When I am at the sea, I always ask myself, why the sun reflects on the water pointing directly towards me, no matter where I am standing. I could take two pictures from different points at the same time and the shining stripe on the water would be different in both pictures. Why that?

This occurs because of two reasons. The first is the size of sun is very very large and the second is the rays coming from the sun is uniform for local area. So irrespective of the local distance you will get the same intensity and that is why whenever you stand, you will see the sun pointing toward you only.

Aurora is basically a phenomenon in the dark night sky at the poles of the Earth which is due to the incidence of highly energetic charged particles like Electrons, protons etc. from the space in to the Earth's magnetic field. Moreover, this occurs only at poles of the Earth because our planet works like a magnet having both north and a south pole. So Aurora is basically due the interaction of charged particle with the Earth's Magnetic field.

I just want to add, that the magnetic filed is less protective near the poles. So more particles from the sun can reach the earth's atmosphere. When these particles hit the oxygen in the atmosphere the oxygen glows greenish.
