Air Mass Movement Practice Test

A student draws a model to show air movement. Air moves due to pressure differences, from high pressure toward low pressure.

Student model:

• Left side is labeled H
• Right side is labeled L
• The arrow is drawn from the right side toward the left side (L → H)

Which evaluation is best supported by the model and the rule about pressure?

A weather map model includes pressure and temperature clues:

• Mountain Valley: H (High Pressure), cold air shown with a snowflake icon
• Coastal Plain: L (Low Pressure), warm air shown with a sun icon Arrows are used to show the expected air movement.

Which claim is incorrect based on the model and the idea that air moves due to pressure differences?
