Se as calotas polares derretessem completamente, o dia se tornaria mais curto. Isso ocorre porque a massa de gelo nas calotas polares exerce uma força gravitacional sobre a Terra, o que faz com que o planeta gire mais lentamente. Com a perda dessa massa, a Terra giraria mais rapidamente, diminuindo a duração do dia. Portanto, a alternativa correta é a letra b) O dia se tornaria mais curto.
