Air mass that formed over the north pole is cold and dry, while an air mass that formed over a warm ocean is warm and moist.

• Air mass from the north pole is cold and dry, while the air mass from a warm ocean is warm and moist.

• Both air masses have similar characteristics.

• Air mass from the north pole is warm and moist, while the air mass from a warm ocean is cold and dry.

• Air mass from the north pole is highly humid, whereas the air mass from a warm ocean is dry.

Meteorologists indicate different types of weather fronts on a weather map by:

• Using symbols such as triangles for cold fronts and semicircles for warm fronts

• Using colored lines only with no symbols

• Using temperature gradients

• Using wind direction markers

9. Weather formation with an occluded front - determine the resulting weather condition.

• Cloudy with rain

• Clear and sunny

• Foggy conditions

• Windy and dry
