What's the geometric order for a lunar eclipse?

Sun - Earth - Moon

100

What does "solar" mean?

It comes from the Latin word solis which means sun.

100

If the Earth and the moon had the same orbital path how many eclipses would happen per year?

24

What is the darkest part of the shadow? Draw a diagram to show this shadow. 


The Umbra.

How come you are more likely to witness a lunar eclipse than a solar eclipse?

This is because you can be anywhere on the Earth where you can see the moon, but for a solar eclipse, you have to be in a smaller area on the Earth.

200

When does a lunar eclipse occur?

When the Earth is blocking the sunlight from the moon and casting a shadow on it.

What is a solar eclipse?

When the moon casts a shadow on the Earth and blocks the sunlight from a part of the Earth.

If the Earth and the moon had the same orbital path how many eclipses would happen a month?

2

What surrounds the darkest part of the shadow? Draw a diagram to show the lighter portion of the shadow.


The penumbra.

How come you need to protect your eyes during a partial eclipse?

This is because you can still go blind from looking at the sun during partial solar eclipse.

300

What moon phase occurs during a lunar eclipse?

Full moon.

300

What moon phase occurs during a solar eclipse?

New moon.

300

What if the Earth and the moon had the same orbital path?

If this was the case then we would have monthly eclipses because there would be perfect geometry every month.

300

Draw and name this eclipse: the moon isn't casting a large enough shadow on earth because it's further than usual, leaving some visible sun

Annular solar eclipse

300

How come eclipses don't happen consistently?

This is because the moon revolves 5 degrees relative to Earth. Earth and the moon aren't in the same orbital path? Perfect geometry doesn't occur every month.

400

Why is it not necessary to have protective goggles when viewing a lunar eclipse?

Lunar eclipses happen at night. 

400

What kind of solar eclipse occurs when the moon's shadow isn't fully covering the sun and looks like it has a ring on it?

Annular Solar Eclipse

400

What if the moon was moving closer to earth rather than further away?

Partial solar eclipses would eventually be a total eclipse. Also, our tides and oceans would have very large waves.

Every _____ years any given spot on Earth will have a total solar eclipse.


Every 2-4 years.

It is daytime in the western hemisphere. The order of celestial bodies are the sun, earth and moon. One object is entirely in the umbra. Explain what people living in the western hemisphere will see. What will the people in the eastern hemisphere see? Be specific!

Western hemisphere: these people are in day time and won't see anything - it's just a normal day


Eastern hemisphere: everyone on this side will see a total lunar eclipse because the moon is inside the earth's umbra.
