The term Zoid in geometry use term to refer to "shapes," without definite properties for problems. For example, comparing two groups of shapes and say a "Zoid" is any shape in both groups, then such is the case. It's simply a "nothing," they added an "-oid" in the end to make it sound like a figur.

Any location in space can be described with respect to the surface of the earth: Latitude, Longitude, and Height. 3 parameters, because space is 3 dimensions. There are only 3 directions, and any other direction is actually a sum of multiples of these three directions. That's why there are only 3 dimensions.

Geographers use all sorts of tools to help them investigate their questions. They commonly use maps, globes, atlases, aerial photographs, satellite photographs, information graphics, and a computer program called GIS. Read below to learn about different tools.

Geodesy, the science of measuring the Earth's shape and positions on it, allows the measurement of plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.

Geocoding is the process of taking coded location information (such as addresses or grids) and turning it into explicit location information (X and Y coordinates, usually). ... Georeferencing involves fitting an image to the Earth based on matching up visual features of the image with their known location.

g or G. An acceleration equal to the acceleration of gravity, 980.665 centimeter-second-squared, approximately 32.2 feet per second per second at sea level; used as a unit of stress measurement for bodies undergoing acceleration. See acceleration of gravity; gravity. acceleration of gravity (symbol g)
