how are the moon, earth,sun placed with respect each other?
Answers
Answer:
As the Earth rotates on its axis and revolves around the Sun, day and night and seasons result.
When the new moon comes between the Earth and the Sun along the ecliptic, a solar eclipse is produced.
When the Earth comes between the full moon and the Sun along the ecliptic, a lunar eclipse occurs.
Observing the Moon from Earth, there is a sequence of phases as the side facing us goes from completely darkened to completely illuminated and back again every 29.5 days.
As the Moon orbits Earth, tides align with its gravitational pull.
The Sun produces a smaller tide. When the solar and lunar tides align, at new and full moons, higher than normal tidal ranges called spring tides occur.
At first and last quarter moons, the solar tide and lunar tide interfere with each other, producing lower than normal tidal ranges called neap tides.
