Cool Sites on Geology! Khan Academy – Earth Geological and Climatic History Geology Shop What is the Earth made up of and how do we know? What causes the seasons? Are there longer-ranging cycles in Earth’s climate? A portfolio of some of the best websites worldwide for geologists, selected for you by a professional geologist. Annenberg Learner – The Rock Cycle Discover rock secrets through these activities. Create a rock collection as you learn about the three main types of rock, find out how to tell the different rock types apart, and see how rocks change from one type into another! OpenLearn – Geology The Open University’s free learning resources in the field of Geology. You can explore all sorts of videos and articles as well as complete some free courses. Plate tectonics Is it a coincidence that Africa and South America could fit like puzzle pieces? Why do earthquakes happen where they do? What about volcanoes and mountains? Are all of these ideas linked? Yes, they are. This tutorial on plate-tectonics explains how and why the continents have shifted over time. In the process, we also explore the structure of the Earth, all the way down to the core. Seismic waves and how we know earth’s structure How do we know what the Earth is made up of? Has someone dug to the core? No, but we humans have been able to see how earthquake (seismic) waves have been bent and reflected through our planet to get a reasonable idea of what is down there. Earth’s rotation and tilt What causes the seasons? Even more, can Earth’s climate change over long period just to “wobbles” in its orbit? This tutorial explains it all. You’ll know more about orbits (and precession and Milankovitch cycles) than you ever thought possible. Have fun! National Atlas – Geology MIT: Open Courseware This site contains both information and articles about Geology but also a wide range of geological maps for you to view. Introduction To Geology This course introduces students to the basics of geology. Through a combination of lectures, labs, and field observations, it will address topics ranging from formation of the elements, mineral and rock identification, and geological mapping to plate tectonics, erosion and climate engineering. The Dynamic Earth Special Topics in Earth, Atmospheric, and Planetary Sciences: The Environment of the Earth’s Surface A great variety of processes affect the surface of the Earth. Topics to be covered are production and movement of surficial materials; soils and soil erosion; precipitation; streams and lakes; groundwater flow; glaciers and their deposits. The course combines aspects of geology, climatology, hydrology, and soil science to present a coherent introduction to the surface of the Earth, with emphasis on both fundamental concepts and practical applications, as a basis for understanding and intelligent management of the Earth’s physical and chemical environment. Nearly 4.6 billion years ago, within a vast cloud of interstellar space, a small pocket of gas and dust collapsed under its own gravity, and our Solar System was born. In this interactive experience, explore the dynamic forces that formed – and are continually reforming – the Earth and our Solar System. 12 | FUSE Earth, Atmospheric, and Planetary Sciences The department of Earth, Atmospheric and Planetary Sciences explores the the solid earth, fluid earth, the biosphere, and their interactions, as well as planetary science, solar system dynamics, and observational astronomy. You can find a huge range of courses here, for free, ranging in difficulty. There really is something for every budding geologist! Geology Apps GeoTime Android – FREE iGeology iPad, iPhone, Android – FREE Simple and easy to use OFFLINE geological time scale. Relative time (chronostratic) subdivisions of the Earth’s geology versus absolute time (chronometric) in millions of years for the entire Phanerozoic. Some basic information on climate, animals and geology are included. iGeology is for anyone who wants to explore their local geology, at street-level scale, virtually anywhere in the UK. Amateur geologists, walkers and gardeners can look at what’s in their local area, to find out about the rocks at the surface (superficial deposits) or the bedrock beneath. Search on place names or the postcode where you live, then click on the map and reveal the rocks beneath your feet. iGeology will locate your iPhone or iPad (if GPS is enabled) and zoom to your location. EarthViewer iPad, iPhone – FREE What did Earth’s continents and oceans look like 250 million years ago, or even 1 billion years ago? What do we know about the climate back when our planet formed? EarthViewer is like a time machine for exploring Earth’s deep history. Based on the latest scientific research, it lets you scroll through the last 4.5 billion years with your fingertips. Follow a favorite landmark, be it Greenland or New York City, as its position shifts through time, or watch a famous fossil like Tiktaalik make an incredible journey from its origin to its current location. Layer your view of shifting continents with data on atmospheric composition, temperature, biodiversity, day length, and solar luminosity, to get a more complete view of our dynamic planet. Mineral Identifier iPad, iPhone – FREE Mineral Identifier is a app used for identifying minerals using the optical properties of minerals, when studied in thin section using an optical microscope. It is a great tool for any budding Geology student which can save a lot of time in identifying minerals and in looking up optical properties of specific minerals. It works by asking a series of questions which can be easily answered when the mineral is studied in thin se
