Disasters are events that cause serious harm, damage, or loss of life. They can happen naturally, like earthquakes and hurricanes, or they can be man-made, like oil spills or fires. Learning vocabulary related to disasters can help TOEFL students understand passages about natural events, emergency responses, and environmental challenges.

Understanding vocabulary related to food crops is important for students preparing for the TOEFL exam, as it can help them understand passages and discussions about agriculture, biology, and the environment.
