   Respuesta: a) The state of the atmosphere in a place at a specific time

   The weather is the state of the atmosphere in a specific place at a specific time. The average over 30 years is the climate.

2. 2 · Instruments

   Match each instrument with what it measures

   One instrument for each element.

   1. Thermometer
   2. Hygrometer
   3. Rain gauge
   4. Anemometer

   • a) Humidity
   • b) Precipitation
   • c) Temperature
   • d) Wind speed
   Ver la solución

   Respuesta: Thermometer → Temperature · Hygrometer → Humidity · Rain gauge → Precipitation · Anemometer → Wind speed

   Thermometer → temperature, hygrometer → humidity, rain gauge → precipitation, anemometer → wind speed.

3. 3 · Wind

   Which instrument shows the direction of the wind?

   You made one in the Hands on.

   • a) An anemometer
   • b) A wind vane
   • c) A thermometer
   • d) A satellite
   Ver la solución

   Respuesta: b) A wind vane

   A wind vane shows where the wind is blowing from. The anemometer measures how fast it blows.

4. 4 · Humidity

   Humidity is the amount of ___ in the air.

   We cannot see it, but we can feel it.

   • a) heat
   • b) water vapour
   • c) dust
   • d) wind
   Ver la solución

   Respuesta: b) water vapour

   Humidity is the amount of water vapour in the air. It is measured in percentage (%).

5. 5 · Units

   Drag the unit for precipitation

   The rain gauge measures it.

   🌧️ Precipitation is measured in ____

   Fichas: millimetres (mm) · degrees Celsius (°C) · percentage (%) · hours

   Ver la solución

   Respuesta: millimetres (mm)

   Precipitation is measured in millimetres. Temperature is in °C and humidity in %.

6. 6 · Clouds

   What are clouds made of?

   They float in the atmosphere.

   • a) Smoke
   • b) Tiny droplets of water or ice crystals
   • c) Cotton
   • d) Carbon dioxide
   Ver la solución

   Respuesta: b) Tiny droplets of water or ice crystals

   Clouds are made of millions of tiny droplets of water or ice crystals.

7. 7 · Clouds

   Drag the missing word

   When water vapour cools down, it…

   water vapour rises → cools → ____ → cloud

   Fichas: condenses · evaporates · melts · burns

   Ver la solución

   Respuesta: condenses

   The water vapour cools and condenses into tiny droplets that make the cloud.

8. 8 · Precipitation

   Small balls of ice fall from the sky. What is it?

   Rain, snow, hail or sleet?

   • a) Rain
   • b) Snow
   • c) Hail
   • d) Sleet
   Ver la solución

   Respuesta: c) Hail

   Hail is small, hard balls of ice. Snow is soft flakes, and sleet is rain and snow mixed.

9. 9 · Forecast

   A person who studies the weather and makes weather maps is…

   They make the weather forecast.

   • a) a climatologist
   • b) a meteorologist
   • c) an astronaut
   • d) a geologist
   Ver la solución

   Respuesta: b) a meteorologist

   Meteorologists study the weather and predict what it will be like in the near future.

10. 10 · Will or may?

    We are not sure, but it is possible: "It ___ rain in the north tomorrow."

    Possible, not certain.

    • a) will
    • b) may
