Natural Hazards and Disasters

Front

What is the primary cause of earthquakes?

Back

Movement of tectonic plates

Front

How are tornadoes formed?

Back

Tornadoes are formed from powerful thunderstorms.

Front

What are the main factors that contribute to flooding?

Back

Heavy rainfall, rapid snowmelt, inadequate drainage systems, and deforestation

Front

Explain the process of a volcanic eruption.

Back

Magma from within the Earth's mantle rises to the surface, causing pressure to build up and eventually leading to an explosive release of gases, ash, and lava.

Front

What are the key characteristics of hurricanes?

Back

Strong winds, heavy rainfall, storm surges, and potential for widespread damage

Front

How do wildfires start and spread?

Back

Wildfires start from a variety of sources, including human activity, lightning, and lava. They spread through the ignition of dry vegetation and can be fueled by wind and weather conditions.

Front

What are the different categories of tornadoes based on their intensity? Options: Enhanced Fujita (EF) scale, Beaufort scale, Saffir-Simpson scale, Richter scale

Back

Enhanced Fujita (EF) scale

Front

Describe the impact of flooding on the environment and human settlements.

Back

Flooding can cause damage to infrastructure, loss of life, displacement of people, contamination of water sources, destruction of crops, and loss of biodiversity.

Front

What are the warning signs of an impending volcanic eruption?

Back

Observing ground deformation, increased seismic activity, changes in gas emissions, and changes in water and ground temperature

Front

Discuss the measures that can be taken to prepare for and mitigate the impact of natural disasters.

Back

Creating emergency plans, building resilient infrastructure, conducting regular drills, and educating the community about disaster preparedness
