Question

Analyze the image above. Which remote sensing technology uses radio waves to observe and predict weather?

A. aerial photography
B. radar
C. GIS
D. GPS

Answer 1

Radar

Step-by-step explanation:

Aerial photography has nothing to do with radio waves, GIS is used for mapping (not weather), and GPS is used to pinpoint location (not used for weather)

Answer 2

'Radar' is the remote sensing technology that uses "radio waves" to "observe and predict" the weather.

Step-by-step explanation:

• The remote sensing technologies that use radio waves to observe and predict the weather are basically 'Weather Surveillance Radars' or 'Doppler Radars'.

• These radars help in locating precipitation with the help of radio waves. These are also equipped to determine the directions of motion of the clouds, the speed and velocity of the clouds and the pouring rain, the type of precipitation (hail, rain, snow), etc.
