Question

When a total solar eclipse occurs, why is a partial eclipse also seen from the earth?

Answer 1

1. On a new moon day, if the sun, the moon, and the earth are in the same plane and fall in one line, the shadow of the moon falls on the earth.
2. A shadow of the moon is of two types. A dark shadow of the moon falls on some areas of the earth and at the same time, a light shadow of the moon falls on some other areas of the earth.
3. A total solar eclipse is visible from the areas of the earth falling in the moon's dark shadow and a partial solar eclipse is visible from the areas of the earth falling in the moon's light shadow. Thus, when a total solar eclipse occurs, a partial eclipse is also seen from the earth.
