...causing a greater combined (Sun and Moon) gravitational pull...
Hate to break in, here. But, really???
The gravitational attractive force of the Sun as far as its effects on what happens on the Earth's surface is miniscule
!!! And, it is NOT
multiplied just because the Moon is "in line" between the Sun and the Earth!
I mean, check this out --- the Earth and Sun meet up every 24 hours, correct? I mean, the Earth turns...Sun 'appears' in the sky, passes overhead
(from our point of view) every 24 hours. Right???
Angle of Sun in sky changes, depending on your latitude. At the Equator, hardly any change....right???
SO...big dealio...Moon shows up (as it does ALL the time) and happens to (from a certain point of view) cross in front of the Sun, causing a shadow on
the Earth's surface (which, BTW, isn't even as big as the actual Moon, because of the distance).
...A solar eclipse occurs when the moon passes between the Sun and the Earth so that the Sun is fully or partially covered. This can only happen
during a new moon, when the Sun and Moon are in conjunction as seen from the Earth. At least two and up to five solar eclipses can occur each year on
Earth, with between zero and two of them being total eclipses. Total solar eclipses are nevertheless rare at any location because during each
eclipse totality exists only along a narrow corridor in the relatively tiny area of the Moon's umbra.
A total solar eclipse is a spectacular natural phenomenon and many people travel to remote locations to observe one. The 1999 total eclipse in Europe
helped to increase public awareness of the phenomenon, as illustrated by the number of journeys made specifically to witness the 2005 annular eclipse
and the 2006 total eclipse. The most recent solar eclipse occurred on January 26, 2009, and was an annular eclipse. On July 22 2009, the next total
solar eclipse will occur....
Here's the not-to-scale representation...note how the shadow narrows, as it travels from the Moon to the Earth:
Sorry...wasn't trying to scare-monger anyone....just like to use science as a tool of knowledge, not fear...
