The canaries probably better in many ways than Denmark or even Northern beaches.
But consider......
If you had turned 360 degrees looking out to the changing horizon it would always appear at "eye-level" otherwise it would have had to appear to sink/dip below eyelevel --- which it don't!!
If you could get sufficiently high -- miles up--- so that you could see the whole 360deg horizon in one eyeful you would see a curvature. As astonauts do. But they don't SEE a sphere only the disc outline ( as we do the Moon)
.
I should get a life, I know.
All the best Thea
