  • Geological Timeline
    Geological Timeline In this pack you will find information and activities to help your class grasp the concept of geological time, just how old our planet is, and just how young we, as a species, are. Planet Earth is 4,600 million years old. We all know this is very old indeed, but big numbers like this are always difficult to get your head around. The activities in this pack will help your class to make visual representations of the age of the Earth to help them get to grips with the timescales involved. Important EvEnts In thE Earth’s hIstory 4600 mya (million years ago) – Planet Earth formed. Dust left over from the birth of the sun clumped together to form planet Earth. The other planets in our solar system were also formed in this way at about the same time. 4500 mya – Earth’s core and crust formed. Dense metals sank to the centre of the Earth and formed the core, while the outside layer cooled and solidified to form the Earth’s crust. 4400 mya – The Earth’s first oceans formed. Water vapour was released into the Earth’s atmosphere by volcanism. It then cooled, fell back down as rain, and formed the Earth’s first oceans. Some water may also have been brought to Earth by comets and asteroids. 3850 mya – The first life appeared on Earth. It was very simple single-celled organisms. Exactly how life first arose is a mystery. 1500 mya – Oxygen began to accumulate in the Earth’s atmosphere. Oxygen is made by cyanobacteria (blue-green algae) as a product of photosynthesis.

  • What Killed the Dinosaurs?
    What killed the dinosaurs? The impact theory The impact theory was beautifully simple and appealing. Much of its evidence was drawn from a thin layer of rock known as the 'KT boundary'. This layer is 65 million years old (which is around the time when the dinosaurs disappeared) and is found around the world exposed in cliffs and mines. For supporters of the impact theory, the KT boundary layers contained two crucial clues. In 1979 scientists discovered that there were high concentrations of a rare element called iridium, which they thought could only have come from an asteroid. Right underneath the iridium was a layer of 'spherules', tiny balls of rock which seemed to have been condensed from rock which had been vapourised by a massive impact. On the basis of the spherules and a range of other evidence, Dr Alan Hildebrand of the University of Calgary deduced that the impact must have happened in the Yucatan peninsula, at the site of a crater known as Chicxulub. Chemical analysis later confirmed that the spherules had indeed come from rocks within the crater. The impact theory seemed to provide the complete answer. In many locations around the world, the iridium layer (evidence of an asteroid impact) sits right on top of the spherule layer (evidence that the impact was at Chicxulub). So Hildebrand and other supporters of the impact theory argued that there was one massive impact 65 million years ago, and that it was at Chicxulub. This, they concluded, must have finished off the dinosaurs by a variety of mechanisms.

  • “Impact Winter” Guest: Ben Murray [Intro Music] JOSH: Hello, You're Listening to the West Wing
    The West Wing Weekly 6.09: “Impact Winter” Guest: Ben Murray [Intro Music] JOSH: Hello, you’re listening to The West Wing Weekly. I’m Joshua Malina. HRISHI: And I’m Hrishikesh Hirway. Today, we’re talking about Season 6 Episode 9. It’s called “Impact Winter”. JOSH: This episode was written by Debora Cahn. This episode was directed by Lesli Linka Glatter. This episode first aired on December 15th, 2004. HRISHI: Two episodes ago, in episode 6:07, the title was “A Change is Gonna Come,” and I think in this episode the changes arrive. JOSH: Aaaahhh. HRISHI: The President goes to China, but he is severely impaired by his MS. Charlie pushes C.J. to consider her next step after she steps out of the White House, and Josh considers his next step after it turns out Donna has already considered what her next step will be. JOSH: Indeed. HRISHI: Later in this episode we’re going to be joined by Ben Murray who made his debut on The West Wing in the last episode. He plays Curtis, the president’s new personal assistant to replace Charlie. JOSH: A man who has held Martin Sheen in his arms. I mean, I’ve done that off camera, but he did it on television. HRISHI: [Laughs] Little do our listeners know that Martin Sheen insists on being carried everywhere. JOSH: That’s right. I was amazed all these years later when Martin showed up for his interview with us that Ben was carrying him. That was the first time we met him.

