Rockin Review!

This a diagram of the moon phases. The moon changes phases in a repeating cycle with a total of eight different moon phases!

Below is a picture describing how the moon affects the oceans' tides. For example, when the moon is on the right side of the earth, the high tides are going to be on the left and right sides of earth while the low tides are going to be on the top and bottom of the earth. This is due to the moon's gravitational pull, and the inertia on the side farthest from the moon.

All of this has to due with the lunar cycle. The lunar cycle lasts, on average, 29.53 days. In this cycle there are many different moon phases and different names for each moon phase.

Some include:

- Waxing, the moon at the time after a new moon or before a full moon.

- Waning, the moon after a full moon and before a new moon. Also known as an old moon.

- Gibbous, when the moon is over half full, but also not fully illuminated.

- Crescent, the moon that is part way between a half moon and a new moon.

Understanding What A Moon Phase Is All About

Now, even though when you think moon phases you think lunar cycle, that is really not all the moon phases are about. The whole entire reason that the moon has phases is due to the sun. The sun lights up different parts of the moon so the moon appears to only be a crescent in the sky...

Or half of the moon...

And sometimes, all is well and the moon we have all come to know is full and in its rightful spot...

The sun makes all of these amazing moon phases occur!

This concludes the #RockinReview tackk presentation but i hope that it has assisted your knowledge of the moon and its phases in some shape or form!

Eclipses #eclipses

Copernicus was a man who got a really good understanding of what astronomy was/is and concluded that the earth was not the center of the solar system and that, instead, the sun was.

We have seasons because the earth is tilted as it makes its yearly journey around the sun. The Earth's axis is tilted at an angle of about 23 degrees. This means that the Earth is always "pointing" to one side as it goes around the Sun.

Even though the sun is closer during winter, it is only closer in some areas so the areas it is far away it is cold making it winter. When it is close it can only cover so much of earth. When it is far away it can cover a much larger part of earth.

We don't have lunar eclipses each month because the moon does not travel in the same plane each time.

We have day and night because part of the day the sun is shining on our part of the earth, making it day, and then it starts to move away. When the sun moves away, the moon comes in to take it's place, and i becomes night.

Equinox means the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length.

Solstice means either of the two times in the year, the summer solstice and the winter solstice, when the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days.
