A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.

Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, usually at ordered pair.

The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axis, expressed as signed distances from the origin.

The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic system, vertical datum).

Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy.

Most weather phenomena occur in the lowest level of the atmosphere, the troposphere, just below the stratosphere.

Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time.

When used without qualification, "weather" is generally understood to mean the weather of Earth.

Climate is the statistics of weather, usually over a 30-year interval.

It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time.

Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region.
