Question

when did Tsunami happens class 8

Answer 1

Sumatra is an island in Southeast Asia that is part of the Sunda Islands. Sumatra has a wide range of plant and animal species but has lost almost 50% of its tropical rainforest in the last 35 years[clarification needed]. Many species are now critically endangered, such as the Sumatran ground cuckoo, theSumatran tiger, the Sumatran elephant, the Sumatran rhinoceros, and the Sumatran orangutan. Deforestation on the island has also resulted in serious seasonal smoke haze over neighbouring countries, such as the 2013 Southeast Asian haze causing considerable tensions between Indonesia and affected countries Malaysia and Singapore.[1]
