Answer 2

Movement of surface currents

Explanation:

• Remote sensing is used to gather data regarding Land use-mapping, weather forecasting, environmental study, and resource exploration.
• In the case of ocean currents, only satellite remote sensors can determine ocean currents synoptically over coastal regions.
• SAR(Synthetic Aperture Radar) is also used to determine the ocean currents.
• The flow patterns of ocean currents are drafted with satellite infrared scanners.
• Usually, many oceanographers use Radio antenna and high-frequency "Radio detecting and Ranging" for measuring surface ocean currents.
