Matching Weather Elements with Instruments
This question requires matching specific weather elements with the instruments used to measure them. Let's break down each pair:
Temperature Measurement
Temperature, which is the degree of hotness or coldness of the atmosphere, is measured using a Thermometer. A thermometer works based on the principle of thermal expansion, where substances like mercury or alcohol expand when heated and contract when cooled.
Therefore, the correct match for Temperature is (IV) Thermometer.
Rainfall Measurement
Rainfall, the amount of precipitation that falls over an area, is measured using a Rain gauge. A rain gauge typically consists of a container that collects rainwater, allowing for the measurement of its depth over a specific period.
Thus, the correct match for Rainfall is (III) Rain gauge.
Wind Velocity Measurement
Wind velocity, which refers to the speed and direction of air movement, is measured using an Anemometer. Commonly, cup anemometers are used to measure wind speed.
So, the correct match for Wind velocity is (II) Anemometer.
Dew Measurement
Dew, which is water vapor from the air that condenses onto cool surfaces, can be measured or observed using a Dew gauge. A dew gauge helps quantify the amount of dew deposition.
Consequently, the correct match for Dew is (I) Dew gauge.
Summary of Matches
Based on the analysis, the correct pairings are:
| List-I (Weather Element) | List-II (Instrument) | Match |
|---|---|---|
| (A) Temperature | (IV) Thermometer | (A) - (IV) |
| (B) Rainfall | (III) Rain gauge | (B) - (III) |
| (C) Wind velocity | (II) Anemometer | (C) - (II) |
| (D) Dew | (I) Dew gauge | (D) - (I) |
The correct option that represents these matches is (A) - (IV), (B) - (III), (C) - (II), (D) - (I).
