Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Remote sensing technology cannot provide data about the Earth's surface in real time. It can only provide data about the Earth's surface that was collected at a specific point in time.

Multiple choice

What are the three main types of remote sensing systems?

  1. Active, passive, and semi-active

  2. Optical, radar, and thermal

  3. Aircraft, satellite, and ground-based

  4. Data collection, data processing, and data display
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The three main types of remote sensing systems are active, passive, and semi-active. Active systems emit their own energy, while passive systems detect energy that is reflected or emitted by the Earth's surface. Semi-active systems emit energy, but they also detect energy that is reflected or emitted by the Earth's surface.

Multiple choice

Which of the following is an example of an active remote sensing system?

  1. Optical sensor

  2. Radar sensor

  3. Lidar sensor

  4. Thermal sensor
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Radar sensors are an example of an active remote sensing system. They emit their own energy, which is reflected by the Earth's surface and detected by the sensor.
