Natural Disasters and Their Causes

Geo-hazards are natural events that threaten human life and the environment. Examples include earthquakes, volcanic eruptions, landslides, tsunamis, floods, hurricanes, wildfires, sinkholes, avalanches, and droughts. Each has unique causes and impacts, such as ground shaking from earthquakes or water overflow in floods. Understanding these hazards helps mitigate their effects on communities and ecosystems.

What are geo-hazards primarily known for?

• Creating new landforms

• Posing threats to human life and the environment

• Improving weather conditions

• Providing resources for human use

What causes the ground to shake during an earthquake?

• Volcanic eruptions

• Strong winds

• Heavy rainfall

• Movement of tectonic plates

Which of the following is a result of volcanic eruptions?

• Tsunamis

• Lava flows

• Sinkholes

• Droughts

What often triggers landslides?

• Snowfall

• Heavy rainfall

• High temperatures

• Strong winds

How are tsunamis typically generated?

• By volcanic eruptions on land

• By strong winds
