Simplified diagram of Earth approaching a comet*s dust trail. In this diagram you are looking down onto the Earth*s North Pole. Note how the morning side of Earth will plow into the dust but the evening side will be somewhat shielded. This is why there are often more visible meteors after midnight - you are then on the side of the Earth that is plowing into the dust.

What Is Sea Glass?
November 16 | RockTumbler.com
sea glass
A stack of beautiful blue and green "sea glass" that was naturally tumbled in the ocean by wave or current action. Notice how its surface has a "frosted glass" appearance and how the pieces have a curvature inherited from a glass container. The name "sea glass" is used for glass that has been naturally tumbled in the ocean. The name "beach glass" is used for glass that has been naturally tumbled along the shore of a lake or a river. These glasses are desired by collectors and often used for jewelry or craft projects. Photo by Jodie Coston and copyright by iStockphoto.

What is Horizontal Drilling?
November 15 | Geology.com
horizontal drilling
Directional drilling can be used to reach targets that cannot be drilled with a vertical well. For example, it may not be possible to get a drilling permit for a well located within a populated area. However, a well could be drilled just outside of the populated area and then steered directionally to hit the target.
