Give uses of a satellite.

1. Communication: Satellites are used for communication purposes, such as transmitting television signals, phone calls, and internet data around the world.

2. Weather forecasting: Satellites are used to monitor weather patterns and gather data that helps meteorologists predict weather conditions.

3. Navigation: Satellites are used for GPS systems that provide accurate location information for various applications, such as driving directions and tracking devices.

4. Earth observation: Satellites are used to monitor and study the Earth's surface, atmosphere, and oceans for various purposes, such as environmental monitoring, disaster response, and urban planning.

5. Scientific research: Satellites are used for various scientific research purposes, such as studying the Earth's climate, mapping the universe, and monitoring natural disasters.

6. Military and defense: Satellites are used for military and defense purposes, such as surveillance, reconnaissance, and communication in remote or hostile environments.

7. Agriculture: Satellites are used in agriculture for monitoring crop health, predicting yields, and optimizing irrigation and fertilization practices.

8. Search and rescue: Satellites are used to locate and rescue individuals in distress, such as lost hikers or shipwreck survivors.

9. Telemedicine: Satellites are used to provide medical services in remote or underserved areas through telemedicine, allowing patients to consult with healthcare professionals from a distance.

10. Education: Satellites are used in educational settings to provide access to remote learning resources, such as online courses and educational programming.
