Let’s go step by step to match each weather instrument with what it does.
1.
Thermometer – You’ve probably seen this one! It tells you how hot or cold it is outside. So, it measures air temperature → that matches with
c.
2.
Hygrometer – This one sounds tricky, but “hydro” means water. It measures how much water vapor (moisture) is in the air — that’s humidity → so it matches with
a.
3.
Anemometer – Think of those spinning cups on top of weather stations. They spin faster when the wind blows harder. So, it measures wind speed → that’s
f.
4.
Barometer – This helps predict storms or fair weather by measuring air pressure. High pressure = good weather, low pressure = maybe rain or storm → so it matches with
b.
5.
Wind vane – Also called a weather vane. It has an arrow that points where the wind is coming from. So, it shows wind direction → that’s
e.
6.
Rain gauge – Simple! It catches rain and tells you how many inches or millimeters fell → so it matches with
d.
7. The picture shows a red device with three cups that spin — that’s an
anemometer.
How it works: When the wind blows, it pushes the cups and makes them spin. The faster the wind, the faster they spin. A meter inside counts how fast they’re turning and turns that into a wind speed number (like miles per hour or kilometers per hour).

Final Answer:
1. c
2. a
3. f
4. b
5. e
6. d
7. Anemometer – It has cups that spin when the wind blows. The faster the wind, the faster the cups spin. A sensor inside measures how fast they’re spinning and converts that into wind speed.
