Trang 1898) Compare and contrast latitude and declination. How does each relate to your position on
Earth?
Answer: Both are measured in degrees north or south of the equator, and are used to find
positions on the Earth or in the sky. If you are at latitude 30 degrees north, then the starsthat pass through your zenith (directly overhead) will have a corresponding declination

Trang 19104) What conditions are necessary for a total solar eclipse?
Answer: The Moon must be at new phase (directly between Earth and the Sun), it must also be
both at the closer distance in its orbit and on the ecliptic (crossing a node). Only people
on those parts of the Earth where the Moonʹs umbral shadow passes will see a totalsolar eclipse
