Signals intelligence satellites can operate either in low Earth orbit or in extremely high, geosynchronous orbit, where they appear to stay in one spot in the sky. These satellites listen for communications from cellular telephones, walkietalkies, microwave transmissions, radios, and radar. They relay this information to the ground, where it is processed for various purposes.

to the earth is so high, very little fault current returns to the power supply if the earth is the only fault current return path. Result—the circuit overcurrent device won't open and all metal parts associated with the electrical installation, metal piping, and structural building steel will .
Remote sensing benefits. Remote sensing is a valuable tool in mineral exploration, thanks to its ability to save time and money while providing helpful information. It is best used for the discovery of highvalue commodities such as diamonds and gold, which are becoming more difficult to locate.
Geophysical techniques used for petroleum exploration utilize equipment to measure such things as: electrical currents, gravitational and magnetic anomalies, heat flow, geochemical relationships, and density variations from deep within the earth.
Geological science and associated technology are used to find and evaluate the coal resources that will be used to meet these needs, a process referred to as coal exploration, and to assist in designing and operating effective systems for coal mining (coal mining geology), preparation and utilization tasks.

Exploration for natural gas typically begins with geologists examining the surface structure of the earth, and determining areas where it is geologically likely that petroleum or gas deposits might exist. It was discovered in the mid 1800s that 'anticlinal slopes' had a particularly increased chance of containing petroleum or gas deposits.
