Océano Atlántico

Nuria is on a small boat near Cádiz with her uncle and wants a drink. The seawater is salty, so she cannot drink it. Rivers carry minerals from rocks to the sea, the water evaporates, and the salt stays. The Atlantic separates the Americas from Europe and Africa. It is the second largest ocean; only the Pacific is larger. A dolphin jumps. Humpback whales in the Atlantic sing underwater, but they do not see one today. The Gulf Stream carries warm water toward northern Europe, and winters on that coast are less cold than in other lands equally far north. The story does not treat that current as the reason for the heat in Cádiz. Icebergs sometimes float in the North Atlantic, and near the equator the water is warm and many fish live there. Vikings crossed from Europe to America. Large ships carry big boxes. Nuria keeps a plastic bottle on the boat because plastic trash harms sea animals. She returns to Cádiz with fresh water.
