A. River with waterfalls
B. River with sedimentary islands
C. River formed from glaciers
D. River that freezes in winter
⬛ Answer: B – These rivers have channels that split and rejoin, often around sediment
bars.
2. Which of the following atmospheric layers is closest to the Earth’s surface?
A. Stratosphere
B. Thermosphere
C. Mesosphere

⬛ Answer: C – Warm waters above 80°F fuel cyclones.
,4. Which direction do hurricanes rotate in the Northern Hemisphere?
A. Clockwise
B. Counterclockwise
C. Eastward
D. Randomly
⬛ Answer: B – Due to the Coriolis effect, storms rotate counterclockwise in the
Northern Hemisphere.
5. What does a hook echo on radar indicate?
A. Fog
B. Heavy rain
C. Tornado potential
D. Hailstorm
⬛ Answer: C – Hook echoes are classic radar signatures of tornadic rotation.
6. What is the Enhanced Fujita Scale used for?
A. Measuring rainfall
B. Tornado damage assessment

A. Cool, descending air
B. Updrafts in supercells
C. Mountain winds
D. Frontal boundaries
⬛ Answer: B – Wall clouds are formed by strong updrafts in rotating supercells.
8. Which radar tool can detect debris in a tornado?
A. Reflectivity only
B. Dual-polarization radar
C. Doppler base velocity
, D. Satellite infrared
⬛Answer: B – Dual-polarization radar distinguishes debris from rain.
9. What part of a hurricane is the most dangerous?
A. Left-rear quadrant
B. Eye
C. Right-front quadrant
D. Outer bands
⬛ Answer: C – The right-front quadrant has the strongest winds and storm surge.
10. What does a hydrograph show?
A. Wind speed over time
B. River discharge over time
C. Humidity levels
D. Rainfall rate

11. Which of the following defines wind shear?
A. Sudden increase in pressure
B. Change in wind direction or speed with height
C. Rapid cooling of air mass
D. Increase in humidity
⬛ Answer: B – Wind shear involves vertical or horizontal changes in wind.
12. A debris ball on radar most likely indicates:
A. Hail shaft
B. Tornado in progress
C. Flooding
