Section 2-3 "Lesson Question II - How do Wind's Form?"

Air blows at the base of circulation cells from an area of  _________ pressure to an area of  _____________ pressure.

• Low, High
• High, Low
• Low, Low
• High, High

The global winds blow in the direction of

• The top of the atmospheric circulation cells.
• The rotation of the Earth.
• The base of the atmospheric circulation cells.
• Towards the prevailing side of the wind

Sinking air

• Has lower Pressure
• Causes evaporation
• Has Lower temperature
• all of these

What role does air pressure play in weather conditions?

• Its force determines the strength of the wind
• It creates downdrafts that blow from the shore
• It is the primary cause of the trade winds
• It determines how high or low the tide is

What gives wind its mass?

• barometric pressure
• air molecules
• air pressure
• the convection cell

Which three elements affect air pressure?

• Wind, earth's distance from the moon, & oceans
• amount of plants, winds, & level of water in the oceans
• height above sea level, temperature, & amount of water vapor
• temperature, wind, and how much animal and plant life is around

What is a convection cell?

• an extremely dense and heavy mass of air
• a place on the beach where scientists watch the weather
• an instrument scientists use to measure wind speeds
• a pattern of rising warm air and sinking cool air

Why does air rise over land at the beach?

• Cold air gets warmer over land, which makes it lighter, so it rises
• Warm air over the sea moves inland, gets cooler, and then rises
• Trade winds around the equator blow the air higher at the beach
• Land is cooler than the water at the beach, so the air repels away from it

Which of the following best describes the coriolis effect?

• As cool air warms up, it rises, and as warm air cools down, it sinks, creating a breeze
• As the sun rises and sets, the path of the wind all over the Earth changes direction
• As the Earth spins on an axis, the Earth pulls the wind and causes it to blow in a curved path
• As the air pressure on the Earth’s poles changes, the wind at the equator becomes stronger

Which type of global wind current blows across most of the United States?

• Polar Easterlies
• Prevailing Westerlies
• Trade Winds
• Doldrums
