Hurricane Formation and Impact

The video explains why the US coastline is vulnerable to hurricanes, tracing their origins to atmospheric disturbances over Africa known as easterly waves. These waves develop into thunderstorms, which organize and strengthen over the warm Atlantic waters, eventually forming hurricanes. The video details the process of hurricane formation, including the development of an eye and eye wall, and highlights the significant impact these storms have when they make landfall in the US.

What is the primary reason the US coastline is susceptible to hurricanes?

• Proximity to the equator

• Origin of hurricanes in the Atlantic

• Lack of protective barriers

• High population density

What is an easterly wave?

• A type of wind in the Arctic

• A type of ocean current

• A small atmospheric disturbance

• A weather pattern in the Pacific

What can trigger the development of an easterly wave?

• A small event like a dust devil

• A change in ocean temperature

• A volcanic eruption

• A large storm system

What happens to easterly waves as they move west across Africa?

• They become weaker

• They turn into tornadoes

• They develop into clusters of thunderstorms

• They dissipate over the desert

What role does the warm tropical water of the Atlantic play in hurricane formation?

• It blocks the storms

• It redirects the storms northward

• It provides moisture and heat energy

• It cools down the storms

How do thunderstorms become more organized in the Atlantic?

• By moving northward

• By rotating around each other

• By dissipating

• By merging with other storms

What is the 'heat engine' of a hurricane?

• The warm ocean water

• The eye of the storm

• The cold air from the poles

• The landmass it encounters

At what wind speed does a storm typically develop an eye?

• 110 mph

• 50 mph

• 70 mph

• 90 mph

What is the eye wall of a hurricane?

• The outermost part of the storm

• A region of intense heat and strong winds

• The calm center of the storm

• A protective barrier around the storm

What is the impact of hurricanes when they make landfall in the US?

• They bring beneficial rain

• They cause enormous damage

• They improve air quality

• They reduce temperatures
