Slide 2

Although the Sun, our moon and the Earth itself are revolving around each other we are usually not revolving in the same plane (all lined up) But occasionally we do line up in a straight line. When this happens, an eclipse occurs

Slide 3

When the shadow of one celestial body falls on another an eclipse occurs. A solar eclipse happens when the moon is between the Earth and the sun Solar= EMS A lunar eclipse happens when the Earth comes between the moon and sun. Lunar = MES https://www.youtube.com/w atch?v=rVE8PFYlwSM https://www.youtube.com/w atch?v=rVE8PFYlwSM

Slide 4

Can only occur during the new moon phase The moon passes directly between the Sun and Earth, blocking the light from the Sun The shadow of the Moon falls on a small portion of Earths surface and very few people are able to see it.

Slide 6

Can be seen by anyone on the night-time side of the Earth where the Moons not hidden by clouds. A total eclipse of the moon can only happen when the moon is full, because that's when the moon is exactly opposite from the sun in the sky. The moon is full about once a month, but eclipses happen less often because sometimes the moon is too high or too low for the Earth's shadow to fall on it..

Slide 7

.. Usually lunar eclipses (eclipses of the moon) happen two to four times a year. Sometimes they are full eclipses, and sometimes only part of the moon is eclipsed. When there's an eclipse of the moon, anyone on the night side of Earth can see it.

Slide 9

During a lunar eclipse, youll see the Earths shadow creeping across the moons face. The shadow will appear dark, like a bite taken out of a cookie, until the shadow completely covers the moon. Then, during the breathtaking moments of totality, the shadow on the moons face often suddenly changes. Instead of dark, it appears red. Why?

Slide 10

The reason stems from the very air we breathe. If the Earth had no air, then Earths shadow on the moon during a lunar eclipse would appear black. The presence of Earths air means that, during a lunar eclipse, sunlight can filter through Earths atmosphere onto the shadow on the moon. This filtered sunlight makes the moon appear red during a total eclipse.

LUNAR ECLIPSE http://www.youtube.com/watch?v=tIE1MTGz4eI&NR=1&feature= endscreen&safety_mode=true&persist_safety_mode=1 http://www.youtube.com/watch?v=tIE1MTGz4eI&NR=1&feature= endscreen&safety_mode=true&persist_safety_mode=1 A lunar eclipse can only occur at full moon and In a lunar eclipse, the total phase can last for a maximum of 1 hour and 40 minutes A lunar eclipse occurs when the Earth passes between the Sun and the Moon. SOLAR ECLIPSE A solar eclipse can only occur at new moon The maximum time of a solar eclipse is 7 minutes 40 seconds. A solar eclipse occurs when the Moon passes between the Earth and the Sun

Slide 12

You can experience partial and total eclipses. Occur a few times each year. Can only occur when the Sun, the Moon, and Earth are lined up perfectly. Occur in lunar/solar pairs! Caused by the revolution of the Moon.
