They are responsible for the rise and fall in sea level.. Tides . May 2013. What is a TIDE?. Rise and fall in ocean levels. Most observable at the coastlines. What is a TIDE?. 2 High tides and 2 Low tides occur daily. Approx. 6 1/2 hours apart. What causes TIDES?. Tides. Tides are the daily changes in the elevation of the ocean surface. Tides are the daily rise and fall of the Earth’s waters on its coastlines.. Tides are caused by the interaction of the Earth, the moon and the sun.. Description of Waves. A wave is the rhythmic movement that carries energy through space or . matter. Waves are generated by wind flowing over the water . surface. As a wave passes, water moves up and down in a circular pattern – returning to its original position. 1. Water on Mars (. SciShow. ). https://www.youtube.com/watch?v=djcszDBsQkE.

Everywhere around the world there are seasons and tides. But have you ever asked why they happen? Come with me, Ms. Frizzle, on the Magic School Bus and we can find out! Everyone on board? Okay then, time to go to space!. their highest point of the day and fall to their lowest point . every 12.5 hours. . The tides result from the rotation of Earth on its axis as gravity . from the moon and the sun pull on Earth and its water. Think . What celestial object is attracted to the Earth?. The Moon. What celestial object is the Earth attracted to?. The Sun. Effect of the moon on the Earth. The Moon’s gravity also pulls on the Earth, but because the Earth is solid, it doesn’t seem to respond.. TidesThe tides are the rising and falling of the ocean surface as a result of the gravitational pullof the moon and the Sunon the earthThe Moon plays a bigger role than the Sun because it is closerEff
