Tides


 * __~ Tides ~__**

** Welcome to Shay and Nickalei's Water system's tides wiki ** media type="custom" key="9649168" Tides are the rise and fall of sea levels caused by multiple factors:
 * one of them is the gravity
 * another is the pressure put out and by the Moon and the sun
 * the last one is the spin of the Earth.

This is when the tides are highest and lowest do to solar or lunar positions around the earth

There are two types of tides These are relative to the time of the day these times are when gravity shifts due to the solar and lunar positions the tide is the highest when it is closest to the moon and sun the tide is lowest when it is away from the sun and moon
 * High tides
 * And low tides

__The moon affects the gravity around the water but the moon also has an interesting effect on the human body.__

**this is an example of drastically high tides**

**Questions** (textbook questions pages 245 - 247)

**Q1.** What is a tidal range?
 * A1. The difference between the water levels at high tide and low tide is called tidal range **

**Q2.** How is a tidal bulge formed? What are two things to cause them?
 * A2. Tidal bulges form when the moon pulls on tides with its gravitational pull and make the water to bulge out causing a tidal bulge. The sun and the moon cause tidal bulges. **

**Q3.** How many high tides and low tides would an area experience in one day? Explain **over the 2 cycles which causes the gravity to pull on the ocean resulting in high tides**
 * A3. Two, because the moon circles around the world twice and the moon has an affect on the gravity **

**Q4.** Explain how the sun and moon work together to make neap and spring tides?
 * A4. They work together because they shift the gravity around the earth to cause a pressure change on the oceans. **

**Q5.** How often to spring and neap tides occur?
 * A5. When the sun and moon are pulling at right angles, the tidal range produces neap tides. When the sun, moon and earth are all alinged, the tidal range produces spring tides. **

**Q6.** What are two things that affect the tidal range of an area? **A6. Latitude and the cycle consistancy (new to full moon).**

**Q7.** Why does an area like the Bay of Fundy in the Maritimes get such a large tidal range? [] [] [|http://home.hiwaay.net/~krcool/Astro/moon/moontides/]
 * A7. Due to the topography and the narrow passage as well as the northern latitude **
