Natural Disasters

What is the primary cause of earthquakes?

• Alien invasion

• Movement of tectonic plates

• Volcanic eruptions

• Global warming

How are tornadoes different from hurricanes?

• Tornadoes are smaller in size and shorter in duration compared to hurricanes.

• Tornadoes only occur in coastal areas while hurricanes only occur in inland regions

• Tornadoes are the same size as hurricanes but last longer

• Tornadoes are caused by heavy rain while hurricanes are caused by strong winds

What are the categories used to measure the strength of hurricanes?

• Fujita scale

• Saffir-Simpson scale

• Richter scale

• Beaufort scale

What is the most common cause of floods?

• Volcanic eruptions

• Earthquakes

• Tornadoes

• Heavy rainfall and rapid snowmelt

What are the warning signs of a volcanic eruption?

• No changes in seismic activity, no changes in the shape of the volcano, and no release of gases and steam

• Decreased seismic activity, changes in the shape of the volcano, and the release of gases and steam

• Increased seismic activity, changes in the shape of the volcano, and the release of gases and steam

• Increased rainfall, changes in the color of the volcano, and the release of lava

How do wildfires spread?

• By people intentionally setting them off

• By the ignition of dry vegetation and fueled by wind and weather conditions.

• By the release of toxic gases from the ground

• By the movement of tectonic plates

What are the safety measures to take during an earthquake?

• Running outside as fast as possible

• Taking a hot shower

• Taking cover under a sturdy piece of furniture, staying away from windows, and staying indoors until the shaking stops.

• Standing near a tall bookshelf

What are the key differences between a pyroclastic flow and a lava flow during a volcanic eruption?

• The key differences are the shape and size of the flows.

• The key differences are the speed and composition of the flows.

• The key differences are the smell and sound of the flows.

• The key differences are the color and temperature of the flows.

What are the factors that contribute to the formation of a tornado?

• Tornadoes are a result of high altitude winds

• Atmospheric conditions and the interaction between warm, moist air and cold, dry air.

• Tornadoes are caused by volcanic eruptions

• Tornadoes are formed due to excessive rainfall

How can human activities contribute to the occurrence of natural disasters?

• Human activities can contribute to natural disasters through wildlife conservation

• Human activities can contribute to natural disasters through space exploration

• Human activities can contribute to natural disasters through renewable energy sources

• Human activities can contribute to natural disasters through deforestation, urbanization, and industrialization.
