This resource describes how and where lava plateaus have formed. They will discover that lava plateaus of this type can be seen in southeastern Washington, eastern Oregon, and southern Idaho and that some of these lava flows are exposed and measure more than a mile in total thickness. Students will also learn that during late Miocene and early Pliocene times, one of the largest basaltic lava floods ... Full description.

This handout lists major events in Earth history with approximate ages (in millions of years before present). The calendar date is determined by setting midnight, January 1, to correspond with the formation of the Earth, and setting the following midnight, December 31, to correspond to the present. Thus, the entire history of the Earth is displayed as a single calendar year. Full description.

This article and accompanying questions discusses the fact that several of the Earth's tectonic plates move at about the same speed as fingernails grow - around 35 mm per year - and that the plates are made of lithosphere (crust plus the upper part of the mantle). Students will also learn that beneath the lithosphere is the asthenosphere, part of the upper mantle that is ductile because it contains ... Full description.

This time scale allows students to select multiple time periods from a list and view them on a highlighted display. It shows the relationship between eon, era, period, sub-period, and epoch and also includes the date in mega-annum (Ma) or millions of years before present. The scale reflects the changes in the Cenozoic Era (Tertiary and Quaternary have been eliminated and the Neogene modified) in the ... Full description.

This lesson focuses on global warming and a possible connection with the Paleocene extinction event. Students will explore how a global warming episode associated with the release of methane from methane hydrate deposits could have been responsible for the Paleocene extinction event 55 million years ago. They will be able to describe the overall events that occurred during the Paleocene extinction ... Full description.

This exercise can be used to demonstrate changes in the Earth through time, and the length of time it took for those changes to take place. A list of Important Dates in Earth History is provided that contains the dates of the events shown on a time clock. The teacher can pick events from the list of key events and calculate (or have students calculate) the time for the key events they wish to use. ... Full description.

While commonly referred to as 'shooting stars', meteors and meteor showers are, in fact, unrelated to stars. Instead, these streaks of light are the glow of interplanetary debris crashing into Earth's atmosphere. This animated video introduces students to shooting stars and the reasons behind annual meteor showers. Topics include the difference between sporadic meteors and meteor showers, how comets ...

Earth's surface is covered with natural features formed by weathering, erosion, and deposition. Although these forces are typically associated with destruction, they have also created many of the world's natural wonders. This interactive slide show presents images of natural features (glacial valleys, petrified forests, hot springs, and others) produced by these powerful forces. A background essay ...

If you observe clouds in a portion of the sky, you may notice that they are not static. Clouds are composed of tiny particles of water and are constantly changing and moving. This video lets viewers observe clouds forming, moving, and changing shape. The segment is one minute thirty-three seconds in length. A background essay and list of discussion questions are also provided. Full description.
