1) Does variability of geomagnetic field in time and in a wide range of periods – from minutes to hundreds and thousands of years reflect a complicated of physico – chemical phenomena in the core, lithosphere, ionosphere and magnetosphere of the earth?
2) Are data ongeomagnetic variations with the periods over 1 year, the so – called secular variations (SV), widely used?
3) In general, geomagnetic field variations can be considered as a vector sum of the fields from different sources, can't they?
4) Are there distinctly distinguished global, regional and local components?
5) Do global peculiarities or focuses of SV embrace areas of thousands of kilometers and have their sources in the earth's core?
6) Regional and local effects are determined by modern physico – chemical, geodynamic and electromagnetic phenomena in the earth's crust and upper mantle, aren't they?
7) What is determined by modern physico – chemical, geodynamic and electromagnetic phenomena in the earth's crust and upper mantle?
8) Does the existing chain of magnetic observatories on the territory of Europeallow to study in details the global and regional effects in SV?
9) The local anomalies of SV or the so – called tectomagnetic effects were studied, as a rule, in geodynamic and seismoprognostic testing grounds, weren't they?

John: Hi, Pengy.
Penny: Hi, John. You never guessed what had happened to me.
John: - What was it? You looked a little upset.
Penny: Oh dear. I had quite a shock.
John: Really! Why
Penny: I was at the zoo, when I heard people shouting and screaming.
John: What on earth was it?
Penny: Everyone was around the fountain and they all looked really scared.
John: Oh my goodness! What was going on? Did someone fall in the water?
Penny: Not someone, but something. There was a long orange snake with black stripes swimming around in it.
John: Oh dear! Was anyone hurt?
Penny: No. The guards caught it quickly and put it back in its cage.
John: Well, well, well. You didn't see that every day, did you?
Penny: No, you certainly didn't.
