Presentation Transcript

  1. Tides

  2. The rise and fall of ocean water are called • tides

  3. What force pulls the moon and Earth toward each other? • gravity

  4. Why do tides occur? • The moon’s gravity pulls on part of the Earth as it revolves around the Earth.

  5. Circle the letter of each sentence that is true about tides. • a. The point on Earth that is closest to the moon has a high tide. • d. The point on Earth farthest from the moon has a high tide.

  6. What is a spring tide? • Sun Moon Earth • Gravity from the sun & moon pull together • Highest of High Tides

  7. What is a neap tide? • Sun Earth Moon • Gravity pulls away • Lowest of the Low tides

  8. When the moon is new or full, the gravitational forces of the sun and moon are pulling at the same side of the earth. (See the diagram below.) This occurrence creates the extra large "spring" tides. When the moon is at first and third quarter, the gravitational forces of the sun and moon are pulling at 90 degrees from each other. (see the diagram below.) This occurrence yeilds little net tides called neap tides.

  9. Circle the letter of each of the phases of the moon when a spring tide occurs. • a. new moon • c. full moon
