Quiz

WHY DO WE ALWAYS SEE THE SAME SIDE OF THE MOON?

Shadow has two partsa. _________ - total darkness

where total eclipse occurs.b. ________ - part of light is

blocked, where partial eclipse occurs.

Two kinds of eclipsesa. ______________- earth casts a shadow on the

MOON - occurs only at Full moonb. ______________ - moon casts a shadow on

earth - occurs only at new moon.3. Amount of light blocked is not always the same,

causes total and partial eclipses.

Time lapse photography of a lunar eclipse

Diamond ring effect just before or after a total solar eclipse.

This animation shows the relative sizes of the partial and total eclipse areas. The small, black dot is the umbra. You can see why not many people ever see a total eclipse.

This is a space shuttle photograph of an area of the Earth having a total solar eclipse.

Types of Solar Eclipses1. Total Solar Eclipses occur when the umbra of the Moon's

shadow touches a region on the surface of the Earth. 2. Partial Solar Eclipses occur when the penumbra of the

Moon's shadow passes over a region on the Earth's surface.

3. Annular Solar Eclipses occur when a region on the Earth's surface is in line with the umbra, but the distances are such that the tip of the umbra does not reach the Earth's surface.

Eclipse Movie

Notice that the earth goes through “phases” if you are on the moon.

Video clip of lunar formation

Evidence from the composition (what it is made of) shows that the moon was formed by a collision of an object the size of Mars hitting the earth. The material that blasted into space began to orbit the earth and eventually collected up to form the moon.

•Material on the moon is like our crust and mantle. Very little iron is there.•No atmosphere on the moon due to high energy impact.•Same oxygen atoms are on the earth and moon that are different from ones found in comets and meteoriods!

Collision Theory Evidence !

Stats of the Moon:1. One fourth

earth's diameter

2. Has 1/6 of our gravity

3. Is 250,000 miles away

4. Laser mirror left on the moon used to measure distance.

5. We also measure moonquakes.

Goal was to put men on the moon to explore and conduct scientific experiments.

Neil Armstrong was the first person to walk on the moon. He did so on July 20, 1969.

Remember!

No atmosphere therefore no weather and the sky is black even

during the day.

Lunar far side looks very different from the side of the moon we always see!

Moonquakes occur because of the earth pulling on the moon. They are called “rock tides.”
