Unit5- Astronomy Vocabulary & Concept for 25 Index Cards In Bold 1. Explain the Earth's motion through space. 1. Explain the origin of Earth's motion based on the origin of the galaxy and its solar system. a. Explain how earth moves in the solar system. Earth/Env Sci i. Keywords: precession, barycenter, nutation, revolution, rotation, elliptical orbit 2. What is Earth's role in the hierarchy of organization within the Universe? a. Keywords: Galaxy, solar system, satellite, Universe, Big Bang Theory, Star 3. Explain how planets orbit a star using Kepler's laws. a. Identify and define Kepler's 3 laws of planetary motion(3 separate cards) i. Keywords: Kepler, ellipse, period, astronomical unit, perihelion, aphelion 4. Explain the relative motion of the Earth in the solar system, solar system in the galaxy, and galaxy in the Universe. a. Explain (Earth's tilt) how the tilt of the earth causes seasons on Earth (include keywords below in picture) i. Keywords: tilt, solar and lunar eclipse, seasons, Tropic of Cancer, Tropic of Capricorn, Arctic Circle, Antarctic Circle, Solstice, Equinox 5. Summarize that the Sun is not stationary. All objects in the solar system pull on the Sun. II. Explain how the Earth's rotation and revolution about the Sun affect its shape and is related to seasons and tides. 6. Describe daily changes due to the gravitational interaction between the Earth and Moon. a. Explain how the seasons change throughout the year b. Explain how the tides change throughout the day (diurnal, semidiurnal and mixed semidiurnal tides) i. Keywords: Tides, seasons, rotation, tilt, revolution, moon 7. (Earth circumference at poles and equator) Explain why the circumference around the equator is larger than that around the poles. III. Explain how the Sun produces energy which is transferred to the Earth by radiation. 8. Compare fusion and fission. a. Explain the processes of both reactions and how they produce energy. i. Keywords: fission, fusion, helium, hydrogen, nucleus, atom, star 9. Identify the forms of energy produced by the Sun and how some are filtered by the atmosphere. a. Identify and draw the forms of energy on the electromagnetic spectrum in order. i. Keywords: electromagnetic radiation (radio waves, X-rays, etc...) 10. Summarize how energy flows from the sun to the Earth through space. IV. Explain how incoming solar energy makes life possible on Earth. Explain how the tilt of the Earth's axis results in seasons due to the amount of solar energy impacting Earth's surface. Keywords: tilt, solar radiation 11. Explain differential heating of the earth's surface. a. Explain why land heats faster than water (include keywords and specific examples) i. Keywords: heating, specific heat 12. Explain how solar energy is transformed into chemical energy. a. Explain why solar energy is essential to plants and food webs. i._Keywords: photosynthesis (definition and diagram) b. Explain how earth's magnetosphere field protects the planet. Describe how the magnetic field deflects solar radiation.
