Air Masses & Wind: StudyJams Quiz

What role does air pressure play in weather conditions?

• Its force determines the strength of wind.

• It creates downdrafts that blow from the shore.

• It is the primary cause of 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

What three elements affect air pressure?

• wind, Earth’s distance from the Moon, and clouds

• amount of plants, wind, and level of water in the ocean

• height above sea level, temperature, and amount of water vapor

• temperature, wind, and how much plant or animal life is around

What is a convection cell?

• extremely dense and heavy masses of air

• a place on the beach where scientists watch weather

• an instrument scientists use to measure wind speeds

• a pattern of rising warm air and sinking cold air

Why does air rise over the 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 water at the beach, so the air repels away from it.

Which best describe 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 Earth changes directions.

• As it spins on its 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.
