UNIT 1 LIGHTNING PART 1 TEXT

What is the main topic of the passage?

• Cause of Death

• Lightning

• Forest Fire

• Sky

What is the approximate number of lightning bolts that strike the earth in one day?

• 1 million

• 5 million

• 10 million

• 50 million

Why should people be afraid of lightning, according to the text?

• Lightning causes significant damage to electrical systems.

• Lightning is responsible for many deaths and injuries each year.

• Lightning is rare and unpredictable.

• Lightning disrupts weather patterns and climate.

What is the relationship between lightning and forest fires as mentioned in the text?

• Lightning is the main cause of forest fires, starting over 9,000 fires annually.

• Lightning indirectly causes fires by disrupting power lines.

• Lightning prevents forest fires by producing rain.

• Lightning starts only a few forest fires each year.

What do scientists know about the electricity inside a cloud?

• Scientists know exactly how the electricity is formed.

• The electricity inside a cloud can reach up to 50 million volts.

• The electricity inside a cloud can be as much as 100 million volts.

• The electricity in a cloud is weak and harmless.

What comparison is made to emphasize the temperature of a lightning bolt?

• It is hotter than boiling water.

• It is hotter than the surface of the sun.

• It is as hot as a volcano.

• It is colder than space.

Based on the information given, why might lightning be more dangerous than other sources of electricity?

• Because its voltage is lower than that of household electricity.

• Because it can be unpredictable and comes from the sky.

• Because it takes time to form and can be avoided.

• Because it has a lower temperature than other sources of electricity.

What can we infer about the dangers of lightning based on its temperature and voltage?

• Lightning is dangerous because it is very hot and carries a high voltage.

• • Lightning is dangerous primarily because it is bright.

• Lightning is safe as long as it doesn't strike a person directly.

• Lightning is only dangerous at night due to reduced visibility.

What is thunder, according to the text?

• The sound of the lightning bolt hitting the ground

• • The sound of air being pushed by the wind

• The sound of the rain falling due to lightning.

• The sound of hot air exploding

Why do we see lightning before we hear thunder?

• Thunder happens after lightning.

• Thunder and lightning happen at different times.

• Thunder is quieter and harder to hear.

• Light travels faster than sound.
