Answer:
D. Asthenosphere
Explanation:
The asthenosphere is relatively plastic part of the mantle which underlies the brittle lithosphere. In the asthenosphere, it is generally believed that the rocks are in ductile state and easily moves. It is the site of convection within the earth. In mantle convection, hot and light materials rises and keeps moving into upper crustal levels till they solidify. Here also, cold and denser materials sinks deeper till they turn to melt. This differences in temperature and density sets up a convective cell within the mantle. Several convective cells are in the mantle.
Answer:Magnetic fields are invisible, at least usually. But scientists from NASA's Space Sciences Laboratory have made them visible as "animated photographs," using sound-controlled CGI and 3D compositing.
Explanation:
Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulate together in mathematically.
It is given Einstein's special theory of relativity.
It is find the Einstein's special theory of relativity explains the perpendicular behavior of moving charges without recourse to invoking the concept of a magnetic field.
<h2>What is Einstein's special theory of
relativity?</h2>
As we know that one charge creates a field and its that field that actually exerts a force on the other charge. Here we it gives the relationship of two fields like electric field and magnetic field and gives the formula for electromagnetic objects.
Special relativity fixes the problem by the points that the magnetic force in one frame of reference easily be an electric force in other and also some of the combination of them in a frame.
Thus, Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulae together in mathematically.
