What reference lines are used to locate points on earth?
Latitude and Longitude
The line on surface of earth joining the points where h has same value is what?
The answer depends on what h is supposed to represent.
What is the difference between a 4-digit reference and a 6 digit reference?
To locate points on the Earth's surface, we can use either rectangular coordinate system or geographic coordinate system.4digit or 6 digit reference systems are under rectangular ( projected) system.Their difference lies in assigning Easting and Northing. 4 digit RS uses 2 Easting numbers and 2Northing numbers to show the location of points where as 6 digit uses 3 Easting and 3 Northing numbers. If there is any Hesitation please Well come.
The set of all points collinear to two points is a?
By definition, the word "collinear" means that the points lie in a LINE. The precise manner of line you are talking about depends upon the geometric frame of reference you are using. For example, in Euclidean geometry a line defined by two points is usually taken to be "straight" like the intersection of two planes; but in Global geometry such as the reality of the Earth's surface, a line defined by two points is curved. If you fly from New York to Tokyo, your line of flight is nearly a semicircle; we do not have the technology to travel "straight" from New York to Tokyo through the Earth's core.
How is an exact position in space identified?
There are several methods.You need a reference point (the origin. For an n-dimensional space you will need a set of n axes and n measures which define the position with regard to origin. The axes need not be orthogonal (at right angles) as can be seen from isometric graph paper. The measures need not all be distances, they can comprise one distance and the remainder being angles.Alternatively, you can have many reference points and directions from these reference points to the position. This is the system used by early cartographers for making maps before satellite mapping became possible. The reference points were called triangulation points, and as they moved across the region being mapped, they identified new triangulation points (whose positions they had worked out) so that they had these reference points reasonably near the position to be identified.Yet another method was to have a set of reference points and distances from these reference points to the position. This is the system used for GPS where the reference points are 3 or more satellites and the measures are distances to the position. Actually, the measures are of time but given the speed of light in the Earth's atmosphere, converting time to distance is trivial. A lot of trigonometry follows.
What are the two basic points of reference on the surface of the earth?
which are two basic point of reference on the surface of the earth
What are reference points on the earths surface?
We have several reference points on the Earth's surface, for our convenience. The North and South Poles are a couple. The choice of Greenwich as the zero longitude, and of the International Date Line are another two. These points have no specific feature on the surface, they are decided on for the convenience of the users.

Is potential energy on the surface of earth is always zero?
That depends on what reference level you have chosen. If the (arbitrary) reference level you chose is Earth's surface, then anything on the Earth's surface has zero potential energy. If you choose some higher reference level, an object on Earth's surface has a negative potential energy. If you choose a lower reference level, an object on Earth's surface would have a positive potential energy.
What are the points where the Earth's axis passes through the Earth's surface?
They are the poles.
For determining motion the surface of earth is a common?
reference point
What are two reference points on earth?
They are North Pole and South Pole
What reference lines are used to locate points on earth?
Latitude and Longitude
What is the traveling distance from earth's surface to earth's orbit?
The Earth's center, or a point very close to it inside the Earth, is exactly following the orbit. So there are always two points on the surface that are exactly on the orbit. It seems to me that these points would have to be in the Tropics, and would have to move along the surface as the Earth turns. It's not possible for ANY point on the surface to ever be more than about 6,200 miles from one of these points where the orbit actually meets the surface.
What is the potential on the surface of the earth?
There is no absolute measure for potential energy. The calculation for potential energy depends on the chosen reference level. Quite often, the Earth's surface is chosen as the reference level - in this case, an object on the surface will have zero potential energy.
What are the charateristics of the regions?
A system to locate points on the earth's surface.
What does a grid mean?
A system to locate points on the Earth's surface
