Q

Explain why total solar eclipses are much less frequent than partial eclipses?

A

The moon’s orbit is not always in line with the orbit of the Earth around the sun.
In fact it is tilted at about a 5 degrees to the Earth’s path around the sun.
The dark part of the shadow of the moon does not usually fall on the Earth.
However, the partial shadow is larger and more likely to fall on part of the Earth.
