1. Remote Sensing

2. Remote Sensing
This is the process of collecting data about Earth far above Earth’s surface
Satellites detect different wavelengths of energy reflected or emitted from Earth’s surface
This is electromagnetic radiation

3. Landsat Satellites
This receives reflected wavelengths of energy emitted by the earth’s surface
The images show up in different colors depending upon the warmth of the feature

5. Topex/Poseidon Satellite
Use a radar to show features on the ocean floor
Uses high frequency signals that are transmitted from the satellite to the surface of the ocean

6. The Global Positioning System
This is a radio-navigation system of at least 24 satellites that allow its users to determine their exact location on Earth
The satellites can determine the exact latitude and longitude of the person

7. Sea Beam
This is also used to map the ocean floor except it is located on a ship
Sea beam uses sonar, the use of sound beams
