Question

ocean waves and tides
lesson 2
directions: unscramble and write the words. then write each term on the line before its definition.

1. nusattim
2. lsevlaee
3. niepeatd
4. dite
5. rtigdalnea
6. ridestingp
7. the periodic rise and fall of the oceans surface caused by the gravitational force between earth and the moon and between earth and the sun
8. occurs when earth, the moon, and the sun form a right - angle; has the lowest tidal range
9. the average level of the oceans surface at any given time
10. a wave that forms when an ocean disturbance suddenly moves a large volume of water
11. occurs when earth, the moon, and the sun form a straight line; has the largest tidal range
12. the difference in water level between a high tide and a low tide

Explanation:

1. Unscramble the words to match with the definitions. "nusattim" is "Summit" which doesn't seem relevant here, likely a mis - clue. "lsevlaee" unscrambles to "Sea level" which is the average level of the ocean's surface at any given time. "niepeatd" unscrambles to "Tide" which is the periodic rise and fall of the ocean's surface caused by gravitational forces. "dite" is "Tide". "rtigdalnea" is "Tidal range" which is the difference in water level between a high tide and a low tide. "ridestingp" is "Spring tide" which occurs when Earth, the Moon, and the Sun form a straight - line and has the largest tidal range.
2. Match the unscrambled words with the definitions:

• 7. Tide
• 8. Neap tide (not in the scrambled words but for knowledge: when Earth, Moon and Sun form a right - angle and has the lowest tidal range)
• 9. Sea level
• 10. Tsunami (not in the scrambled words but for knowledge: a wave formed by ocean disturbance moving a large volume of water)
• 11. Spring tide
• 12. Tidal range

Answer:

1. Tide
2. Neap tide
3. Sea level
4. Tsunami
5. Spring tide
6. Tidal range
