Question 4 • AZ-Earth and Space Science B

Global Precipitation Measurement (GPM) is a tool scientists use to forecast weather. Which statements describe GPM? Select three options.

Answer
A
It is a computer model used to predict weather.
B
It is a satellite that collects data about rain and snow.
C
Its orbit covers 90 percent of Earth’s surface.
D
Its orbit covers 70 percent of Earth’s surface.
E
The sensors measure visible light.
F
The sensors measure microwaves.

Explanation

GPM is a satellite mission that collects information about precipitation, including rain and snow. Its orbit reaches from about 65° north to 65° south, covering roughly 90 percent of Earth’s surface. Its instruments measure microwaves, which help detect precipitation; GPM is not a computer model, and its sensors are not described as measuring visible light.
