One of these events is a hurricane. A hurricane is a violent storm with strong winds and heavy rains. Hurricanes are the largest and most powerful of storms. They begin over oceans. Hurricane winds move in a circular pattern at speeds of 75 miles per hour or more.
Most hurricanes die out far from land.
Hurricanes that move toward land act like giant bulldozers. Strong winds and giant waves damage or destroy almost everything in their path. Trees are uprooted. Lives are often lost. Another event that causes sudden changes to Earth's surface is an earthquake.
