Garbage If your habits resemble those of average Americans, you generate about 4.6 pounds of solid trash per day. This adds up to big trouble for the environment. Americans are generating waste products faster than nature can break them down and using up resources faster than they can be replaced. Rocks - Kids Discover Run Slideshow Rocks rule! They’re found in our toothpaste, our roads, and even our cereal (in the form of iron). Kids curious about rocks will love this issue, which first takes them through the whole rock cycle – from igneous to sedimentary to metamorphic stages – then leads them right into the center of the Earth to learn about the different rocky layers. Next up: a look at what humans throughout history have done with rocks; for kids who like hearing about amazing feats, the building of the Great Pyramid (out of more than two million limestone blocks!)

Weather New Englanders have a saying: "If you don't like the weather, just wait a minute." Weather forecasts may be more stable in other parts of the world, but the basic idea stands. Weather is dynamic, the product of interacting forces we are only beginning to understand. Witness the weather extremes caused by El Niño in 1997 and 1998. Rock Experiments - Learn About Erosion Frozen Rock Rocks are broken down in all sorts of ways - by wind, rain, rivers, and rock slides. But they are also broken apart by freezing and thawing. When water freezes, it expands. Water that has seeped into a rock will expand when frozen, causing cracks in the rock.
Geo-Primary Assessing Primary Geography Teacher assessment is a complex matter, but here are a few tools to help you with part of the process. Principles and purposes of assessment These are some special assessment tasks devised by teachers in Staffordshire and Derby.

The beaches along the eastern margin of North America are the result of the weathering, erosion, and breakdown of a huge mountain range (the Appalachian Mountains) over the last 300 million years.

Download Sedimentary rock Middle Triassic marginal marine sequence of siltstones (below) and limestones (above), Virgin Formation, southwestern Utah, USA Genetic classification Based on the processes responsible for their formation, sedimentary rocks can be subdivided into four groups: clastic sedimentary rocks, biochemical (or biogenic) sedimentary rocks, chemical sedimentary rocks and a fourth category for "other" sedimentary rocks formed by impacts, volcanism, and other minor processes. Clastic sedimentary rocks UK Official name: United Kingdom of Great Britain and Northern Ireland Location: located off the north-western coast of continental Europe. It spans an archipelago including Great Britain, the northeastern part of the island of Ireland, and many smaller islands.Northern Ireland is the only part of the UK with a land border with another sovereign state, sharing it with the Republic of Ireland Apart from this land border, the UK is surrounded by the Atlantic Sea, the North Sea, the English Channell, and the Irish Sea.
