How could the altitude and azimuth be important?
There are a number of ways to describe locations or positions. One of these is to describe the direction toward an object in degrees; this is the "azimuth". For objects in the sky, we must also know the angular elevation above the horizon, or "altitude angle". This is usually shortened to "altitude". By specifying the azimuth angle and altitude angle, we can describe precisely the direction of any object in the sky.
Where would the earth be located in a model of celestial sphere?
The celestial sphere has the Earth at the centre and all the objects in the sky situated on the sphere at infinite distance. Positions of the objects are described by two coordinates, which could be azimuth and elevation, or, in geocentric coordinates, declination and hour-angle.
What direction do objects moving in the Southern Hemisphere curve?
To the north.
Why do christians use objects to worship?
Some Christians use objects like crosses, rosaries, or icons as aids to focus their prayers and devotion. These objects serve as reminders of their faith and help them to connect with God in a physical and tangible way. The objects themselves are not worshipped, but rather used as tools for spiritual reflection and expression.
What does the Coriolus effect do?
It deflects wind and other objects. In the Northern Hemishpere it deflects obfects to the right, and in the Southern Hemisphere it deflects objects to the left.
What are azimuth and altitude to describe?
Azimuth is the angle, typically using true north as zero degrees to an object from viewers location. An altitude (if expressed as an elevation angle from the viewer) provides a line of sight to an object in space. If you were standing at a point and facing true north and there was an airplane flying at 20,000 ft and you knew the elevation angle you could compute the range and have an (X,Y,Z) location for the object.

What is the coriolist effect?
The Coriolis effect is the appearance of objects to change direction when they are viewed in a rotating field. As the Earth is constantly rotating, this causes moving objects to move clockwise in the Northern Hemisphere and counterclockwise in the Southern.
What is a parallel and a meridian?
They are imaginary lines that create a system of coordinates on the surface of the Earth (other spherical objects). The parallels (or latitudes) measure the angular distance from the equator which is the line that is in the plane perpendicular to the Earth's axis of rotation. The North Pole is 90 degrees to the North of the equator and the South Pole is 90 degrees South.The Meridians (or longitude) run from Pole to Pole. The one going through Greenwich - in London and home of the Royal Observatory) is designated the Prime Meridian. Other meridians measure the angular distance from the Prime Meridian in the Eastward or Westward direction. There are 180 degrees to the East of the Greenwich Meridian and 180 to the West. Actually, that is not strictly true because 180 E and 180 W are the same meridian on the opposite side of the Earth from Greenwich. That meridian forms much of the International Date Line.
What is the azimuth and altitude of the star procyon?
The azimuth and altitude of any celestial body depend on the precise time and date, and on the observer's location.I live in a suburb of Sacramento, CA, and the time right now is May 7, 2011 at 4:31PM Pacific Daylight Time. Procyon is, at this moment, at an altitude of 52 degrees 36 minutes, and an azimuth of 149 degrees 18 minutes; a little east of south. It is at a distance of 11.41 light years. Like most celestial objects, it tracks to the west at about 4 degrees per minute.I get this data from the free planetarium program Stellarium, available at stellarium.org. If you download this program and program it with your exact location, you can get up-to-the-second calculations for yourself.However, we don't generally refer to stars by azimuth and elevation; instead, we use the more common measurements of Right Ascension and Declination, numbers that do not change measurably over the span of a century. According to Wikipedia, Procyon is at:Right ascension07h 39m 18.1/17.7sDeclination+05° 13' 29/20"

What was Pluto unable to do to it's neighbor planets?
Pluto has not been able to pull any neighboring planets or space objects into rotation around it or, it has not "cleared" it's rotational path as Saturn crosses over Pluto's path every so many years.
