An atmometer is used to measure
- AWind speed
- BAtmospheric pressure
- CEvaporation rateCorrect
- DSolar radiation
Solution
Concept
Measuring evaporation rate using atmometer
Formula
NONE
Step-by-step solution
1. An instrument used in meteorological and hydrological studies measures specific environmental parameters. Answer: C
Explanation
An atmometer, also known as an evaporimeter, is an instrument specifically designed to measure the rate of water evaporation into the atmosphere. It operates by measuring water loss from a wet porous surface over time. Therefore, option C correctly identifies its primary function.
Why the other options are wrong
A) Wind speed is measured using an anemometer. B) Atmospheric pressure is measured using a barometer.
Shortcut
Atmometer = Evaporation meter ("Atmo" = evaporation to atmosphere).
Common mistake
Confusing an atmometer with a barometer or anemometer and selecting option A or B instead of recognizing its use for measuring evaporation rate.
Correct answer: C) Evaporation rate
