Disaster 9

Read the passage to review the vocabulary you have learned. Answer the questions that follow.

 Nature challenges humans in many ways, through disease, weather, and famine.
For those living along the coast, one unusual phenomenon capable of catastrophic destruction is the tsunami (pronounced “tsoo-NAH-mee”).
A tsunami is a series of waves generated in a body of water by an impulsive disturbance.
Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of meteorites can generate tsunamis.
Starting at sea, a tsunami slowly approaches land, growing in height and losing energy through bottom friction and turbulence.
Still, just like any other water waves, tsunamis unleash tremendous energy as they plunge onto the shore.
They have great erosion potential, stripping beaches of sand, undermining trees, and flooding hundreds of meters inland.
They can easily crush cars, homes, vegetation, and anything they collide with.
To minimize the devastation of a tsunami, scientists are constantly trying to anticipate them more accurately and more quickly.
Because many factors come together to produce a life-threatening tsunami, foreseeing them is not easy.
Despite this, researchers in meteorology persevere in studying and predicting tsunami
behavior.

1. Which sentence best expresses the essential information of this passage?
a. Tsunamis could become a new source of usable energy in the next
hundred years.
b. Tsunamis do more damage to the land than flooding.
c. Tsunamis can have an especially catastrophic impact on coastal
communities.
d. Scientists can predict and track tsunamis with a fair degree of accuracy,
reducing their potential impact.

2. In the first sentence, why does the author mention weather?
a. because tsunamis are caused by bad weather
b. because tsunamis are more destructive than weather phenomena
c. as an example of a destructive natural force
d. as an introduction to the topic of coastal storms
