What is Earth made of? Interestingly enough, we don't exactly know. We can use magnetic fields and seismic waves to measure the densities and movements of material deep in the mantle, liquid outer core, and solid inner core of the Earth, which provides clues about its composition. We know...
Questionable inheritance: What Processes on Planetesimals Mean for the Bulk Composition of the EarthL. Elkins‐Tanton
Diamonds started out as carbon that crystallized deep in the earth under great pressure and temperature. Volcanic activity brought the diamonds to the Earth’s surface in kimberlite magma. Erosion of kimberlite deposits over many years caused the released diamonds and indicator minerals. Advancing and...
The bright colors of the northern lights are dictated by the chemical composition of Earth's atmosphere. "Every type of atom or molecule, whether it's atomic hydrogen or a molecule like carbon dioxide, absorbs and radiates its own unique set of colors, which is analogous to how every human...
Nickel is also found in the earth’s core, making it popular. It shares ferromagnetic properties with steel and iron, and this material has been used to make coins for a long time. Today, nickel is used in many industries.Phonesandbatteriesare just two of the many examples, as this metal...
A comet leaves a trail of matter behind it as it moves through the inner solar system. Some of this debris may get strewn across Earth's orbit around the Sun. When Earth passes through this part of its annual path, it sweeps through the dust trail. The particles enter Earth's ...
This allows comparison between vehicles of different sizes, as powertrain composition is included in the assessment. Complete LCA is also suitable to assess the balance between the electric part and the conventional part of the powertrain in a PHEV, e.g., different all-electric range depending on...
Water isotopes are tracers of convective processes and are often used as proxies for past precipitation. These applications require a better understanding of the impact of convective processes on the isotopic composition of water vapor and precipitation. One way to advance this understanding is to anal...
Spaceships communicate with Earth using radio waves transmitted through space antennas and ground-based antennas. The Deep Space Network is an example of a communication system used to maintain contact with spacecraft beyond Earth's orbit. 3 Share Your Discovery Share via Social Media Embed This Con...
Oil is often called “black gold,” yet crude oil has a range of viscosity and can vary in color from black to yellow depending on its hydrocarbon composition.13Distillation, the process by which oil is heated and separated into different components, is the first stage in refining. ...
