A standard rain gauge is a meteorological instrument consisting of a collector of what shape connected to a measuring tube that is used to measure rainfall per unit area at a given time?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Funnel-shaped.
A standard rain gauge is a meteorological instrument used to measure rainfall per unit area over a specific period. It consists of a funnel-shaped collector that captures rainwater and directs it into a measuring tube marked with a calibrated scale. The funnel shape ensures that all rainfall falling into the collector is efficiently guided into the tube for accurate measurement. This simple yet effective design is widely used in weather stations to monitor precipitation and study climate patterns.
