How long does it take for the moon to go around the earth
27 days
What's the difference between a Lunar and Solar eclipse
Solar eclipses occur when the Moon passes between Earth and the Sun, leaving a moving region of shadow on Earth's surface. Lunar eclipses occur when Earth passes between the Sun and the Moon, casting a shadow on the Moon.
What are tides? ..
very long-period waves that move through the ocean in response to the forces exerted by the moon and sun
what are low tides
when the water retreats to its lowest level, moving away from the shore
what produces spring tides
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides—both commonly called spring tides.
how many moons can fit into a earth
50
How long will the eclipse last?
7 minutes 31 seconds
What causes tides?
the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun
how are low tides formed
When the lowest point, or the trough, reaches a coast, the coast experiences a low tide
what is a spring tide
A perigean spring tide, also known as a proxigean spring tide, is a tide that occurs three or four times per year when a perigee coincides with a spring tide.
91 Days
Do I still need to protect my eyes if I’m in an area that’s only getting a partial eclipse?
even those in the path of totality should also use eye protection during the hour-long partial eclipse that precedes and follows totality.
Does the Sun or the moon have greater influence on the tides on Earth
the sun's gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth.
why are some low tides lower than others
As the Earth turns, a region gets closer to or further from the bulges. The further it is from one, the lower the tide.
what is a neap tide
A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.
the moon's orbit around Earth lies in a slightly different plane than Earth's orbit around the sun
How far ahead can tides be predicted?
up to 2 years
What conditions create a low tide?
The moon's gravitational pull generates something called the tidal force
when do neap tides occur
during the first and third quarter moon,
708.7 hour
Why don't we have a lunar eclipse every month
the Moon's orbit is tilted five degrees from Earth's orbit around the Sun,
the other planets, since they have a gravitational pull of their own, also have a small effect on the tides.
how often do low tides occur
what is the difference between neap and spring tides
Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.
