AST3033 Amanda Ferencz February 5 th , 2008 Remedial for Unit 1 Test 1. Give the three conditions needed for a TOTAL solar eclipse. Answer : The three conditions for a total solar eclipse include having a new moon, the Sun crossing the orbit at one of the moon’s two nodes, and the moon must cross the ecliptic of the same node as the Sun. 2.

Neap tides occur frequently throughout the day and are less extreme. They relate to the lunar eclipses due to spring tides occurring during new and full moons. During perigee, the Sun’s tidal forces are reinforced by the Moon’s tidal forces, which cause spring tides.
