Natural Hazards

What is the primary cause of earthquakes?

• Volcanic eruptions

• Global warming

• Alien interference

• Movement of tectonic plates along fault lines

Which scale is commonly used to measure the magnitude of earthquakes?

• Fahrenheit scale

• Kelvin scale

• Celsius scale

• Richter scale

How are tornadoes formed?

• Tornadoes are a result of excessive cloud dancing

• Tornadoes are created by underground explosions

• Tornadoes are formed when warm, moist air collides with cold, dry air, creating instability in the atmosphere.

• Tornadoes are formed by aliens manipulating the weather

What is the main difference between a flash flood and a river flood?

• Flash floods occur suddenly with little warning, while river floods develop over time.

• Flash floods are more common in rural areas, while river floods are more common in urban areas.

• River floods are caused by excessive rainfall, while flash floods are caused by dam breaks.

• River floods are more dangerous than flash floods due to their slow-moving nature.

What is the Ring of Fire known for in relation to volcanic eruptions?

• Volcanic eruptions only in winter

• No volcanic activity

• Frequent and large volcanic eruptions

• Rare and small volcanic eruptions

What are the categories used to classify hurricanes based on their wind speeds?

• Category A (50-70 mph), Category B (71-90 mph), Category C (91-110 mph), Category D (111-130 mph), Category E (131 mph or higher)

• Level 1 (75-95 mph), Level 2 (96-110 mph), Level 3 (111-125 mph), Level 4 (126-150 mph), Level 5 (151 mph or higher)

• Category 1 (74-95 mph), Category 2 (96-110 mph), Category 3 (111-129 mph), Category 4 (130-156 mph), Category 5 (157 mph or higher)

• Grade 1 (80-100 mph), Grade 2 (101-120 mph), Grade 3 (121-140 mph), Grade 4 (141-160 mph), Grade 5 (161 mph or higher)

What factors contribute to the spread of wildfires?

• Urban development

• Low temperatures

• Dry weather conditions, high winds, flammable vegetation, human activities

• Heavy rainfall

• Excessive humidity

How can deforestation impact the likelihood of landslides during heavy rainfall?

• Deforestation can reduce the likelihood of landslides during heavy rainfall

• Deforestation can lead to soil erosion and destabilization, making slopes more prone to landslides when heavy rainfall occurs.

• Deforestation has no impact on the likelihood of landslides during heavy rainfall

• Deforestation can increase vegetation growth and prevent landslides during heavy rainfall

What is the role of emergency preparedness in mitigating the impact of natural hazards?

• Emergency preparedness increases casualties during natural disasters

• Emergency preparedness delays responses to natural disasters

• Emergency preparedness plays a crucial role in mitigating the impact of natural hazards by enabling timely and organized responses to emergencies, reducing casualties, and minimizing damage.

• Emergency preparedness has no impact on mitigating natural hazards

Why is it important to have evacuation plans in place for areas prone to natural disasters?

• To create chaos and confusion during emergencies

• To save lives by providing organized and efficient routes to safety, reducing panic and confusion during emergencies.

• To encourage people to stay in dangerous areas

• To increase the risk of casualties by not having a plan
