Why are certain constellations put on the circumpolar constellation chart and other are on the equatorial constellation chart?

because the circumpolar constellations are visible all year long and the others are not.

What are some seasonal constellations?
Most constellations are seasonal, meaning they appear in the sky during reasonable evening hours only at certain times of the year. For example, Orion is a popular winter constellation. Only circumpolar constellations are not seasonal.
How do a constellation act like an address?
if you study constellations you know where certain constellations are around the world such as in the southern hemisphere
What is the most seen constellation?
Any of the circumpolar constellations. Most common: The Big Dipper (Ursa Major), Cassiopea, Cepheus, the Little Dipper (Ursa Minor). This is because these constllations can be seen year-round, and others only appear in certain seasons. (i.e. Orion constellation can only be seen in the night sky during winter.)
Why is there a constellation?
So the earlier astronomers can locate things in the sky.. They used the constellations to help them point out certain things
Are constellations only visible in certain seasons due to the revolution of the Earth toward the constellation?
It is only partly true. Stars have latitude and longitude just as we do on Earth, but they are called Declination and Right Ascension. A star that has a declination greater than 90 minus your latitude will never set. Such stars are called circumpolar stars. I live at 35° south so stars with declination 90-35=55° will never set. For example I can always see the Southern Cross.

Explain why the big dipper and the little dipper are not separate constellations?
Quite simply, this is the way constellations are defined. Constellations are arbitrary groupings of stars; somebody considered that a certain group of stars looks like a bear, and called it "big bear". This is one of the 88 official constellations recognized by modern Astronomy; you can look for other images in the stars, i.e., groups of stars. Those groups might be part of a constellation, or they may span more than one constellation. The Big Dipper happens to be part of a larger "official" constellation: the Big Bear (Ursa Major).Quite simply, this is the way constellations are defined.

Why do you see different constellations at different times of years?
Because Earth moves, and it appears that the constellation moves. It just seems that we see it at a certain time of year.
How do you see different constellations in the sky at different times of the year?
The relative position (direction, actually) of a constellation and the Sun changes, due to Earth's orbit around the Sun. Thus, at one moment the Sun might be in a certain constellation; half a year later, the Sun will be in a constellation opposite in the sky.
What is constellation what is its astronomical significance?
Constellations consist of stars that make up certain patterns in the night sky. They are significant because they donÃ?t move, and can help you find out where you are on Earth.
Who discovered ursa major the constellation and when?
You don't "discover" a constellation, for the same reason that you don't discover the Sun or the Moon. The stars that make up the constellation are there to see; at some moment, somebody - the ancient Greeks in the case of the "classical" constellations, including Ursa Major - somebody, then, decided that a certain group of stars look this this or that, and gave it a name.
Are constellations only visible in certain seasons due to the revolution of earth toward the constellation?
It is only partly true. Stars have latitude and longitude just as we do on Earth, but they are called Declination and Right Ascension. A star that has a declination greater than 90 minus your latitude will never set. Such stars are called circumpolar stars. I live at 35° south so stars with declination 90-35=55° will never set. For example I can always see the Southern Cross.
