WHAT IS A SOLAR ECLIPSE?
A solar eclipse occurs when
the moon comes in between the Sun and the Earth
The moon blocks the light from the sun and
a shadow of the moon is cast over Earth.
3.
WHO DISCOVERED THE TRUTH ABOUT SOLAR ECLIPSES?
The first recorded scientific observation of a total solar eclipse
Was in 1605 and it was johannes kepler who recorded it.
Couldn't really find the answer to the question.
4.
WHAT DID ANCIENT CIVILIZATIONS THINK ABOUT IT?
Many ancient civilization thought that the
Occurence of an solar eclipse was a demon eating the sun
They thought that if they made enough noise would scare the
Demon that was consuming their sun away.
5.
WHAT CAUSES A SOLAR ECLIPSE?
A solar eclipse is a natural phenomenon
When the moon passes between the sun and earth
Causing the sun to become fully/partial covered.
Eclipses are regular occurence made possible by the elliptical(oval shaped)
Orbit of the moon around earth and earths elliptical orbit around the sun.

Untitled Slide
In addtion the suns diameter in comparison of the moon is that
The sun is 400 times bigger than the moon
But is also 400 times farther away from the earth than the moon.
Which make eclipses even possible to occur and even more impressive.

WHY DONT SOLAR ECLIPSES OCCUR EVERY MONTH?
Solar eclipses dont occur every month because
The 3 objects; the moon, the sun and the earth dont
Align with each other every month
They only occur when the 3 objects are perfectly lined up.
9.
WHY DOESNT ALL OF THE EARHT SEE THE SAME ECLIPSE?
This happens because of the umbra and the penumbra of the moon.
The umbra and the path of totality are the only ways you can see total eclipses
And the path of totality are only a small bit of the earth.
The penumbra of the moon is where you can see partial solar eclipses
The penumbra are spread over much more area than the umbra so that is why all of the earth can see the same eclipse.
10.
WHY SHOULD PEOPLE LOOK DIRECTLY AT A SOLAR ECLIPSE?
At first: people should not look directly at a solar eclipse as
That will damage your eyes because the suns UV light still comes in to your eyes
And that will make you blind.
So dont look directly at a solar eclipse without some sort of professional equipment
11.
