Population, Migration and Urbanization
Which of the following is the most common measure of population density?
a. Number of people per square kilometer.
b. Number of people per household.
c. Number of people per country.
d. Number of people per capital.
Number of people per square kilometer.
What happens to atmospheric pressure as a cold front approaches?
It falls.
As a cold front approaches, the pressure typically falls. After the front passes, the pressure begins to rise as the colder, denser air mass settles in.
What is a cold front?
The boundary where cold air replaces warm air.
What is the Saffir-Simpson Hurricane Wind Scale used to measure?
The intensity of a hurricane based on its wind speed.
Name TWO major weather systems that commonly occur in the Caribbean.
Tropical waves
Cold fronts
Anticyclones.
A population pyramid with a wide base and a narrow top typically indicates:
a. An aging population.
b. A high birth rate and a young population.
c. Zero population growth.
d. A declining population.
A high birth rate and a young population.
What is a tropical wave?
A trough of low pressure that moves from east to west across the tropics, often bringing unsettled weather.
What type of precipitation is most commonly associated with the passage of a cold front in the Caribbean?
Showers and thunderstorms
The lifting of warm, moist air by the advancing cold air mass often leads to the formation of cumulonimbus clouds, resulting in showers and thunderstorms
What is storm surge?
Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tide. It is caused by the strong winds of a hurricane pushing water towards the coast.
Where do the hurricanes that affect the Caribbean region usually form?
1. Atlantic, off the west coast of Africa.
2. Caribbean Sea
3. Gulf of Mexico
Which factor is LEAST likely to influence the birth rate of a country?
a. Level of education.
b. Availability of education and health planning services.
c. Government policy on immigration.
d. Cultural and religious beliefs regarding family size.
Government policy on immigration.
What type of weather is often associated with the passage of a tropical wave?
Increased cloudiness, showers, and thunderstorms.
As a tropical wave passes, the convergence of air within the trough can lead to increased cloudiness, showers, and thunderstorms.
Which of the following is NOT a typical characteristic of a hurricane's eye?
a. Calm winds Clear skies or light clouds
b. Very strong winds and heavy rainfall
c. Low atmospheric pressure
Very strong winds and heavy rainfall
The eye of a hurricane is characterized by calm winds, clear skies, and low pressure. Very strong winds and heavy rainfall occur in the eyewall surrounding
What is the term for a tropical cyclone when its maximum sustained winds are between 39 and 73 mph?
Tropical storm
Define the term hazard.
An event that poses a threat to the environment, life and/or property.
The 'demographic transition model' describes the historical shift in population patterns from:
a. High birth and deaths rates to low birth and death rates.
b. Low births and death rates to high death and birth rates.
c. High birth rates and low death rates to low birth rates and high death rates.
d. Low birth rates and high death rates to high death rates and low death rates.
High birth and deaths rates to low birth and death rates.
Tropical waves are considered precursors to which larger weather phenomenon?
Tropical cyclone/hurricane
Which direction does a cold front typically move across the Caribbean?
Cold fronts generally move from northwest to southeast, meaning they typically approach the Caribbean from the north or northeast.
Which of the following is the most common type of weather system that affects the Caribbean from June to November?
Hurricane-Tropical Cyclone
Define the term disaster.
An event that causes destruction and damage to the environment, life and/or property.
What is the primary cause of a declining death rate in Stage 2 of the demographic transition model?
a. Increased agricultural productivity and food supply.
b. Widespread adoption of family planning.
c. A decrease in the number of people of reproductive age.
d. A rise in infectious diseases
Increased agricultural productivity and food supply.
What is the typical speed at which a tropical wave moves?
Tropical waves typically move at a moderate pace, generally between 10 to 20 mph, though their speed can vary.
When a cold front passes through the Caribbean, what is a typical change in temperature experienced?
Temperature decreases.
As a cold front passes, the colder, denser air displaces the warmer air, leading to a noticeable drop in temperature.
Explain how hurricanes can directly affect infrastructure in urban areas.
1. High wind-roofing
2. Storm surge-coastal flooding
3. Intense rainfall-flooding of low-lying areas
4. Mass wasting-landslides due to heavy rainfall
Define the term mitigation.
Any action taken in an attempt to lessen the impact of a disaster.
