Topics include how seismic tomography can provide clues to scientists about mantle dynamics in the aftermath of an earthquake including variations in seismic velocities, the influence of temperature in Earth's upper mantle, and a brief overview of a study by Schuberth and colleagues focusing on ...
How does the asthenosphere move? Asthenosphere: The asthenosphere is a part of the mantle of the Earth, the layer of super-heated rock found directly below the crust of the Earth and above the core. The asthenosphere is the uppermost part of the mantle. ...
The mantle is extremely hot, but for the most part, it stays in solid form because the pressure deep inside the planet is so great that the material can't melt. In certain circumstances, however, the mantle material does melt, forming magma that makes its way through the outer crust. ...
How does water create magma during subduction at a divergent boundary? In other words, how does water chemically lower the melting point of the asthenosphere to create magma and thus create a volcano? How does magma move under the Earth's crust?
How did the moon form? How long does it take the moon to orbit Earth? How far is the moon from Earth? We tackle all of these questions (and more) in our guide.
“The impacts of the Climate Crisis are being felt in all regions across our country — extreme weather, heat waves, deeper and longer droughts, crop failures, strengthening wildfires, sea level rise — and they are disproportionately borne by the most vulnerable among us,” former Vice President...
The Heat’s Role In the world of lava lamps, the heat usually comes from a light bulb tucked at the bottom. This bulb does more than just shine; it warms the denser of the two liquids. As this liquid heats up, it expands and becomes lighter, prompting it to float to the top of ...

Watt acknowledges that with so many challenges, it’s important for a concerned artist to focus on the issues that move them the most, and where they can make the biggest difference. "Jack Johnsonisa great example," he says. While John...
If you think your dream of building a fireplace in your home is too far-fetched, think again. Electric fireplaces not only bring us clean, efficient heat, but have made the DIY fireplace possible for anyone with a little time and a few resources. Building a corner fireplace is a fast and...
