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? The Moons gravity pulls up on the oceans because they are not attached to the Earth. The Suns gravity also pulls up on the oceans.
Spring Tides Occur during New and Full moons Earth, Moon, and Sun align Gravity from the Sun and Moon PULL on the oceans in the SAME direction Big difference between High and Low tides
Neap Tides Occur during Quarter moons (Half moons) Earth, Moon, and Sun form a right angle Gravity of Moon and Sun PULL in DIFFERENT directions Little difference between High and Low tides
Tidal Range Difference between High Tide and Low Tide in an area High Tide – Low Tide = Tidal Range Changes with positions of the Moon and Sun
Bay of Fundy, Nova Scotia, CA Bay of Fundy from space Tide variation at Bay of Fundy
TIDES Are periodic rise and fall of all ocean waters caused by the gravitational attraction of the moon and the sun upon the water and upon the earth itself.
Chapter 11 S3 Tides. Ch 11 S3 Essential Questions 1. What causes tides? 2. What affects the heights of tides? 3. How are tides a source of energy?
If the moon had the mass of a golf ball, the sun would have the mass of about 110 school buses! Although the moon is much smaller than the sun is, the.
Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational pull of the moon and inertia. Most coastal areas see.
DO NOW QUESTION When Hurricane Sandy hit NJ and NY in October of 2012, severe flooding occurred in coastal areas. Due to the moon’s location in its orbit,
Daily Changes in Tides. Tides- Caused by gravity from the Sun and the Moon pulling on and deforming large bodies of water Historical Tide Gauge at Anchorage,
I.Definition: the periodic rise and fall of sea level within a day a. tides are measured relative to points on land b. highest level = high tide c.
Tides. What are they: Tides are daily changes in level of ocean surface. Discovered by Sir Isaac Newton. Causes: Gravitational pull of the moon and sun.
Gravity and Tides. How does the relative position of the Sun, Earth, and Moon causes tides on Earth? How do the times of high and low tide along the Atlantic.
Why are there ocean tides?. Every 6 hours there is either a low tide or a high tide. 2 of each per day.
What are tides? The daily rise and fall of Earth’s waters at its coastline.
