Most maps are printed on pieces of paper, so they have 2 dimensions (length and width). So, it is a 2D representation of a 3D entity: the Earth's surface has length, width, and height (more commonly knows as elevation). Topographic maps still have 2 dimensions, but they use topographic contours to represent the third dimension (elevation). You can also get "relief maps" that have lumps and bumps to represent topography. These are commonly are referred to as being "3D", but most geographers would tell you that they are "2.5D". In other words, they are folded 2D surfaces that lack true three-dimensionality.

Two, unless it includes contours then the map is attempting to display 3 dimensions on 2 dimensional map. Most common maps are drawn on a flat 2 dimensional piece of paper which has length and width (which correspond to longitude and latitude). A relief map is actually a three dimensional map because the map actually has real depth (to display altitude). Mountains are actual bumps on the map and valleys and the lakes and oceans are depressions in the map. (Technically it is still a 2 dimensional surface that has been deformed but let's not go into that)

A map has two dimensions. A model of 'map' has three dimensions.

It depends on the map.
You have two dimensions to represent surface measures, then altitude shown by colours, hatching or contour lines. That is three. Then you have weather, population, temperatures and so on that are all dimensions that can be measured and shown on your map.
ther are other maps designed to represent other things beside earth.

atleast 2.
Topigraphical maps sometimes are done in 3 dimensions.
Globes are done in 3 dimensions and are essentially maps.

Generally, two dimensions, latitude and longitude. Altitude is sometimes shown on topological maps which would make it three dimensions.

2 to 3, I guess; but, a lot more if you include dimensions for water and all of the other concepts presented.

the physical paper has 3, while the map itself has 2 to 3 depending upon if it topographical or not.
