The convection currents are what causes the movement of the tectonic plates. These currents occur in the mantle layer. Basically, the convection currents are a circular movement of the magma in the mantle which is cause by the difference in temperature and density. The hotter magma moves up because it is less dense, while the cooler magma moves down because it is more dense. This movement continues all the time. The magma that moves up comes in touch with the crust above it. At certain places where the crust is thinner, or there are cracks, under the big pressure from the mantle, the magma manages to penetrate through it, filling up the gaps, and also pushing the plates away. As the plates are pushed more and more, their opposite ends collide with other plates, resulting in subduction, so the crust is getting into the mantle and melts, moving down in the mantle as it is becoming cooler and denser magma, and the process continues on and on.
The latitude of the Antarctic Circle is roughly 66.5 degrees South.
There is one point on the Antarctic Circle at every possible longitude.
I believe it is..

The other ones don't make sense, radiant energy is electromagnetic and gravitational energy. You can't tell how many planets are in its solar system from only this information. The number of galaxies is also impossible to tell. The only other one that could perhaps make sense is the distance to the center of its galaxy. But, this again is disproved as one star can't tell you the position of the center.
My name is jeff and idk about the answer
