Hurricanes Quiz

What is the minimum wind speed for a storm to be classified as a hurricane?

• 74 miles per hour

• 39 miles per hour

• 95 miles per hour

• 150 miles per hour

Answer explanation

A storm is classified as a hurricane when its sustained wind speeds reach at least 74 miles per hour. This threshold distinguishes hurricanes from tropical storms, which have lower wind speeds.

What is the name given to hurricanes in the western Pacific Ocean?

• Tropical storms

• Typhoons

• Tornadoes

• Cyclones

Answer explanation

Hurricanes in the western Pacific Ocean are called typhoons. This term specifically refers to these powerful storms in that region, distinguishing them from tropical storms and cyclones found in other areas.

During which months do hurricanes typically occur in the Northern Hemisphere?

• January to March

• April to December

• June to September

• Mid-August to late October

Answer explanation

Hurricanes in the Northern Hemisphere typically occur from mid-August to late October, when ocean temperatures are warmest, providing the necessary conditions for their formation.

What happens to a hurricane when it moves over cooler water?

• It strengthens

• It gains speed

• It loses power

• It becomes a tropical storm

Answer explanation

When a hurricane moves over cooler water, it loses the warm water energy that fuels it, leading to a decrease in strength and intensity. Therefore, the correct answer is that it loses power.

What is the highest category a hurricane can reach?

• Category 4

• Category 6

• Category 3

• Category 5

Answer explanation

The highest category a hurricane can reach is Category 5, which indicates extremely dangerous conditions with sustained winds of 157 mph or higher. Categories 4 and 3 are lower on the scale.

What is the purpose of the National Hurricane Center?

• To monitor ocean temperatures

• To predict hurricane paths

• To provide evacuation routes

• To name hurricanes

Answer explanation

The National Hurricane Center's primary purpose is to predict hurricane paths, providing critical information for preparedness and response. While they also monitor ocean conditions and name storms, path prediction is their main focus.

What should you do before a hurricane hits?

• Stay outside

• Check your yard for broken branches

• Ignore local instructions

• Leave windows open

Answer explanation

Before a hurricane hits, it's important to check your yard for broken branches to prevent them from becoming dangerous projectiles. Staying outside, ignoring local instructions, or leaving windows open can increase risk.

What is a storm surge?

• A method of naming storms

• A type of hurricane

• A rise in ocean water pushed ashore

• A weather forecasting tool

Answer explanation

A storm surge is a rise in ocean water pushed ashore by strong winds and low pressure during storms, particularly hurricanes. This phenomenon can lead to significant coastal flooding, making it a critical aspect of storm impacts.

What is the main factor that fuels a hurricane?

• High pressure

• Cold air

• Low humidity

• Warm water

Answer explanation

Warm water is the main factor that fuels a hurricane, as it provides the heat and moisture necessary for the storm to develop and intensify. Without warm water, hurricanes cannot form or sustain themselves.

What should you do if you haven't evacuated during a hurricane?

• Go outside to check the weather

• Open all windows for ventilation

• Stay indoors in a safe place

• Use your cell phone constantly

Answer explanation

If you haven't evacuated during a hurricane, the safest option is to stay indoors in a secure location. This protects you from dangerous winds and flying debris, unlike going outside or opening windows.
