In and Out Have you ever wondered what would happen if we didn t have the sea? Well, the world would dry up. With no water we can t live.

A Tsunami and a Hurricane The ocean can cause destruction. Waves can create a big deluge and crash into cities. But what is the cause of this? Tsunamis can create great devastation. When an earthquake happens under the ocean, it makes a big wave called a tsunami. If the wave is close to shore it will cause a flood, destroying cities and sometimes people die. Hurricanes are also a cause of damage from the ocean. Hurricanes are violent storms. They can push the water making big waves. These waves can cause floods. Floods can make it hard for people to survive if the people don t have food or shelter. Wavy facts Did you know that floods can kill thousands of people? 2 A big wave making a flood.
The Moon and the Tide What is a tide? Tides are the rise and fall of the ocean. Tides are caused by the gravitational pull of the sun and moon and the rotation of the earth. Tides have cycles. The cycles are caused by the moon rotating the earth and the position of the sun changing. The ocean is always rising and falling. The cycles are: 1) the sea levels rises 2) high tide 3)sea level falls 4)low tide 5) repeats. Wavy facts did you know that if we did not have gravity then we would fly out into space swirling around? The location of the moon affects the tide the most. The gravity (or pull) of the moon causes a high tide on the side of the earth closest to it and on the opposite side. Low tides are on the sides of the earth ninety degrees from the moon. 3 Picture showing high and low tide. The moon and a wave. A moon making a wave.
Amazing ocean Animals How do fish live in the ocean? Some fish eat plants that grow in the water. Bigger fish eat those fish. Then bigger fish eat those fish.

Most live at the top in the sunlit zone, such as minnows, krill, sharks, whales, dolphins, etc. Other fish, like the giant squid, live in the twilight zone where there is little light.
