2.5 Back to number 1

This cycle can happen once or twice a day depending on the location of the area to the _________________. Tides that happen once a day are called _____________________. Tides that happen twice a day are called __________________________. Because the Earth rotates in the ______________ direction as the Moon, the cycle is actually slightly longer than a day at 24 hours and 50 minutes.

• ocean, diurnal tides, semidiurnal tides, same

• mountain, annual tides, quarterly tides, opposite

• river, nocturnal tides, tridiurnal tides, reverse

• desert, monthly tides, bimonthly tides, different

4. While the Sun and the _______________________ of the Earth both have some ________________ impact, the ________________________ of the ____________________ has the biggest affect on the tide. The ____________________ of the Moon causes a high tide both on the side of the Earth directly below the Moon (____________________ tide) and the opposite side of the Earth (__________________________). Low tides are on the sides of the Earth 90 degrees away from the Moon.
