Air Masses, Fronts and Atmospheric Pressure

Which atmospheric layer is Most Likely represented by layer D and why?

• The thermosphere because air pressure decreases as altitude increases.

• The troposphere because air pressure increases as altitude decreases.

• The troposphere because air pressure decreases as altitude decreases.

• The thermosphere because air pressure increases as altitude increases.

Daniella drew this model of a hot summer day at the beach. What is demonstrated by Daniella's model?

• Strong rotating winds as caused by the rhythmic pattern of ocean tides.

• The Coriolis effect as it affects the directions of global winds.

• local winds as influenced by unequal heating and topographical features.

• global winds as influenced by variations in temperature and the rotation of the Earth.

To model the interaction between unequal heating and the rotation of Earth, a student placed a heat lamp beside a globe, then spun the globe from west to east. Likely, the student used this model to show which of the following is MOST affected by unequal heating and westerly rotation of the Earth?

• The average daily temperature at points along the Equator and at the poles.

• the circumference of Earth at the Equator and at the Poles.

• The direction of the winds moving over Earth's surface.

• the tilt of Earth on its axis.

• The air pressure remains stable

• There is a rapid shift in wind direction

• There is a change in moisture content

A group of students conducted an investigation in which they simulated a weather event. They filled a square, plastic container almost full of lukewarm water, placed a blue ice cube at one end of the container, and added three drops of red food coloring at the other end of the container. As the ice started to melt, the blue water was observed in the container. Which BEST predicts and explains the outcome?

• The cold blue water will sink while the warm red water rises in the container, much like a thunderstorm can form due to an approaching cold front causing warm air to rise.

• The warm red water will sink while the cold blue water rises in the container, much like a thunderstorm can form due to an approaching cold front causing warm air to sink.

• The cold blue water will force the warm red water to sink, and as the warm red water rises through the cold blue water, it will begin to rotate, much like the formation of a tornado in which the rising of the warm air creates horizontal rotation.

• The warm red water will force the cold blue water to sink, and as the cold blue water sinks through the warm red water, it will begin to rotate, much like the formation of a tornado in which the sinking of the cold air creates horizontal rotation.
