high tide too? State with reasons.
(3) Explain the reasons for the generation
of waves.​

Answer 1

Answer:

(1) 7.25pm

(2) 107 degree

(3) wind, gravitational pull etc.

Explanation:

(1) There is high tide and low tide twice a day so if there is a high tide at 7 am, the timing of the next high tide and low tide on the same day is 7:25 pm evening

(2) The high and low tides are usually caused by the gravitational forces between the earth and the moon.

(3) Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. The gravitational pull of the sun and moon on the earth also causes waves.
