Sure! Below are the answers to the questions based on the diagram:
1.2.1 The lines in the sketch showing places of equal pressure are known as **isobars**.
1.2.2 The high pressure is represented by **5280** hectopascals.
1.2.3 **Pressure gradient** force determines the speed of the wind.
1.2.4 Winds deflect or change direction because of **Coriolis** force.
1.2.5 The direction of the wind in the sketch above represents conditions in the **northern** hemisphere.
1.2.6 The greater the difference in air pressure between high-and low-pressure cells, the **stronger** the wind.
1.2.7 Geostrophic balance is commonly found in the **upper** atmosphere.
Feel free to proceed with the next questions or ask for any additional clarification!

1.2.1 The lines in the sketch showing places of equal pressure are known as
(contours/isobars).
1.2.2 The high pressure is represented by (5280/5100) hectopascals.
1.2.3 (Coriolis/Pressure gradient) force determines the speed of the wind.
1.2.4 Winds deflect or change direction because of (Pressure gradient/Coriolis)
force.
1.2.5 The direction of the wind in the sketch above represents conditions in the
(southern/northern) hemisphere.
1.2.6 The greater the difference in air pressure between high-and
low-pressure cells, the (stronger/weaker) the wind.
1.2.7 Geostrophic balance is commonly found in the (upper/lower) atmosphere.
