What is the reason for having leap year every 4 years?
A year is not 365 days, but 365.25 days. This means that every four years another day has been created, so to keep the calendar in line with the sun then it must be altered.
What is the line between the light and dark parts of the moon?
It's the line where part of the moon doesn't light the night. and, if you look, that line serves a purpose of telling what kind of moon night it is without looking at a calendar.
What is the astronomical ice line?
The frost line, also known as the snow line or ice line, refers to a particular distance in the solar nebula from the protosun where it is cold enough for hydrogen compounds such as water, ammonia, and methane to condense into solid ice grains.It would have existed between the orbits or Mars and Jupiter.The frost line therefore separates terrestrial planets from jovian planets.See link for more information.
What is precession and What are some of its possible consequences?
'Precession' might be described as 'axial wobbling'. If we think of the Earth's North and South Poles, they lie on a line directly through the centre of the Earth. This line is angled at 23.5 degrees to the orbital plane. As a result it gives us the seasons. However, this line that is tilted at 23.5 degrees is NOT a static angle, but varies over thousands of years. Currently it is decreasing , and will eventually reach an angle of approximately 20 degrees (the seasons will be less extreme). Whereupon, it will then start to increase again to about 30 degrees (the seasons will become more extreme) . This tilting movement is called precession. As an experiment, if you have a child's spinning top or a gyro, set it spinning. You will notice that it 'wobbles', this is precession. The Earth does exactly the same, over thousands of years.
How often do all the planets line up?
The planets line up about every 10,000 years.
What problems would arise if the calendar year were to drift out of line with the astronomical year?
That's exactly what was dealt with in the 16th century. Seasons were starting around the 11th instead of the 21st. Anything that's celebrated with a certain annual change in the weather will not jive with the calendar.
What is the difference between a calendar and a timeline?
A calendar generally is only for 12 months and shows holidays and particular dates you add events. A timeline shows a line of events and can go for years.

Why does the month February get 29 days instead 28 days once in 4 years Geography?
To keep the calendar in line with the rotation of the earth.
How is the Julius Caesar calendar different from ours?
The Julian calendar introduced by Julius Caesar had 365 days per year and 366 EVERY 4 years. This had allowed the calendar to creep out of line with the seasons. The Gregorian calendar we use now has the leap year rule: Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100; the centurial years that are exactly divisible by 400 are still leap years. For example, the year 1900 was not a leap year; the year 2000 was a leap year.
What is the line that divides the calendar days?
The international date line in the Pacific Ocean.
The transition line for calendar days?
international dateline
Where do leap years come from?
The need to keep the year of the calendar in line with the actual position of the Earth in relation to the sun. A year is roughly 365 and a quarter days therefore if unchecked the calendar will lapse and will end up getting behind the seasons.
When you cross the international date line from west to east what do you set your calendar to?
When crossing the line from west to east, you take the last page that you tore off of your calendar, and you glue it back on.
What is the name for the hypothetical line designated as the place where each calendar day begins?
The hypothetical line where each calendar day begins is called the dateline. It is approximately along the 180 meridian.
What is drift in hplc?
Unstbilized column will deviate baseline as little as possible from a horizontal line
What is the line on Earth where the calendar day changes when you cross it?
The International dateline.
