Tides
By: Audrey-Anne Girouard, Jessica Allard and Elizabeth Fiset

What are Tides?
How Tides are Caused
What are tides: Tides are big waves that move in the ocean.

What causes tides: It is caused by the interaction of the moon and the earth (gravitational forces). Even though the moon is much smaller than the earth, it is the one that ''pulls'' the most.

Who was the First Person to Explain Tides Scientifically?
Isaac Newton (1642-1727) was the first to explain tides scientifically. His explanation got published in 1886.

He was born in Woolstrophe, close to Grantham in Lincolnshire. In 1661, he attended Cambridge University and was a Lucasian Professor of Mathematics in 1669.

Spring and Neap Tides
Picture
During the spring tides, the high tides are very high and the low tides are very low. They occur when the earth, the sun, and the moon are in a line. They occur during the full moon and the new moon.
Neap tides are very weak tides. They occur when the sun and the moon are perpendicular to one another. Neap tides occur during quarter moons.

Calendar
High and Low Tides
High tides are when the water level is at it's maximum. If the moon is on top or on the opposite side of the planet, you will see a high tide.
Low tides are when the water level is at it's minimum. It all depends on the position of the moon.
