Reply #22: and the tropics (Cancer & Capricorn) would extend further from the equator [View All]

The OP could probably get some bonus points by taking a map of the Earth and redrawing the new lines.

This seems a remarkably dumb phrasing. Declination is the angle of the sun above the horizon, and the question probably is best served by using that measurement taken at noon.

I believe it's the appropriate word. Altitude is the angle of the sun above the horizon. Declination is the angle (north/south) of the celestial equator. To determine the declination, you would need to start by measuring the altitude of the sun at its highest point, i.e. noon.
