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...
Venus is Earth's closest planetary neighbour and both bodies are of similar size and mass. As a consequence, Venus is often described as Earth's sister planet. But the two worlds have followed very different evolutionary paths, with Earth having benign surface conditions, whereas Venus has a ...

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...
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...
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. ...
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...
10.What does paragraph 6 imply about comets that are visible from Earth? A.The visible comets grow brighter as they grow older B.The comets that are visible from Earth today have not been orbiting close to the Sun throughout the history of the solar system ...
The purpose of this review article is to investigate the usefulness of different types of life cycle assessment (LCA) studies of electrified vehicles to pr
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...
