Match the two halves of the sentences to make up a phrase. 4)
World disasters
There are many different disasters in the world. Such natural disasters as tsunamis, hurricanes, floods, droughts, earthquakes, volcanic eruptions, and tornadoes often happen in any part of the we world. Natural disasters often destroy people's houses and harm people.

One of the most powerful disasters is a tsunami. It is a large wave, which moves to the seashore. Earthquakes can cause a tsunami. Earthquakes are another disaster that happen because of the movements in the Earth's crust. When an earthquake happens, everything shakes and falls in the buildings. If an earthquake is strong, it can ruin buildings and roads.
Tsunami and heavy rains also can cause floods. For example, in India, there are monsoon rains that make the level of the river higher, and many people have to leave their places of living. In other parts of the planet, there are different problems. Summer heat can cause fire, and this can harm both people and animals. In 2019, an Australian fire destroyed many animals, and people couldn't put out
the fire for a long time.
Fortunately, people have created different systems that can warn about coming natural disasters. Such systems help save many people and animals from injuries.
