What is the primary function of remote sensors on satellites?
What is the primary function of remote sensors on satellites?
- To provide real-time video footage of Earth for entertainment purposes.
- To capture radiation from the Earth's surface across different atmospheric windows. (correct)
- To transmit communication signals between ground stations.
- To deflect solar flares and protect the satellite's internal components.
How do satellites utilize 'atmospheric windows'?
How do satellites utilize 'atmospheric windows'?
- They help regulate the temperature inside the satellite.
- They allow satellites to communicate with each other more efficiently.
- They enable satellites to 'see' things that are not visible to the naked eye by allowing radiation to pass through the atmosphere. (correct)
- They use them as shields against meteoroids.
Which of the following best describes the role of satellites in observing our planet?
Which of the following best describes the role of satellites in observing our planet?
- They mainly support global communication networks by relaying signals.
- They are advanced tools for observing and collecting data related to Earth's processes and phenomena. (correct)
- They are used exclusively for military surveillance and reconnaissance.
- They serve primarily for navigation, such as providing GPS data.

Flashcards
What do Satellites do?
What do Satellites do?
Satellites use remote sensors to collect data about Earth, including invisible things like heat and moisture, useful for monitoring natural disasters and weather patterns.
How do satellite sensors work?
How do satellite sensors work?
Satellites use remote sensors to capture radiation from the Earth's surface through 'atmospheric windows,' allowing them to 'see' things invisible to the naked eye.
Study Notes
- Satellites act as high-tech gadgets orbiting Earth, equipped with remote sensors.
- They collect various data about the planet, from natural disasters to weather patterns.
- Satellites use remote sensors to capture radiation from the Earth’s surface across different "atmospheric windows".
- Atmospheric windows are special zones where the Earth’s atmosphere is like clear glass.
- This enables satellites to "see" things that are imperceptible to the naked eye or a regular camera.
