Meteorology Earthquake Facts for Kids - Interesting Information about Earthquakes Earthquakes involve the powerful movement of rocks in the Earth’s crust. The rapid release of energy creates seismic waves that travel through the earth. Scientists use the different speeds of seismic waves to locate the epicentre (the point on the surface directly above where the earthquake originated) of earthquakes. Seismometers are used to measure the magnitude of earthquakes. Interactive Ear tool showing how the ear works by Amplifon The ear is the organ which controls hearing and balance, allowing us to understand our surroundings and position ourselves correctly. It is split into three parts: outer, middle and inner. This guide will take you through each part of the ear in turn, answering those essential questions – what are the parts, what do they do, and how? Pinna Helix Antihelix Concha Antitragus Lobe Cartilage Temporal Muscle (Temporalis) Temporal Bone Semicircular Canals Ganglia of the Vestibular Nerve Facial Nerve Ear Canal (External acoustic meatus) Mastoid Process Internal Jugular Vein Styloid Process Internal Cartoid Artery Eardrum (Tympanic Membrane) Auditory Tube (Eustachian Tube) Outer Ear – Welcome to the Interactive Ear! This is the part of the ear that people can see, and funnels sound into your ear canal. The rim of the pinna. A curved panel of cartridge. Bowl-shaped part of pinna. The small, hard bump above your ear lobe. The earlobe contains a large blood supply, helping to keep the ears warm.

Incredible shots of snowflakes in an electron microscope Hydrologists study the snowflakes' composition to understand their effects on ecosystemNaturally occurring snowflakes are collected outside Maryland research center and shipped in By Nina Golgowski Published: 02:55 GMT, 20 August 2012 | Updated: 15:20 GMT, 20 August 2012 Photographed using a specialized microscope whose viewing stage is chilled to -170C, scientists in Maryland are showing a whole new side to what's caught on the tip of our tongues. Using a low-temperature scanning electron microscope, researchers at the Beltsville Agricultural Research Center have captured an astonishing new view on naturally-occurring snowflakes. Shipping in the samples collected from snow banks or during fresh snow fall from around the country, the researchers study their composition for their effects on our ecosystem. Scroll down for video Full-frontal: These unique images captured with a low-temperature scanning electronic microscope capture show a side to snowflakes rarely seen before

Come play again tomorrow! emu.arsusda: Electron Microscopy Unit Snow Page The following images were obtained using a Low Temperature Scanning Electron Microscope (LT-SEM) that is located in the Beltsville Agricultural Research Center in the Electron Microscopy Unit, Bld. 465, Beltsville Maryland 20705. Information gained from studying the structure of snow is vital to several areas of science as well as to activities that affect our daily lives and is only one of several agricultural research projects that are currently being pursued in this research unit.

Earthquakes A Terrifying, Fascinating Timelapse of 30 Years of Human Impact on Earth - Emily Badger A new interactive project from Google, NASA and the US Geological Survey. Since the 1970s, NASA and the U.S. Geological Survey have been amassing satellite images of every inch of our planet as part of the Landsat program. If you could thumb through these historic pictures as if in a flip book, they would show stunning change across the earth's surface, in both our natural environments and our man-made ones. Landsat images taken between 1984 and 2012 have been converted into a seamless, navigable animation built from millions of satellite photos. Below are a few of the GIFs Google has created showing some of the most startling pockets of change: You can also zoom in to any spot on the planet – your hometown, the Amazon, your favorite Chinese mega-city – and watch the same three-decade timelapse unroll. The above image shows Dubai in 2011.

Weather Watch is a fun, interactive tool for students. It is great for a Friday or a day when full attention might be hard to maintain. The activities allow students to manipulate the weather, investigate weather related topics, and make weather inquiries and predictions. Scholastic provides interactive activities on a variety of other topics as well. by kalebclyatt Apr 23
