Global Atmospheric Movement 8.10B

Open Ended

If Earth’s surface was evenly heated by the sun, would there be winds? Why or why not?

Multiple Choice

What is atmospheric pressure?

• Atmospheric pressure is the force applied by the sun's rays on the Earth.
• Atmospheric pressure is the pressure exerted by the weight of the atmosphere in a given area.

• Atmospheric pressure is the weight of clouds in the sky, around 50 kPa.
• Atmospheric pressure is the pressure caused by ocean waves, roughly 80 kPa.

Multiple Choice

Which of the following statements best describes how wind forms?

• Wind forms when air moves from areas of high pressure to areas of low pressure.

• Wind forms when air moves from areas of low pressure to areas of high pressure.

• Wind forms when the sun heats the ground directly.

• Wind forms only at night when temperatures drop.

Multiple Select

Select all the factors that contribute to global wind patterns.

• Earth's rotation

• The Coriolis effect

• Differences in air pressure

• The shape of continents

Multiple Choice

Explain how differences in temperature at the poles and the equator affect global wind patterns.

• Differences in temperature at the poles and the equator create pressure variations that drive global wind patterns.
• Wind patterns are solely determined by ocean currents and not temperature variations.
• Pressure changes at the equator cause winds to blow towards the poles.
• Temperature differences lead to uniform wind patterns across the globe.

Multiple Choice

What causes air to move in the atmosphere according to the concept of differential heating?

• The rotation of the Earth

• The gravitational pull of the moon

• Convection due to the sun's energy heating Earth's surface

• The presence of mountains and valleys

Multiple Choice

How does uneven heating of Earth's surface contribute to the formation of global winds?

• Uneven heating of Earth's surface creates pressure differences that drive global winds.
• Uneven heating causes ocean currents that affect wind patterns.
• Uniform heating leads to stable air masses that prevent wind formation.
• Uneven heating creates temperature zones that block wind movement.
