Across
  1. 4. An astronomical event that occurs when one celestial body moves into the shadow of another, or passes between a third body and the observer, temporarily blocking the light.
  2. 6. Tide A tide with the least difference between consecutive high and low tides. This occurs twice a month when the Sun and Moon are at right angles to each other relative to Earth.
  3. 7. Tide An exceptionally high tide with the greatest difference between consecutive high and low tides. This occurs twice a month during the full moon and new moon phases when the Sun, Moon, and Earth line up in a straight line.
  4. 11. The spinning of a celestial body (like Earth) around its own internal axis. One full rotation of Earth equals one day.
  5. 12. Either of the two times each year (around June 21 and December 21) when the Sun reaches its highest or lowest point in the sky at noon, resulting in the longest and shortest days of the year.
  6. 13. The periodic rise and fall of sea levels across Earth's oceans, primarily caused by the combined gravitational forces exerted by the Moon and the Sun.
  7. 14. The scientific study of celestial objects, space, and the physical universe as a whole.
Down
  1. 1. The dark, inner, cone-shaped part of a shadow cast by a celestial body where all light from the light source is completely blocked.
  2. 2. An eclipse that occurs when the Moon passes directly between the Sun and Earth, casting a shadow on Earth and blocking all or part of the Sun's light.
  3. 3. An eclipse that occurs when Earth passes directly between the Sun and the Moon, causing Earth's shadow to fall upon the Moon.
  4. 5. The lighter, outer part of a shadow surrounding the umbra where the light from the source is only partially blocked.
  5. 8. The universal force of attraction acting between all matter, responsible for keeping planets in orbit and causing tides on Earth.
  6. 9. The orbital movement of one celestial body around another (such as Earth orbiting the Sun or the Moon orbiting Earth).
  7. 10. Either of the two times each year (around March 21 and September 23) when the Sun crosses the celestial equator, resulting in a day and night of approximately equal length all over the earth.
