  1. Question 1

    A weather station recorded air pressure changing from 1022 hPa to 1018 hPa over 24 hours. What does this suggest?

    • A. rain and wind are becoming more likely
    • B. settled, dry weather is becoming more likely

  2. Question 2

    Why does high pressure (an anticyclone) usually bring dry weather?

    • A. Air sinks and warms, so clouds do not form easily
    • B. Air rises and cools
    • C. High pressure blocks sunlight
    • D. High pressure creates rain

  3. Question 3

    Weather systems: which statement is NOT true?

    • A. Meteorologists use satellites and computer models to forecast weather.
    • B. Air pressure is measured with a barometer.
    • C. Isobars on a weather map join places of equal pressure.
    • D. Weather and climate mean the same thing.

  4. Question 4

    A weather station recorded air pressure changing from 1018 hPa to 1008 hPa over 6 hours. What does this suggest?

    • A. rain and wind are becoming more likely

  5. Question 5

    A barometer reading falls steadily over a day. What weather is most likely?

    • A. clouds, wind and rain as low pressure arrives
    • B. snow in summer for certain
    • C. clear, calm sunny skies
    • D. no change at all

  6. Question 6

    Weather systems: which statement is NOT true?

    • A. Closely spaced isobars mean strong winds.
    • B. Meteorologists use satellites and computer models to forecast weather.

    • D. Air has no weight.

  7. Question 7

    A weather station recorded air pressure changing from 1024 hPa to 1014 hPa over 6 hours. What does this suggest?

    • A. rain and wind are becoming more likely

  9. Question 9

    Weather systems: which statement is NOT true?

    • A. Meteorologists use satellites and computer models to forecast weather.
    • B. Weather and climate mean the same thing.
    • C. Closely spaced isobars mean strong winds.
    • D. Air pressure is measured with a barometer.

  10. Question 10

    • B. Isobars on a weather map join places of equal pressure.
    • C. Air pressure is measured with a barometer.
    • D. Closely spaced isobars mean strong winds.

    • A. Fog always forms for days
    • B. Temperatures rise sharply and stay high
    • C. Nothing happens
