1 The largest earthquake ever recorded was in Chile in 1960 with a magnitude of 9.5.
To form the superlative form of the adjective "large", we add "-est" to the end of the word, making it "largest". This is because we are comparing the earthquake to all other earthquakes recorded.

2 The earliest recorded earthquake was in China in 1177 BC.
To form the superlative form of the adjective "early", we also add "-est" to the end of the word, making it "earliest". This is because we are again comparing this earthquake to all other recorded earthquakes.

3 The deadliest earthquake happened in 1556 in China. About 830,000 people died.
To form the superlative form of the adjective "deadly", we drop the "y" and add "-iest" to the end of the word, making it "deadliest". This is because "deadly" ends in a consonant + "y" combination.

4 The deepest earthquake recorded occurred 450 km below the surface of the Earth.
To form the superlative form of the adjective "deep", we add "-est" to the end of the word, making it "deepest". This is because we are comparing the depth of this earthquake to all other recorded earthquakes.

5 Antarctica is the continent with the smallest number of earthquakes.
To form the superlative form of the adjective "small", we drop the "ll" and add "-est" to the end of the word, making it "smallest". This is because "small" ends in a consonant + "l" combination.

6 The most destructive earthquake ever recorded was in 1906 in San Francisco.
To form the superlative form of the adjective "destructive", we drop the "e" and add "-est" to the end of the word, making it "most destructive". This is because "destructive" ends in a consonant + "ive" combination.
