Anywhere lavas have cooled, these magnetite crystals point to the magnetic poles. The little magnets point to where the north pole was when the lava cooled. Scientists can use this to figure out where the continents were at that time. This evidence clearly shows that the continents have moved. During Wegeners life, scientists did not know how the continents could move. Wegeners idea was nearly forgotten. But as more evidence mounted, new ideas came about. | 0.217172 |

The moon does not produce its own light. However, the moon becomes visible to us due to its capability to reflect light from the sun. As it moves around the Earth, we see these phases that result from the different angles the moon makes with the sun. A New Moon occurs when the side of the moon facing the earth is not illuminated by the sun. After a few days, a thin crescent shape of the moon becomes visible in the night sky. The crescent moon waxes, or appears to grow fatter, each night. When half of the moon is illuminated, it is called a First Quarter moon. The moon continues to wax, forms a gibbous shape, until it eventually becomes a Full Moon. This now means that the moon has completed one half of a month. During the second half, the shape of the moon starts to wane, growing thinner every night. Once the moon reaches the Third Quarter, it shows the other half of its disc that is illuminated by the sun. It continues to wane while nearing its approach to the New Moon Phase. The Moon undergoes a complete cycle of phases about every 29.5 days. | 0.208904 |
