Plate Tectonics - Crust, Lithosphere, Mantle
Topics Plate Tectonics Crust Lithosphere Mantle Density Buoyancy Earth Science Description Explore how plates move on the surface of the earth. Change temperature, composition, and thickness of plates. Discover how to create new mountains, volcanoes, or oceans! Sample Learning Goals Describe the differences between oceanic and continental crust, including their respective properties of density, composition, temperature and thickness.Predict how changes in composition and temperature change crust density and buoyancy.Draw a time series for different types of plate boundaries and their motions, indicating the related surface features.Deduce the type of plate boundary given images or descriptions of surface features.Explain which types of plate boundaries create crust, and which destroy crust Version 1.02 Related:  Earth Sciences

Here are the Home Demos, the experiments you should try at home sometime. We call them demonstrations (demos for short), because we hope we already know what’s going to happen. Keep clicking around and you’ll find the Episode Guides. We’ve also made it easy for anyone to select from a number of Printable One Sheets. My latest project is about math. Challenge yourself.

Europa’s ocean: Evidence of Jupiter’s moon ocean found on the surface. Image credit: NASA/JPL-Caltech He killed Pluto, but he may have just breathed life into Europa exploration. Astronomer Mike Brown*—discoverer of the giant outer-solar-system iceball Eris which is what started the machinery that kicked Pluto out of the planet club—has found some pretty strong evidence that Jupiter’s moon Europa has sprung a leak. Its undersurface ocean may be mixing with the icy surface, making it possible to understand its composition without having to dig down through dozens of kilometers of solid ice. Mind you, we’ve been eyeballing Europa’s ocean as a potential habitat for life for decades. This evidence that the surface ice and undersurface ocean are in intimate contact comes in a series of steps, which I outline below. Image credit: NASA/JPL/Galileo The water is kept liquid by heating via tidal forces, the effects of the gravity of its massive parent planet. The new data taken by Brown and his colleague Kevin Hand indicate that ocean is much like Earth’s: salty.

Free Lesson Plans For The Environment The environment is a hot topic – in the news, in politics, and in schools, especially in STEM . Since many aspects of environmental issues are practical, everyday things that even younger students can see, the topic lends itself well to a variety of teaching methods like Project Based Learning and Challenge Based Learning . We recently stumbled upon a great resource that will give you some great ideas and lesson plans relating to the environment that can work regardless of how you’re planning on integrating the information into the curriculum. Classroom Earth (which is a program of the National Environmental Education Foundation) is a site that serves as a virtual library for useful web sites, videos, and lesson and unit plans. The Green Reading List This is a list of great environmental reads. PLT GreenSchools! The Project Learning Tree website offers a number of assessment forms, tools, and other resources for conducting quantitive research in your school on environmental topics.

MA weather The Mayan Calendar - an explanation Cyclical: One of the wheels in the Mayan Calendar © Count down to the end of the Mayan calendar using our Mayan Calendar Countdown. The Mayan calendar moves in cycles with the last cycle ending in December 2012. Count down the seconds to “the end” The best doomsday prophecies in history The last day of the Mayan calendar corresponds with the Winter Solstice (or December Solstice), which has played a significant role in many cultures all over the world. The Maya didn't invent the calendar, it was used by most cultures in pre-Columbian Central America – including the Maya – from around 2000 BC to the 16th century. Wheels working together The Mayan Calendar consists of three separate corresponding calendars, the Long Count, the Tzolkin (divine calendar) and the Haab (civil calendar). The three calendars are used simultaneously. The Haab The Haab is a 365 day solar calendar which is divided into 18 months of 20 days each and one month which is only 5 days long (Uayeb).

KML Archive Introduction I am a British/American volcanologist, neogeographer and undergraduate educator. My scientific interests incorporate a mixture of physical volcanology, geomorphology, remote sensing and other geospatial tools, such as Google Earth. My goals are to promote understanding and of the form and processes of the world around us through the use of innovative technologies. Map Data Map data ©2014 Google Map Currently I am a research faculty member in the Geography Department at the University of Alaska Fairbanks (UAF). potassium Weather - Interactive 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. El Niño raised water temperatures in the Pacific and the effects were felt worldwide: crop failures, disease outbreaks, excess snow, or too little rain. Weather may change on a daily basis, but climate changes over geologic time. Join us as we explore the forces behind the weather.

Climate Science Info Zone - There are many institutions and organisations around the world researching climate science, how our climate is changing, and ways of responding. Here are just a few… British Antarctic Survey (BAS) Department for the Environment, Food and Rural Affairs (Defra) Department of Energy and Climate Change (DECC) Energy Saving Trust (EST) Environmental Change Institute (ECI) European Space Agency (ESA) The Geological Society (GS) Grantham Institute for Climate Change (GICC) Intergovernmental Panel on Climate Change (IPCC) Met Office (MO) National Academy of Sciences (NAS) National Aeronautics and Space Administration (NASA) National Oceanic and Atmospheric Administration (NOAA) National Oceanography Centre (NOC) The Royal Society (RS) Tyndall Centre for Climate Change Research (TCCCR) UK Climate Impacts Programme (UKCIP) United Nations Framework Convention on Climate Change (UNFCCC) World Climate Research Programme (WCRP) World Meteorological Organization (WMO)

A History of Climate Science Skeptical Science takes a different approach to Naomi Oreskes' Science paper who sorted her papers into "explicit endorsement of the consensus position", "rejection of the consensus position" and everything else (neutral). In this case, the backbone of our site is our list of climate myths. Whenever a climate link is added to our database, it is matched to any relevant climate myths. Therefore, each link is assigned "skeptic", "neutral" or "proAGW" whether it confirms or refutes the climate myth. This means a skeptic paper doesn't necessarily "reject the consensus position" that humans are causing global warming. There are a large number of neutral papers. So yes, categorisation can get a little complicated and I expect there will continue to be discussion on the issue of classification.
