State two differences between the artificial satellites of the Earth and its natural satellite Moon.
Natural satellites are formed by nature. Moon is the natural satellite of the Earth. Following are the differences between the Moon and the artificial satellites of the Earth:
1. Moon is the natural satellite of the Earth and is formed by nature. It is permanent.
1. Artificial satellites are manmade and are launched from the Earth. For example, INSAT, IRS, Kalpana-1, EDUSAT are artificial satellites.
2. The distance between the moon and the Earth is very large and hence, it does not have any practical application.
2. They revolve around the Earth much closer than earth’s natural satellite, the moon. They have many practical applications. They are used for forecasting weather, transmitting television and radio signals. They are also used for telecommunication and remote sensing.
