Explain why high & low tide are formed on seas.

Text Solution

Verified by Experts

The gravitational attraction of moon on sea water cause high tides. Tides at one place cause low tides at another. Attraction by sun also causes tides but only half of the magnitude. Hence on new moon and fall moon days. When both effects add, tides are very high.

Read the paragraph and answer the following question: You must be knowing about the high and low tides that occur regularly in the sea. The level of the sea water at any given location along sea shore increases and decreases twice a day at regular intervals. High and low tides occur at different times at places. The level of water in sea changes because of the gravitational force exerted by the moon. Water directly under the moon gets pulled towards the moon and the level of water there goes up causing high tide at that place. At two places on the earth at 90^(@) from the place of high tide, the level of water is minimum and low tides occur there. Where is high tide and low tide caused?
