What causes 2 main types of eclipse?

Answer 1

Two main types of Eclipse????

Solar Eclipse can be Total , Annular or Partial.

Lunar Eclipse can be Total or Partial.

For Solar Eclipse the order, in a straight line, of the astronomic bodies is Sun - Moon - Earth

For Lunar Eclipse the order, in a straight line, of the astronomic bodies is Sun - Earth - Moon..

Then there is consideration for the distance between astronomic bodies.

For Total Solar Eclipse, the Moon is nearest to Earth. Sun completely covered.

For Annular Solar Eclipse, the Moon is furthest away from Earth. A ring of sunlight is seen.

For Partial Solar Eclipse, the Moon only partially crosses the Sun's face.

For a Total Lunar Eclipse, the Earth blocks direct sunlight to the whole of the Moon. A dull red/grey Moon is seen, instead of a bright full Moon.

For a Partial Lunar Eclipse, the Earth blocks direct sunlight to only part of the Moon. A gibbous/crescent Moon is seen, in full light.

Answer 2

A shadow thrown by the Moon (solar eclipse) and a shadow thrown by the Earth (lunar eclipse).
