What is the current age of the earth?
The earth is roughly 4.5 billion years old. We know this to be the case because we have dated rocks from the moon that old, and earth must be at least as old as our moon.
What do the earths moon name mean?
The name "moon" comes from Old English "mōna," which is derived from the Proto-Germanic word "mēnô." The word "moon" likely has roots in ancient Indo-European languages, where it referred to the celestial body that orbits Earth.
How are moon rocks used to determine the age of the Earth?
The oldest moon rocks are actually older than the oldest Earth rocks. The moon formed from accreted material that resulted from a collision between Earth and a Mars sized protoplanet. Both the Earth and the moon were molten for a period after the collision. Because of the moon's smaller size, it's surface cooled very quickly compared to the Earth. The solidified magma (rock) that formed the moon's crust has been dated at roughly 4.4 billion years of age. Even though no Earth rock has been found to date this old, we can still reasonably assume that the Earth is at least that old due to the fact that the moon is formed from accreted material from the previously mentioned collision.
What is the length of years does earth have?
A year on Earth is about 365.24 days long. Most years are 365 days, and leap years have 366 days.
How many days left till summer?
The Earth is about 4.5 billion years ols and probably has some 5 billion years to go before the sun consumes it. Using the present rotation speed to estimate "days" this would be about 2 trillion days (2x1012 days) This is about 600 million lifetimes.
What two words are from Old English that have to do with the moon?
The two Old English words related to the moon are "mōna," which directly translates to "moon," and "mōnað," meaning "month." The term "mōnað" is derived from the lunar cycle, as months were traditionally based on the phases of the moon.
What are the names of the phases of the moon during a solar eclipse?

The sun is ahead of the moon in the sky during waxing phases what time would a 10 old moon set if the sun set at 7pm?
The Moon sets about 50 minutes later each day. At the "new moon", the Moon and Sun are very close together in the sky, and rise and set together. 10 days later, the Moon rises (and sets) about 8 hours after the Sun does. So the Moon 10 days after the new would be waxing gibbous, and would set around 3 AM.
How do Sioux Indians view time?
In the old days, I think Indians tribes measured time by the daily appearance of the moon in the sky (I'll be seeing you Tonto in 3 moons) and by phases of the moon (quarter, half, three-quarters and full), plus seasonal moon (such as harvest moon) and position in the sky. Frankly, I don't know whether the Sioux used the moon and/or the sun.

What are the origins of the word month?
Before modern calendars, people used to keep track of the days by watching the phases of the moon. One full cycle of the moon's phases is approximately 28 days, which is very close to the amount of time we now know as one month.
Does the moon move in a regular pattern from night to night?
Yes it does, a pattern that repeats. Starting with new moon, when we see nothing, the moon seems to get bigger from night to night as the angle between Sun, Moon and Earth changes. The phases are named differently by different people but may be called new moon, new crescent, half moon, waxing gibbous, full moon, waning gibbous, old half moon, old crescent, then new moon again. The cycle takes about 29.53 days on average.

What are the superstitious beliefs in agricultural practices?
The moon and its phases and placement play a major role in many agricultural superstitions. Planting and harvesting are commonly done at the new and full moon respectively. The house or placement of the moon can help determine what type of crop you should be planting. Animals should be slaughtered according to the moon`s phases. Preserving meats (smoking and brining) last better in certain phases of the moon. Young animals tend to wean better in a waning moon. If you need to geld an animal, or crop its horns, or shear its coat, there are phases and houses of the moon that are more auspicious than others. Many of these things can be found in the Old Farmers`Almanac, and you might be surprised at the number of farmers that still go by them.
What is waxing in the moon phases?
It is when the moon is more than half full and getting larger. So it is any stage between half full and full.
How can one effectively compare moon phases?
To effectively compare moon phases, one can observe the shape and position of the moon in the sky at different times. By noting the changes in the moon's appearance over a period of time, one can track the progression of moon phases from new moon to full moon and back again. Additionally, using a lunar calendar or moon phase chart can help in identifying and comparing the different phases of the moon.
