Natural disasters like floods, droughts, earthquakes, and tsunamis can cause significant damage. Floods occur due to heavy rainfall and overflowing rivers, affecting homes, farms and infrastructure. Droughts happen when there is not enough rain over long periods, drying up land and crops. Earthquakes are caused by the movement of tectonic plates underground, sometimes resulting in collapsed buildings and injuries. Tsunamis are large sea waves triggered by underwater earthquakes that can destroy coastal areas when they crash onto land. Governments provide relief efforts like food, water, shelter and medical aid to help communities recover from these disasters.
