Two-dimensional is a flat surface. It has two dimensions: height and width. Three-dimensional can be measured height, width and depth.For instance a sculpture, a relief, etc.
Height above earths surface is called elevation
Altitude. Height. Depends on what you are measuring.
Elevation
Yes it is.

Those letters will spell the word elevation.
In water or other liquids the wave travels across the surface as a difference in height and with a certain period or wavelength.
One factor is the height of the ramp. The higher the height of the ramp the further the car travels. Another factor is the surface of the ramp. With a rough surface on the ramp e.g sand paper the car travels a short distance. With a lubricated surface on the ramp e.g Vaseline the car will travel a very long distance.
The lowest is the troposphere, which is the layer that provides most of our weather. It contains about 80% of the Earth's air, but extends only to a height of about 11 miles (17 kilometers) at the Equator and less at the Poles.
