3.1 Global atmospheric circulation

What causes the UK to have cloudy and wet weather?

• Being an island

• Collision of cold polar and warm subtropical air masses

• Lack of volcanic action

• I don't know yet

Why are deserts typically hot and dry?

• Constant high temperatures from the sun's rays

• High-pressure zones that stop cloud formation

• Lack of vegetation causing less humidity

• I don't know yet

What is responsible for the heavy rainfall in equatorial regions?

• Persistent low-pressure

• Persistent high pressure

• Warmest temperatures

• I don't know yet

Which factor does not affect global atmospheric circulation?

• Earth's magnetic field

• Earth's rotation

• The tilt of the Earth's axis

• I don't know yet

What is the Coriolis effect?

• The impact of solar flares on the atmosphere

• The deflection of winds due to Earth's rotation

• The change in weather with the phases of the moon

• I don't know yet

Why does global atmospheric circulation change with seasons?

• The Earth gets closer and further from the sun

• The Earth's tilt and rotation change the sun's position relative to the Earth

• The ocean currents reverse direction

• I don't know yet

Which latitude is most associated with desert climates?

• 0° (Equator)

• 30° North and South

• 60° North and South

• I don't know yet

What is not a characteristic of high-pressure zones?

• Cool, sinking air

• Clear skies and dry weather

• Frequent and heavy rainfall

• I don't know yet

How do the global atmospheric circulation cells affect Earth's climate?

• They have no significant impact

• They create uniform climate zones across the Earth

• They distribute heat and moisture, affecting climate zones

• I don't know yet

How does the Earth’s tilt affect seasonal weather changes?

• It changes the direction of ocean currents

• It alters the concentration of the ozone layer

• It causes relative changes in the position of the overhead sun

• I don't know yet
