7

Which correctly lists three factors that are important to consider when forecasting weather?

A
clouds, isotherm, butterfly effect
B
isotherm, air pressure, temperature
C
air pressure, temperature, clouds
D
temperature, clouds, isotherm
8

Which event is associated with tornados?

A
sea levels rising due to high waves
B
coastal flooding due to storm surge
C
paths of damage up to 50 miles long
D

9

Which statement accurately describes the relationship between air pressure, air density, or altitude?

A
As altitude increases, pressure increases.
B
As altitude increases, air density increases.
C
Air pressure and density are lowest at sea level.
D
Denser air exerts more pressure than less dense air.
10

How is warm front formation different from occluded front formation?

A
A warm air mass rises above a cold air mass during a warm front, but two cold air masses surround a warm air mass during an occluded front.
B
Two cold air masses surround a warm air mass during a warm front, but a cold air mass moves against a warm air mass during an occluded front.
C
A cold air mass moves faster than a warm air mass during a warm front formation, but a cold air mass is pushed upward during an occluded front.
D
A warm air mass and a cold air mass form a boundary during a warm front, but water condenses between two air masses during an occluded front.
12

Which process contributes to the formation of tornados?

A
Water droplets freeze, giving off energy.
B
The storm begins to rotate around a central eye.
C
The Coriolis effect creates the spin of the storm.
D
Warm air rises, resulting in a decrease in air pressure.
