Across
- 1. A phase of the moon coming after a new moon and before a 1st quarter moon that is a lit up crescent on the right
- 5. A phase of the moon that comes after a 1st quarter moon and before a full moon where almost all of the moon is lit up from the right to the left, except a small bit on the left.
- 12. transverse waves consisting of changing electric fields and changing magnetic fields
- 13. The point on the celestial sphere where the sun is farthest south; also, the time of year when the sun passes this point, about December 22, and winter begins in the Northern Hemisphere.
- 15. The transfer of thermal energy by the circulation or movement of a liquid or gas
- 20. Caused by the tilt of Earth on its axis as it revolves around the Sun
- 21. the blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon
- 27. transfer conduction, convection, radiation
- 28. When the moon, Earth, and Sun are all in a straight line. It creates the biggest tidal range on Earth in a 24 hour period.
- 29. In which eclipse do we see a small ring-like sliver of light from the sun. This is due to the moon being at its further point from the sun and in the antumbra.
- 30. The direct transfer of heat from one substance to another substance that it is touching.
- 31. A measure of the average energy of motion of the particles of a substance.
- 32. comes from changes to the atom's nucleus: when the nucleus of an atom divides
Down
- 2. the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length (about September 22 and March 20).
- 3. Occurs when the Moon passes directly between the Sun and Earth and casts a shadow over part of Earth
- 4. When the moon and Earth are perpendicular (create a right angle) with the Sun. It creates the smallest tidal range on Earth in a 24 hour period.
- 6. The moon is a quarter of the way around the Earth. You can see the right half of the moon.
- 7. A phase of the moon that comes after a full moon and before a last quarter moon where all of the moon is lit up except for a small bit on the right side of the moon that we can see.
- 8. conduction, convection, radiation
- 9. the region around a magnet where the magnetic force is exerted
- 10. The spinning motion of a planet on its axis
- 11. the range of wavelengths or frequencies over which electromagnetic radiation extends.
- 14. the periodic rise and fall of the water level in the oceans and other large bodies of water
- 16. causes Earth's seasons. (23.5 degrees)
- 17. a kind of radiation including visible light, radio waves,gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously
- 18. Particles such as electrons, protons, and atomic nuclei that zip through interstellar space at close to the speed of light.
- 19. moon phase when the entire side facing Earth is illuminated.
- 22. The process by which two or more small nuclei fuse to make a bigger nucleus
- 23. The point on the ecliptic where the Sun is farthest north of the celestial equator. It is also used to refer to the date on which the Sun passes through this point. (about June 21st)
- 24. Phase when the cresent light is on the left; occurs before a new moon
- 25. that is radiated or transmitted in the form of rays or waves or particles
- 26. The movement of an object around another object
