planet’s movement around the sun in a path called an orbit https://hhe.wikispaces.com/file/view/Picture_44.png/63661306/Picture_44.png

28 Ellipse Oval shaped orbit made by the Earth http://www.astronomyforbeginners.com/images/diagrams/ellipse_orbit.gif

29 Foci, Focus Fixed points within the ellipse http://upload.wikimedia.org/wikipedia/commons/c/c9/Kepler1.gif

30 Eccentricity The degree of flattening or “ovalness” of an ellipse is measured by this http://cxc.harvard.edu/csc/why/imgs/JD_err_ellipses.jpg

31 Inertia The concept that an object at rest will tend to remain at rest, and that an object in motion will maintain the direction and speed of that motion unless an opposing force affects it http://www.asc-csa.gc.ca/images/spacesuit_inertia.jpg

32 Gravitation Attractive forces that exist between any two objects in the universe http://psychogeeks.com/wp-content/uploads/2007/04/gravity.gif
