These events can destroy homes, damage crops (庄稼), and even cause death, leaving terrible effects on humans and the environment. While some disasters are hard to predict (预测), learning about them helps people stay safe and prepare better for emergencies. Tsunamis Tsunamis are huge ocean waves usually triggered (触发) by underwater earthquakes or volcanic eruptions(火山爆发). They can travel across the ocean at high speed and hit coastal areas, sweeping away everything in their path. In 2004, a huge tsunami hit many countries in Southeast Asia, causing great loss of life and property(财产). Floods Floods happen when heavy rain, melting snow, or heavy storms make water rise and cover land that is usually dry. They often occur in low-lying areas or near rivers. Floods can destroy buildings, pollute drinking water, and cut off roads, making it hard for people to get help quickly. Wildfires Wildfires are terrible fires that spread fast through forests or grasslands. They can be started by lightning, human carelessness, or extreme (极端的) heat and drought. Wildfires burn trees and homes, harm wildlife, and spread harmful smoke into the air, which is dangerous to breathe and can affect air quality(质量) for miles. ( )1.