Roosenburg Poplar Island Environmental Restoration Project is a unique solution for the dredge material placement and restoring decreasing habitat in the Chesapeake Bay. Since 2002, a long-term terrapin monitoring program has been documenting diamondback terrapin, Malaclemys terrapin habitat use. Northern diamondback terrapins, hatchlings may either emerge from their nest in the fall and seek other overwintering hibernacula, or remain inside their natal nest to emerge the following spring, known as delayed emergence. Results from the 2007-08 nesting season found that compaction and the presence of ice nucleating agents (as a measure of crystallization temperature) affected nest emergence timing in hatchlings. Fall emerged nests had lower bulk density (less compacted) and had a higher potency of ice nucleating agents compared to spring emerging nests. With proper management, areas such as Poplar Island may become areas of concentration for terrapins and thus provide a source population for the terrapin recovery throughout the Bay.

  • Natural and Cultural Resources
    2010 Comprehensive Land Use Plan Natural and Cultural Resource Values Chapter 5 Natural and Cultural Resources Maine supports a wide variety of natural and cultural resources. There are vast forestlands, lakes, mountains, islands, tidal and inland wetlands, and special cultural resources. Many of the most spectacular of these features are located in the Commission’s jurisdiction. Some features date back to earlier geologic times, while others reflect human intervention. All are part of the ever-changing ecosystems which collectively comprise the state’s resource base. Each natural resource has economic, recreational and ecological values and is, therefore, subject to conflicts over decisions about land use and resource allocation. This chapter contains detailed descriptions of many of the jurisdiction’s natural and cultural resources, and discussion of the issues pertaining to them. 144 2010 Comprehensive Land Use Plan Natural and Cultural Resource Values 5.1 Agricultural Resources Despite its limited presence, agriculture is important to the jurisdiction. Agriculture makes a significant contribution to local and regional economies, and is an important part of the culture and heritage of many rural areas. Working farms keep significant lands in open space and help to maintain the tradition of the jurisdiction as a place where resource-based uses predominate. A relatively small portion of the area within the jurisdiction is used for agricultural production. A number of factors contribute to agriculture's limited presence here: The availability of seasonal and trained year-round workers is limited; productivity is constrained by weather, soils which are poorly suited to agriculture, and the lack of large contiguous tracts of suitable land; and processing services and distribution centers are difficult to access without high-volume production.

  • The Comet/Asteroid Impact Hazard: a Systems Approach
    THE COMET/ASTEROID IMPACT HAZARD: A SYSTEMS APPROACH Clark R. Chapman and Daniel D. Durda Office of Space Studies Southwest Research Institute Boulder CO 80302 and Robert E. Gold Space Engineering and Technology Branch Johns Hopkins University Applied Physics Laboratory Laurel MD 20723 24 February 2001 The Comet/Asteroid Impact Hazard: Chapman, Durda, and Gold A Systems Approach February 2001 EXECUTIVE SUMMARY The threat of impact on Earth of an asteroid or comet, while of very low probability, has the potential to create public panic and – should an impact happen – be sufficiently destructive (perhaps on a global scale) that an integrated approach to the science, technology, and public policy aspects of the impact hazard is warranted. This report outlines the breadth of the issues that need to be addressed, in an integrated way, in order for society to deal with the impact hazard responsibly. At the present time, the hazard is often treated – if treated at all – in a haphazard and unbalanced way. Most analysis so far has emphasized telescopic searches for large (>1 km diameter) near-Earth asteroids and space-operations approaches to deflecting any such body that threatens to impact. Comparatively little attention has been given to other essential elements of addressing and mitigating this hazard. For example, no formal linkages exist between the astronomers who would announce discovery of a threatening asteroid and the several national (civilian or military) agencies that might undertake deflection. Beyond that, comparatively little attention has been devoted to finding or dealing with other potential impactors, including asteroids smaller than 1 km or long-period comets.

Meteors crash into Earth’s atmosphere every day, but almost all crumble into dust before they reach the surface. Occasionally, a larger fragment, called a meteorite, makes it all the way to Earth’s surface. There have been cases of people injured and property damaged by meteorites. One of the more spectacular recent atmospheric impacts occurred over Chelyabinsk, Russia, in 2013. The meteor exploded in the air, generating a shockwave that shattered windows all over the city, sending over a thousand people to the hospital. To make matters worse, the impact occurred in February, during very cold weather, and it was hard to heat those homes until the windows could be repaired.
