Seasons & Tides

2. A stretched-out circle, like the shape of Earth’s path around the Sun.
5. Imaginary line around the middle of Earth, dividing it into the top (Northern) and bottom (Southern) halves. It’s the hottest part because it gets the most sunlight.
8. Season with short days and less sunlight because Earth tilts away from the Sun.
10. Really high and really low tides that happen when the Sun, Moon, and Earth line up.
12. Swelling of ocean water caused by the pull of gravity from the Moon and Sun, making high tides.
15. When the ocean water is at its lowest level on the shore.
17. When one thing moves around another, like Earth going around the Sun.
19. When the ocean water is at its highest level on the shore.
20. When something spins in place, like Earth turning in one day.

1. Invisible line that something spins around, like Earth spins on its axis through the North and South Poles.
3. Season with long days and lots of sunlight because Earth tilts toward the Sun.
4. A time when the difference between high and low tides is smaller, happening when the Sun and Moon are at a right angle to Earth.
6. Rise and fall of ocean water caused by the Moon’s and Sun’s gravity.
7. The slant of something’s axis, like Earth being tilted at 23.5°.
9. Difference between the highest and lowest water levels.
11. When two lines or things meet at a right angle, like the corner of a square.
13. The path one thing takes as it moves around another, like the Moon moving around Earth.
14. Force that pulls things toward each other, like keeping us on Earth or making things fall.
16. When something stays still or keeps moving the same way unless something makes it change.
18. Half of Earth, either the top (Northern) or bottom (Southern).
