3-D maps illustrate formation of the Hangai Dome in central Mongolia

 US,CA
Researchers at Rice University, the University of Toronto, and Princeton University generated 3-D maps of the Earth under the Hangai Dome in central Mongolia from seismic data. The 3-D image below shows the earth under the dome. Colored yellow, warm rock rises up from the deep mantle toward the Earth’s surface. The pressure on the rock drops as it rises. When the rock reaches 150 kilometers (93 miles) below the surface, it starts to melt and form magma, illustrated in red. Heat released by [...]

 GB,
After announcing earlier this week that we are sadly saying goodbye to the EGU network blog Between a Rock and Hard Place, the time has come to find a new blog to take their place. If you are an Earth, planetary or space researcher (a PhD student, an early career scientist, or a more established one) with a passion for communicating your work, we’d like to hear from you! We currently feature blogs in palaeontology (Green Tea and Velociraptors), international development (Geology for Global [...]

Acidity rain is really a natural process and happening around us. Water is an important element and required by life. Nearly 70% from the body’s biological creature is an element water. Therefore, no creature can and biological bio-diversity without water. Water on the top of earth by its character is split into two, namely freshwater […] The post The Occurrence of Acid Rain appeared first on Liberty, Equality, and

Knowing that NASA,NOAA, and EVERY major scientific society on Earth says that we must immediately reduce our emissions of Carbon, or risk dangerously changing the planet’s life support system, you’d expect that at least one question in the debate Thursday night would be about that subject. You’d be wrong. Now, I could understand skipping something real difficult, like is the Earth over a million years old?, or are the fossils

This is NOT a killer asteroid entering the Earth's atmosphere. It is a sun dog over Oak Flat Campground near Superior, Arizona. Oak Flat is going to become a gigantic crater. Because it won't be a meteor that causes it. It won't be an atomic bomb test. And it won't be because of aliens like those stupid ones in Indiana Jones and the Kingdom of the Crystal Skull. The giant crater will

 US,
We are in Georgia gearing up for the second phase of field work for the SUGAR project, which will involve collecting seismic refraction data along two profiles spanning eastern Georgia. In the coming weeks, we’ll deploy thousands of small seismometers along county and state roads across the region, which will record sound waves generated by a series of controlled blasts. We can use the sound waves to make pictures of geology beneath the surface. Geological structures beneath Georgia record [...]

Forty-six years ago today I set beside my Great Grandmother, who walked to Indian Territory (now Oklahoma) behind a covered wagon, and listened to Armstrong and Aldrin land on the Moon. While the photos of the Moon from the Apollo astronauts were dramatic, it was the pictures they took looking back at Earth that changed the way we think about our planet. Today, we got another one of those photos

'A screaming roller coaster; how fast am I travelling (due to Earth's spin and Earth's orbit)?' After the class roller-coaster experience, ask your pupils ‘Why were we acting like this?’ The answer is that you are all travelling very fast towards the East - due to the spin of the Earth. If you are on the Equator you are travelling at 1,674.4 km/h. To calculate how fast you’re

When the term “World’s Tallest Structure” is mentioned most people immediately think of a “skyscraper” or a tall building. The Burj Khalifa, a skyscraper in Dubai, holds the title of the world’s tallest building with an amazing height of 2717 feet. However, if you consider any structure that extends upwards from Earth’s surface, many deepwater
