Review 1

Question	Answer
Give examples of Geophysical hazards.	1. Volcanic eruption 2. Earthquake 3. Tsunamis
Give examples of Hydro-meteorological hazards.	1. Drought 2. Flood 3. Storm
Explain the chronic hazards and give examples.	A hazard that is long term and persistent e.g. El-Nino or Global Warming
Give factors that may increase the vulnerability.	1. High population density 2. More Aged people 3. Lack of education and training 4. Poverty 5. Rapid urbanisation
What is Albedo??	how much solar radiation a surface reflects
As global warming occurs, higher temperature causes more ice to melt, so there is less albedo. This leads the temperature increasing and makes the remaining ice melt quicker. SO, this process is a POSITIVE or NEGATIVE feedback????	POSITIVE
Explain, with the help of examples, the difference between hazards and disasters.	Refer to pages 2 and 3.
Why a rapid urbanisation in in developing countries may increase the vulnerability?	1. Pressure on land, people live in high-risk areas such as low-lying places. 2. Poor facilities such as drainage system. 3. As more people, difficult to evacuate before the hazard comes.
Which of the hydro-meteorological hazards do you think threatens the greatest disaster: drought, floods, or tropical cyclones and storms??	Accept any reasonable answer.
Define the term El Nino	refers to the event that causes warmer than usual SSTs to accumulate in the Eastern Equatorial Pacific
Define the term La Nina	refers to colder than average SSTs in East Equatorial Pacific
