If we feel sweaty, we’ll head for the shade. If our soup’s too hot, we’ll blow on it. If a room’s too stuffy, we’ll open a window. But what are the options when the planet grows too warm? That is the problem — and an enormous one — that Earth and its dwellers now face. It involves hacking the Earth. Smokestacks such as these release visible clouds of water and invisible clouds of carbon dioxide into the air. These researchers propose tinkering with the planet’s climate in several big ways. Geoengineering projects represent examples of thinking big. These planet-scale projects all address the same great challenge: countering the impacts of burning large amounts of coal, oil and other fossil fuels.
Our global ‘greenhouse’ Global warming is real. Trees naturally remove carbon dioxide from the air. Konradlew/istockphoto Once CO2 enters the atmosphere, well above the reach of green plants, it acts as a greenhouse gas. Simply put: Earth is out of balance. Geoengineering. EARTH. Older than Dirt? Every once in awhile, a question makes it to my inbox that’s too good to ignore.
A friend and I were joking about being “older than dirt” and he asked a question I thought you might enjoy: “Hey, ask Ethan how old dirt is and how it got here.” You did the smart thing by coming to me, because the alternative is to ask yahoo. Old as Dirt: 2.7-Million-Year-Old Soil Found Under Ice. Buried thousands of feet under Summit, the highest point on Greenland's ice sheet, is a soil born before humans ever walked on Earth.
FYI: Just How Old is Dirt? Infographic: 50 Unbelievable Facts About Earth. Earth Dashboard. 10 Facts About Planet Earth You May Not Have Known. By Nancy Atkinson on April 22, 2015 Happy Earth Day!
Earth Day is good time to think about the beauty of our home planet and reflect on our stewardship of environmental resources like air and water. Sometimes, though, our planet can be a bit unpredictable. How Can You See a Satellite View of Your House? This is an article from our archive, but we’ve updated it with this spiffy video.
Every now and then I go looking for a free aerial view of my home. It’s amazing what’s available through the internet now, totally free. Thanks to commercial Earth observation satellites, and internet tools that make these photos accessible through the internet, it’s easy to see your house from space. In our modern space age, there are more than 8,000 satellites currently orbiting the Earth. Littoral zone. The littoral zone is the part of a sea, lake or river that is close to the shore.
In coastal environments the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged. It always includes this intertidal zone and is often used to mean the same as the intertidal zone.

Fluorescent Minerals and Rocks: They Glow under UV Light! What is a Fluorescent Mineral?
All minerals have the ability to reflect light. That is what makes them visible to the human eye. Some minerals have an interesting physical property known as "fluorescence". S209 - Earth science - Open University Course. What's included Study materials, including activities and assessment, will be delivered online only.
You will need You will need to draw diagrams, or to annotate by hand, diagrams that you download, and then use either a scanner or a digital camera to produce files of these diagrams to include in your assessment. A printer is desirable, as is a headset with microphone or computer with built-in speakers and microphone. You will also need to purchase two geological maps (costing about £15 in total) using a special order form on the module website. If you take part in a local field tutorial, field-based investigation or the optional 4-day residential school, you will require a hard hat (costing about £5).
Computing requirements You will need a computer with internet access to study this module as the study materials and activities are accessible via a web browser. Ammolite: The Gemstone with Spectacular Color Properties. What is Ammolite?
Gem-quality Ammolite produces a spectacular display of iridescent color when it is observed in reflected light. The colors of an individual stone can run the full range of the visible spectrum or be limited to just one or two colors. The color display can rival fine opal and labradorite in its intensity and beauty. Rock Tumblers: You can tumble rocks into beautiful gemstones! Sunstone - The gemstone with the aventurescent surprise! What is Sunstone? The name "sunstone" is used for specimens of translucent to transparent feldspar that produce bright metallic flashes when light interacts with tiny plate-like mineral inclusions within the stone.
These mineral inclusions usually have a common orientation, and light entering the stone reflects from them at a common angle. This produces a flash of light in the eye of the observer who views them at the proper angle. This optical phenomenon is known as "aventurescence. " The first materials to be called "sunstone" because of their aventurescence were specimens of oligoclase, a plagioclase feldspar.
Are We Causing Earth Changes? Natural disasters are not a message from God but a message from ourselves. The spiritual answer is, “Of course we are, because Mother Nature is disturbed by our lack of love and respect for her.” The scientific answer is, “Of course we are, but only indirectly through decades of reckless pollution.” Everything depends on what level of consciousness dominates your awareness. All answers are tangled, yet in the untangling I believe that science will one day connect Earth changes and human awareness. Low-Tech Geohacking Methods that Changed The World. Storms bring forth prehistoric treasures.

Plastic Manners. Plastic is forever. Before knowing anything else about plastic, the single most important thing to take in is that plastic is forever. Plastic does not biodegrade. Exposed to the elements, it simply breaks down into smaller and smaller plastic bits. Nearly every single item that was ever created, still exists on this planet, and will for thousands of years. Every item that you have ever discarded, will be around long after you are gone. Plastic is pervasive. Wikipedia tells me that “the word is derived from the Greek πλαστικός (plastikos) meaning fit for molding, and πλαστός (plastos) meaning molded.”
Plastics pollute. Single Use plastics and disposable plastics are the main source of plastic pollution. Plastic Manners. Taina Uitto , a Vancouver-based environmentalist and blogger, has taken on a challenge most of us would find daunting: living for a year without any plastics. Whats TOXIC. Easter miracle?
