“When the wind touches the surface of the sea, it causes ripples. When the wind continues to push the ripples forward, and gravity pulls them down, they turn into waves and swells. And the waves keep moving for miles and miles in an ocean until they find a shore and break against it.

When a wave reaches shallow water, its bottom hits the ground and slows down. But its top keeps going on at the same speed and topples over at the shore. That’s what makes the frothy breaker.

A wave can travel for many days and for thousands of miles, but the sea always stays in one place. That’s simple! If two people hold a rope at the two ends and one of them gives it a sudden push, you can make waves, but the rope remains in the same place, doesn’t it?”


“Twice a day, sea water rises slowly and covers part of land, then falls back. High tide is when the water covers the most land. Low tide is when it covers the least amount of land.

The earth’s gravity keeps the water of the oceans stuck to the earth. And the moon’s weaker gravity pulls the water towards it as it passes over the oceans. When the moon passes over land, a bulge of water follows it until the moon goes too far over land and its gravity becomes too weak. That’s high tide and low tide for you!

Oh, and by the way, the piece of land between high tide and low tide is called the inter-tidal zone. That’s my area, see, and you are trespassing! So get out from my turf! It’s my busy time and I have to work, now. I’m not on a holiday, unlike you!”
