ответ:task1.Natural disasters like earthquakes, tornado, tsunami and floods happen more frequently nowadays. There are many reasons why they occur, but the main one is related to human activity on Earth which often has a negative impact on our environment.
All kinds of disasters are usually very damaging. Many dwellings, roads and even whole streets and cities are ruined. The number of victims usually terrifies as hundreds or even thousands of people get injured or die in disasters. However, each disaster has a different nature.
For example, an earthquake is the result of the tectonic plates’ movement which leads to the shaking of a certain area on land. Earthquakes destroy buildings and people usually become victims because they get stuck or killed under the rubble.
Tornado is also a natural disaster which looks like an enormous column of the wind which lifts cars, bicycles, furniture and many other things. It is also called a twister and it can be very dangerous if touches the surface of the ground or water.
Flood in its turn happens when rivers burst their banks. Most extended floods damage cities and wash away whole populated places. Tsunami is another natural disaster which arises as a series of huge waves caused by underwater earthquakes.
Thus, there are many natural disasters which are dangerous for all of us. We should be careful and treat our planet better in order not to die with it.
