Task 1. Mark the sentences T (True) or F (False) (4 points) Tsunami
Tsunamis are a series of waves in the occan that create surges (60JILIIKE BOJILI) of water. These walls of
water can reach up to 100 fcct high and cause widespread destruction (paspymeine) when thcy reach shore
(6eper).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
carthquakes are common. Underwater landslides (011013111) 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 (sauiluta) against
tsunamis is carly warnings that allow people to evacuate arcas near the ocean.
