Reading Task 1. Read the text and do the task
Tsunamis are a series of waves in the ocean that create surges of
water. These walls of water can reach up to 100 feet high and cause widespread
destruction when they reach shore. Earthquakes on the sea floor are the usual
cause of tsunamis. When the ocean floor at a plate boundary raises or falls, it
displaces water and sends rolling waves that become a tsunami. Around 80
percent of tsunamis happen in the so-called "Ring of Fire" in the Pacific Ocean.
This is a volcanically active area were tectonic plate shifts and earthquakes are
common. Underwater landslides and volcanic eruptions can also start tsunamis.
In Earth's ancient past, tsunamis were caused by a meteorite crashing into the
ocean. People's best defense against tsunamis is early warnings that allow
people to evacuate areas near the ocean.
