March Madness Grade 6 3. What can we learn by studying fossils? A. how hurricanes formed long ago B. how the solar system was formed C. how strong earthquakes are caused D. how Earth's environments have changed

March Madness Grade 6 4. Extrusive rocks are formed by A. magma cooling on Earth's surface. B. pressures inside Earth. C. the attraction of magnetic particles. D. tidal deposits of sediment.

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

Two kinds: Lunar eclipses Solar eclipses Video clip on eclipses

Shadow has two parts a. Umbra - total darkness where total eclipse occurs. b. Penumbra - part of light is blocked, where partial eclipse occurs.

Two kinds of eclipses a. Lunar- earth casts a shadow on the MOON - occurs only at Full moon b. Solar - 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.

Eclipse animation

Time lapse photography of a lunar eclipse

Animation of solar 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 Eclipses 1.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.
