Learn facts about Earth's core. Discover what the center of the earth is made of and examine the importance of Earth's core's temperature and magnetic field. Related to this Question What is the density of the
The exosphere is also the region where some satellites orbit, particularly those designed for long-term observations of Earth or communications. The low density of particles in this layer means that there is minimal drag on these satellites, allowing them to maintain their orbits for extended period...
The geometry of the universe is determined by the density of matter within the universe. Albert Einstein'stheory of general relativitydescribes how matter can curve space, so the matter's density can control the curvature and geometry of space on the largest scales. The key value is the "crit...

Auroras tell us many things about Earth's upper atmosphere, including its density, composition, flow speeds, and the strength of electrical currents flowing in the upper atmosphere. These in turn tell us about the Earth's magnetic field, how it extends into space, and how it changes dynamicall...

What is the average density of the earth? M = 5.97 x 1024 kg , R = 6370 km Average density of earth: If the mass of a object is M and volume of that object is Vthen the density of the object is ρ=MV. To solve the given problem we will find the volume of...
Chromium –If you define a metal's strength simply on the basis of how hard it is, then chromium, which scores 9.0 on the Mohs scale, would top your list. By itself, it isn't as strong as other metals in terms of yield and tensile strength, but it is often added to alloys to ma...
