Question

What does the rising and falling of the tide signify ? What do we have to do to survive ?​

Answer 1

The Tides. ... The tides--the daily rise and fall of the sea's edge--are caused by the gravitational forces between the earth, the moon and the sun. Since the moon is closer to our planet than the sun, it exerts a stronger gravitational pull on us. (The sun only has 46% of the tide-generating force of the moon.)

Answer 2

they signify the gravitational force of moon and sun on our sea and ocean
