Natural disasters are very bad events that happen in nature. They can cause a lot of harm to people, animals, and the environment. In the past (1) of years, natural disasters have happened very often. Some common ones include floods, droughts, earthquakes, tsunamis, and typhoons.
Floods usually happen when there is too much rain. Rivers overflow, and water covers the land. Fields and houses are washed (2), and many people lose their homes. Drinking water gets (3), too. In 2023, many places around the world had big floods, making thousands of people (4).
Droughts are the opposite of floods. When there is little or no rain for a long time, droughts happen. The land becomes dry, and plants can't grow. This can lead to food shortages, especially in places that depend a lot (5) farming.
Earthquakes are sudden and very scary. The ground shakes, and buildings can fall down. In 2024, a strong earthquake hit some countries, killing many people and (6) many buildings. People were trapped under the ruins, and it was very hard to save them.
Tsunamis are huge waves in (7) ocean. They are often caused by underwater earthquakes. Tsunamis can travel very fast and hit the coast with great force. They can destroy everything along the shore, like houses, roads, and boats.
Typhoons are big, (8) storms. They bring strong winds and heavy rain. Typhoon winds can blow down trees and power lines. The heavy rain can cause floods and landslides.
Most natural disasters are caused by nature, but sometimes human activities make them even (9). For example, cutting down too many trees can make floods and landslides more likely to happen.
When natural disasters happen, governments and people work together to help. Rescuers save people (10) in the disaster areas, and doctors take care of the injured. We can also help by donating money or things to the people affected by the disasters. As students, we should learn about natural disasters so that we can protect ourselves and help others when they happen.
