1,386 Questions
Natural hazards and disasters involve the study of extreme natural events like earthquakes, floods, and cyclones, alongside their management and mitigation strategies. This geography and environmental studies topic is heavily tested in civil services and state public service examinations. Use these questions to prepare for inquiries on disaster response, community recovery, and tremor causes.

Natural Hazards and Disasters Questions
-
Hurricane
-
Lightning
-
Thunder
-
Rain
A
Correct answer
Explanation
A hurricane is a tropical cyclone characterized by strong winds and heavy rain - it's specifically defined by its powerful wind component. Lightning and thunder are electrical phenomena, while rain is just precipitation.
-
Katrina
-
Wilma
-
Dean
-
Gustav
-
Cyclone
-
Tornado
-
Snowfall
-
Tsunami
B
Correct answer
Explanation
The Enhanced Fujita Scale (EF-Scale) is specifically used to measure tornado intensity based on wind damage. It replaced the original Fujita Scale in 2007. It's not used for cyclones, snowfall, or tsunamis - each has its own measurement scale.
-
Fire
-
Tsunami
-
Ice berg
-
A Volcano
D
Correct answer
Explanation
In a volcano, the 'thunder' (rumbling) precedes the 'lightning' (volcanic lightning), and the 'rain' (lava) is hot and dries/burns the land.
-
Limnophobia
-
Lilapsophobia
-
Linonophobia
-
Liticaphobia
B
Correct answer
Explanation
Lilapsophobia is the fear of tornadoes and hurricanes. The prefix 'lilaps' comes from Greek meaning violent storm or hurricane. Limnophobia is fear of lakes, Linonophobia is fear of string, and Liticaphobia is fear of lawsuits.
-
Hurricane
-
Typhoon
-
Cyclone
-
Tornado
C
Correct answer
Explanation
The Indian Ocean region, including the Bay of Bengal, uses the term 'Cyclone' for tropical storm systems. 'Hurricane' is used in the Atlantic and Northeast Pacific, while 'Typhoon' is used in the Northwest Pacific. A tornado is a completely different weather phenomenon occurring over land.
-
Cyclones
-
Tornados
-
Hurricanes
-
Tsunamis
A
Correct answer
Explanation
The Indian Ocean is characterized by a greater frequency of cyclones compared to other ocean basins. Cyclones are tropical storm systems that form in warm ocean waters. The term 'cyclone' is used in the Indian Ocean and South Pacific. 'Hurricane' is used in the Atlantic and Northeast Pacific. 'Tornado' refers to land-based storms. 'Tsunami' refers to ocean waves from seismic events, not weather systems.
-
earthquakes
-
floods
-
forest fires
-
landslides
C
Correct answer
Explanation
Forest fires are a natural cause of global warming. They release large amounts of CO2 and other greenhouse gases stored in trees and vegetation, and reduce future carbon absorption capacity. Unlike earthquakes or landslides, fires directly affect atmospheric composition.
-
Firecrackers bursting by people
-
Pollution in the skys
-
Celebrating Bonfire night early
-
Due to wreath of God
C
Correct answer
Explanation
In the Harry Potter universe, when wizards celebrate Bonfire Night early with magical fireworks, Muggle weathermen and news outlets attempt to explain the phenomenon as natural meteor showers or shooting stars. The other options (firecrackers, pollution, divine wrath) are plausible Muggle explanations but not the specific one given in the text.
-
waterspouts
-
underwater earthquakes
-
full moons
-
none of the above
C
Correct answer
Explanation
The Bermuda Triangle has several scientifically plausible environmental explanations including waterspouts (tornadoes over water) and underwater earthquakes that can cause rogue waves. Full moons are not typically cited in scientific discussions as a direct cause of disappearances, though they appear in supernatural or speculative theories.
-
Samoa Islands
-
Andaman & Nicobar Islands
-
Honshu
-
Guinea
-
the flood stage
-
the flood recurrence interval
-
the flood frequency
-
the flood incidence
B
Correct answer
Explanation
The flood recurrence interval is the average time between floods of a given magnitude, calculated from historical records. It's a statistical measure used in flood hazard assessment and planning.
-
an interval of time during which stream discharge exceeds the capacity of the stream channel
-
an interval of time during which stream velocity increases its discharge
-
an interval of time during which a stream occupies its flood plain
-
none of these is an adequate definition of a flood
A
Correct answer
Explanation
A flood is defined as when stream discharge exceeds the channel's capacity, causing water to spill onto floodplains. This is the standard hydrological definition used by geologists and hydrologists.
-
The Eruption of Krakatoa.
-
The Bubonic plague.
-
The Great Tree Falling Incident of 1872.
-
The San Fransican earthquake.
B
Correct answer
Explanation
The bubonic plague (Black Death) is widely considered the deadliest natural disaster in recorded history, killing an estimated 75-200 million people across Eurasia and North Africa in the 14th century.
-
Texas.
-
Washington state.
-
Arkansas.
-
Florida.
A
Correct answer
Explanation
The 1900 Galveston hurricane in Texas remains the deadliest natural disaster in U.S. history, killing approximately 6,000-12,000 people. This Category 4 hurricane struck Galveston Island on September 8, 1900.
