Summative assessment for the unit
Task 1. Reading. 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.
