The physical systems of the earth include the lithosphere, the hydrosphere, the atmosphere and the biosphere.
The hydrosphere consists of the earth's water. Approximately 70% of the earth's surface is water. It is found in oceans, lakes, rivers ponds, ice and ground water.
The Lithosphere consists of the solid surface that covers the Earth. Features such as hills, mountains, plateaus, plains and ocean basins are land forms covering the lithosphere.
The atmosphere consists of the thin layer of gases that surround the earth and rises up to 100 miles from the earth's surface, beyond which is outer space.
The biosphere consists of all things living on the surface of the earth and includes animals and plants.

Explanation:
GIS stands for Geographic Information System.
GIS is a computer system that is used to record information on to maps.
Five key components of GIS are as follows:
1. Hardware
2. Software
3. Data
4. People
5. Methods.
GIS is based on at least two important areas of technology: gathering digital spatial data and creating digital maps.
Latitude refers to vertical radial distance from the equator, and longitude refers to horizontal radial distance from the prime meridian whose location was decided arbitrarily. It is a pair of degree measures which goes up to 90 degrees, dictating how many degrees an object is from one of the two lines.
