Report text 1

A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore.

These awe-inspiring waves are typically caused by large, undersea earthquakes at tectonic plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly, it displaces the water above it and launches the rolling waves that will become a tsunami.

Most tsunami, about 80 percent, happen within the Pacific Ocean's "Ring of Fire," a geologically active area where tectonic shifts make volcanoes and earthquakes common.

Tsunamis may also be caused by underwater landslides or volcanic eruptions. They may even be launched, as they frequently were in Earth's ancient past, by the impact of a large meteorite plunging into an ocean.

Tsunamis race across the sea at up to 500 miles (805 kilometers) an hour — about as fast as a jet airplane. At that pace they can cross the entire expanse of the Pacific Ocean in less than a day. And their long wavelengths mean they lose very little energy along the way.

A tsunami's trough, the low point beneath the wave's crest, often reaches shore first. When it does, it produces a vacuum effect that sucks coastal water seaward and exposes harbor and sea floors. This retreating of sea water is an important warning sign of a tsunami, because the wave's crest and its enormous volume of water typically hit shore five minutes or so later. Recognizing this phenomenon can save lives.

A tsunami is usually composed of a series waves, called a wave train, so its destructive force may be compounded as successive waves reach shore. People experiencing a tsunami should remember that the danger may not have passed with the first wave and should await official word that it is safe to return to vulnerable locations.

Some tsunamis do not appear on shore as massive breaking waves but instead resemble a quickly surging tide that inundates coastal areas.

6. From the text, we know that Tsunami can be very destructive because ...

• They come after earthquakes

  
  

• They are caused by volcanic eruptions

• They are tall, fast, forceful and repetitive

• They have a vacuum effect

• They occur suddenly

A kangaroo is an animal found only in Australia. It has a small relative called a wallaby, that lives in Tasmania and New Guinea. Kangaroos eat grass and plants. They have short front legs, long and strong back legs and a tail. These are used to sit up and jump. Kangaroos are well known for their 8-meter forward jumps and more than 3-meters high leap across fences. They can also run at the speed of over 45 kilometers per hour. The largest kangaroos are the Great Grey Kangaroos and Red Kangaroos. Adult kangaroos grow to a meter in length and 90 kilos in weight. Kangaroos are marsupials. This means that the female kangaroo has an external pouch on the front of her body. The baby kangaroo is very tiny when it was born. It right away crawls into its mother's pouch where it spends the first five months of its life.
