Understanding Hazardous Env. : Atmospheric Disturbances part 1

What are atmospheric disturbances?

• Atmospheric disturbances refer to the calm weather conditions in the atmosphere.

• Atmospheric disturbances are always caused by human activities.

• Atmospheric disturbances are variations in atmospheric conditions that affect weather patterns, including storms and cyclones.

• Atmospheric disturbances are only related to temperature changes.

Name three types of atmospheric disturbances.

• earthquakes

• hurricanes, tornadoes, thunderstorms

• volcanoes

• tsunamis

What is the primary hazard associated with high-speed winds?

• Lower temperatures and frost.

• Enhanced visibility and clear skies.

• Flying debris and structural damage.

• Increased humidity and rainfall.

How did Hurricane Dorian impact the Bahamas?

• Hurricane Dorian had minimal effects on the Bahamas.

• Hurricane Dorian brought only light rain to the Bahamas.

• Hurricane Dorian improved infrastructure in the Bahamas.

• Hurricane Dorian caused catastrophic damage, flooding, and loss of life in the Bahamas.

What causes storm surges during a cyclone?

• Tsunamis generated by distant storms

• Storm surges are caused by strong winds and low atmospheric pressure during a cyclone.

• Earthquakes beneath the ocean

• Heavy rainfall and flooding

Which cyclone resulted in over 138,000 fatalities in Myanmar?

• Cyclone Nargis

• Cyclone Sidr

• Cyclone Phailin

• Cyclone Gonu

What is the effect of prolonged rainfall on rivers?

• Prolonged rainfall decreases river levels.

• Prolonged rainfall has no impact on rivers.

• Prolonged rainfall causes rivers to dry up.

• Prolonged rainfall can cause rivers to overflow and flood surrounding areas.

What natural disaster can result from heavy rainfall and steep terrain?

• Earthquake

• Landslide or mudslide

• Hurricane

• Tsunami

How do atmospheric disturbances affect infrastructure?

• Atmospheric disturbances can damage infrastructure, disrupt services, and lead to economic losses.

• Atmospheric disturbances only impact wildlife, not infrastructure.

• Infrastructure is unaffected by atmospheric disturbances.

• Atmospheric disturbances improve infrastructure stability.

What role does low pressure play in storm surges?

• Low pressure leads to cooler ocean temperatures, preventing storm surges.

• Low pressure has no effect on sea levels during storms.

• Low pressure causes sea level rise and enhances wind-driven water movement, leading to storm surges.

• Low pressure decreases wave height, reducing storm surges.
