Important Facts:While Earth is rotating, bulges of water stay lined up with the moon.The Earth, Moon and Sun all have a gravitational pull that attract all of them to eachother.Tides make the sea level rise and fall regularly in most places.

Essential Question:How do the positions of Earth, Moon, and Sun cause tides?Answer:The gravitational pull of the sun, moon and earth all play a part in the making of tides. When all three bodies are in perfect alignment they create spring tides. When the moon and the sun are perpendicular to eachother they create neap tides. The sun is the furthest away from earth which makes it have less of an effect on Earth, but the mmon has a bigger effect on the tides than the sun because it is so close to Earth.

The Earth, Moon and Sun: Tides

Questions:During what moon phase or phases do neap tides occur?Which body has a bigger effect on the tides on Earth, The Moon or The sun?Spring tides occur when the ___, ___, and ____ are in perfect _____?

When the moon, Earth and Sun are in perfect alignment, they all have the combined force to create Spring Tides. Spring tides occur during the full moon and the new moon. Neap tides are the complete opposite. Neap tides are when the moon and the sun are perpendicular to eachother creating very low tides. Neap tides occur during quarter moons.

Description:The Earth revolves around the sun and the moon revolves around Earth. All three of the bodies have an effect whether it is small or big on the tides on Earth. When they are all in different positions, they create certain kinds of tides that are big and small. There are two main kinds of tides. They are Neap tides and Spring tides.

The tide generating force depends on the mass of an object and its distance. As the distance between the Earth and the moon or sun changes, the tidal force each produces will vary.

The sun, being the farthest away, has a very little effect on the tides on Earth. The moon has a much bigger effect on the Tides. Actually three times bigger than the Sun's effect.
