state the relative positive positions of the sun, moon and the earth during Alina eclipse.
Answers
Answer:
New Moon: Earth, Moon and Sun lined up with the Moon coming between the Earth and the Sun. But usually the alignment is not perfect with the Moon's longitude lying a few degrees above or below the Sun's longitude. The Earth-Moon line and the Earth-Sun line are close to zero degree. However, occasionally the alignment could be near perfect leading to an eclipsing of Sun by the Moon. That is solar eclipse . Not every New Moon is a Solar Eclipse but every Solar Eclipse will coincide with New Moon. On New Moon days Moon rises along with the Sun.
[2] First Quarter: When the Earth-Moon line is
90
o
away from the Earth-Sun line, it is the First Quarter phase. On those days Moon rises (approximately)
6
hours after the Sun rise and exactly one quarter of the Moon's surface is visible from Earth.
[3] Full Moon: Moon, Earth and Sun lined up with the Earth coming between the Moon and the Sun. But usually the alignment is not perfect with the Moon's longitude lying a little above or below the Sun's longitude. The Earth-Moon line and the Earth-Sun line are close to
180
o
away. However, occasionally the alignment could be near perfect leading to an eclipsing of Moon by the Earth. That is Lunar Eclipse . Not every Full Moon is a Lunar Eclipse but every Full Moon coincides with a Full Moon. On Full Moon days Moon rises just as the Sun sets.
[4] Third Quarter: When the Earth-Moon line is
270
o
away from the Earth-Sun line, it is the Third Quarter phase. On these days Moon rises (approximately) 18 hours after the Sun rise or (approximately)
6
hours after the Sun set and again exactly one quarter of the Moon's surface is visible from Earth.
