- Dr. Luis Alvarez has suggested that the extinction of the dinosaurs
and numerous other species 65 million years ago was caused by severe
temperature drops following the insertion of dust into the atmosphere.
The enormous quantities of dust resulted from an asteroid impact in
the Yucatan area of what is now Mexico. Research this topic and write
a brief report on what you discover.

A departmental site at UC. It clearly lays out its hypothesis and looks
at alternate arguments.
Dinosaur
Volcano Greenhouse Extinction
This site looks at two different theories. Both of these theories deal
with particles in the atmosphere but offer different explanations on
how the particles got there.
The
Journal of Dinosaur Paleontology
Under the section IMPACT THEORIES AND EXTINCTION EVENTS you will find
a number of different articles with topics such as forensic evidence
of asteroid impact and possible impact times.

Airline pilots are often able to use the jet stream to minimize
flight times. Find out more about the importance of the jet stream
in aviation.
NOVA
On-Line
As part of a site that looks at a round-the-world balloon race, NOVA
answers frequently asked questions about the jet stream.
Understanding
Winds, Jet Streams
USA Today gives a description of the jet stream and how it influences
weather. It also gives an in depth discussion of winds, how the et Stream
forms, and how the jet stream affects weather.

This web page looks at how the rotation of Earth and the jet stream
effect flight times. This page specifically looks at a flight back and
forth across North America and whether the effects mentioned above help
or hinder total flight times.
