Чёрное золото
Нефть используется для многих вещей. Его иногда называют Чёрное золото, потому что это очень ценно. Нефть производится из растений и животных, которые жили миллионы лет назад. Это глубоко в земле. Люди копают нефтяные скважины, чтобы вытащить нефть из-под земли. Нефтяные вышки используются для добычи нефти из-под моря. Мы используем все больше и больше нефти каждый год.
