TIDES

TIDES. Are periodic rise and fall of all ocean waters caused by the gravitational attraction of the moon and the sun upon the water and upon the earth itself. Spring Tide. Occurs during the full moon and the new moon. And also when the sun, moon, and the earth align.

  1. TIDES Are periodic rise and fall of all ocean waters caused by the gravitational attraction of the moon and the sun upon the water and upon the earth itself.

  2. Spring Tide Occurs during the full moon and the new moon. And also when the sun, moon, and the earth align.

  3. When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times,the high tides are very high and the low tides are very low. This is known as a spring high tide.

  4. Neap Tide • It occurs when the moon is in the first or third quarter and it is at right angles to the sun relative to the earth.

  5. During the moon's quarterphases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide.

  6. What Does the Pull of the Moon Do to the Oceans?The gravitational pull of the moon creates two types of tides: high and low. A tidal bulge occurs in the oceans on the side of the earth nearest the moon; a second tidal bulge occurs on the far side of the earth. These bulges are high tides. The areas between the tidal bulges experience low tide. Usually two high and two low tides occur each 24 hours and 50 minutes.
