Exploring Artificial Satellites

What are the two main types of artificial satellites?

• Weather satellites and Navigation satellites

• Military satellites and Space telescopes

• Communication satellites and Earth observation satellites

• Research satellites and Communication relays

Name one function of communication satellites.

• Provide weather data for specific regions.

• Transmit television signals only to local areas.

• Monitor space debris in Earth's orbit.

• Relay signals for global communication.

What type of satellite is used for weather monitoring?

• Communication satellites

• Meteorological satellites

• Navigation satellites

• Spy satellites

How do satellites help in GPS technology?

• Satellites are responsible for creating maps used in GPS navigation.

• Satellites are used to power GPS devices directly.

• Satellites provide signals that enable GPS receivers to determine their precise location through triangulation.

• Satellites only provide internet connectivity for GPS systems.

What is the primary purpose of reconnaissance satellites?

• To gather intelligence and monitor activities on the Earth's surface.

• To provide weather forecasts for agricultural purposes.

• To support space exploration missions and research.

• To facilitate global communication through satellite networks.

Which type of satellite orbits the Earth at a fixed position?

• Polar satellite

• Geostationary satellite

• Low Earth orbit satellite

• Medium Earth orbit satellite

What is the role of satellites in television broadcasting?

• Satellites are used to create television shows.

• Satellites only receive signals from local broadcasters.

• Satellites are primarily for internet connectivity in homes.

• Satellites enable the transmission of television signals over long distances, facilitating broadcasting to remote areas.

How do satellites contribute to scientific research?

• Satellites contribute to scientific research by providing data for climate monitoring, weather forecasting, disaster management, and astronomical observations.

• Satellites are primarily used for communication and entertainment purposes.

• Satellites only provide data for military operations and surveillance.

• Satellites are mainly used for navigation and personal tracking services.

What is the difference between low Earth orbit and geostationary satellites?

• Low Earth orbit satellites are closer to Earth and move relative to the surface, while geostationary satellites remain fixed over one point on Earth.

• Low Earth orbit satellites are stationary above the poles.

• Geostationary satellites orbit at a lower altitude than low Earth orbit satellites.

• Low Earth orbit satellites are used exclusively for communication purposes.

What technology do satellites use to communicate with Earth?

• Optical fibers

• Radio waves

• Infrared signals

• Ultrasound waves
