1. Warm up The warm up is at your table You have 10 minutes from when the bell rings. You may use your vocabulary sheets and notes There should be no talking during warm ups

2. Earth’s Shape Oblate spheroid Caused by rotation around a minor axis

3. Moon Phases Phases always look the same Waxing=going toward a full moon Waning = going toward a new moon A new moon=the moon is between earth and the sun A full moon=the Earth is between the sun and moon Waxing=the right side of the moon is illuminated Waning= the left side of the moon is illuminated

4. tides

5. Tides Neap tides= a tide just after the first or third quarters of the moon when there is the least difference between high and low water. Spring tides= a tide just after a new or full moon, when there is the greatest difference between high and low water.

6. Tides How does a straight alignment between Earth, the sun, and the moon impact the tides on Earth? A. It produces the greatest change in high and low tides B. It produces the least change in high and low tides C. It produces semidiurnal tides. D. It produces diurnal tides. What position of the moon (M) will create the greater tidal range? (a) A and B (b) A and C (c) B and D (d) B and C

7. Stars Our star is 5 billion years old and has a life cycle of around 9 billion years Stars are the origin of all elements https://www.youtube.com/watch?v=FWwbMnXQ7bohttps://www.youtube.com/watch?v=FWwbMnXQ7bo first/third https://www.youtube.com/watch?v=tXV9mtY1AoIhttps://www.youtube.com/watch?v=tXV9mtY1AoI fourth

9. Fusion reactions in stars First reaction= hydrogen burning, 2 hydrogen fuse to make helium and energy (hydrogen burning) Helium burning is 2 nd fusion reaction carbon, oxygen, and nitrogen are created Carbon and oxygen burning is 3 rd fusion reaction- Ne, Na, Mg, Si, P, S, Cl, Ar are produced Silicon burning like is 4 th fusion reaction –this is the last reaction and produces iron. Iron most stable-at this point the star collapses into a white dwarf or has a supernova

10. Fusion vs fission? Draw a Double Bubble Map of Fusion and Fission fusion fission Differences Similarities Differences

11. Question How does the sun produce energy? A. Nuclear Fission B. Radioactive Decay C. Nuclear Fusion D. Ionic Bonding

12. Electromagnetic radiation Shorter wavelength= high energy, more dangerous, Longer wavelength=not dangerous, lower energy Energy produced by the sun= radiation Electromagnetic radiation filtered by atmosphere= all gamma, all x- rays, some UV and some infrared Not filtered= visible light, some UV and infrared, and some radio waves

13. Electromagnetic spectrum

14. Practice exam questions Sunscreen is used to protect skin from exposure to the Sun by blocking what kind of light? (a) gamma rays (b) x-rays (c) visible light (d) ultraviolet light 3. Which of the following choices best explains why grass on a distant hillside appears green? (a) grass reflects all colors except green (b) grass absorbs only green light (c) grass reflects green light and absorbs all other colors (d) grass transmits green light into other colors

15. Conduction vs convection vs radiation Create a 3 way venn diagram-use your vocabulary list Use the link on my website titled “venn diagram link” Create your diagram Save as a webpage Write down the link in your notebook or save the link in your googledocs in a word document-these are your notes

16. Question: ) The diagram below shows three different methods of heat transfer. (a) identify which letter in the diagram represents each of the following (i) Radiation (ii) Conduction (iii) Convection

17. Differential heating of Earth’s surface Water vs Land Water heats up more slowly and cools down more slowly than land

18. Earth’s magnetic field: Created in Earth’s core Protects Earth from the solar wind which would otherwise remove our ozone layer and leave us unprotected against electromagnetic rays Earth is like a dipole magnet (has two poles north and south) Van allen radiation belts are charged particles from the solar wind held in place by Earth’s magnetic field Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind and some particles sneak past it.magnetospheresolar wind https://www.youtube.com/watch?v=KAIyVZoXv9M

19. Earth’s magnetic field

20. closure How does heat from the sun get to Earth? A by radiation, using electromagnetic waves to transfer the heat B by convection, using liquids and gases to transfer the heat C by conduction, using solids to transfer the heat D by absorption, using primary waves to transfer the heat Which describes the difference between nuclear fission and nuclear fusion? A Nuclear fission is the process that produces the radiant energy of stars, and nuclear fusion splits a heavier nucleus into smaller nuclei. B Nuclear fission splits a heavier nucleus into smaller nuclei, and nuclear fusion is the process that produces the radiant energy of stars. C Nuclear fission produces the energy in the core of Earth, and nuclear fusion produces energy in nuclear power plants. D Nuclear fission produces energy in nuclear power plants, and nuclear fusion produces the energy in the core of Earth.
