Approximately how often do we have an eclipse?
Lunar: every 6 months; Solar: every 6 months, so twice a year..
Why don't we have an eclipse every month at every full and new moon?
Because the moon, sun, and earth are not lined up together for the eclipses to happen
What is the reason for this rise and fall of water?
It is because of the gravitational pull from the sun, moon and earth.
What causes this type of tide to be so high? How often does this happen?
This tide is so high because the gravitational pull of the sun and moon on the earth pull in the same direction, making the tides more intense. Spring tides occur twice a month, every full moon and every new moon.
List the order of the Earth, moon and sun in order from largest to smallest.
c. Moon or (S.E.M)
