Why don’t we have eclipses every month? The moon’s orbit has a tilt to it compared to the orbit of the Earth around the sun. This causes the moon to pass above or below the Earth.

Notes on Tides … again. 

Tides Information! Tides are the rise and fall of water at a coastline. High Tide- Water comes in Low Tide – Water goes out Occurs in all bodies of water but is the most noticeable with the ocean.

Causes of tides Tides are caused by the interaction of the Earth, Moon and Sun. Gravity “pulls” on the water causing a tidal bulge. There are two types of tides High Tide Low Tide

High Tides Occurs on 2 sides of the Earth The side of the Earth that is closest to the moon. The side of the Earth that is farthest away from the moon.

Low Tide Occurs on two sides of the Earth The sides of the Earth that are between the high tide

Tide Cycles! Daily Tide Cycle Monthly Tide Cycle There are two high tides everyday There are two low tides everyday Monthly Tide Cycle There are two special tides that occur when the sun, moon, and Earth line up in specific ways Spring Tides Neap Tides

Spring Tides The Moon, sun, and Earth are in a straight line. High tides are higher than normal, low tides are lower than normal. These happen during new moons or full moons.

Neap Tides The Moon, Sun and Earth are at a 90 degree angle. High tides are lower than normal and low tides are higher than normal. Neap tides occur during quarter moons.
