A convection current is caused by differences in "temperature".
<u>Option: A</u>
<u>Explanation:</u>
The convection current is the outcome of variations in temperature. Like hot substance which is less denser, it rises while cool material which is more denser, it sinks. It is this motion that produces circulating processes in the environment, in water and in the Earth's mantle identified as convection currents. When air heats up it increases in the atmosphere, enabling colder air to circulate in below. This air flow generates waves, together with the Earth spinning. In effect, winds produce surface waves over the ocean.

the Clipper Ship
Explanation:
A clipper was a type of mid-19th-century merchantsailing ship, designed for speed. Developed from a type of schooner known as Baltimore clippers, clipper ships had three masts and a square rig. They were generally narrow for their length, small by later 19th century standards, could carry limited bulk freight, and had a large total sail area. Clipper ships were mostly constructed in British and American shipyards, though France, Brazil, the Netherlands and other nations also produced some. Clippers sailed all over the world, primarily on the trade routes between the United Kingdom and China, in transatlantic trade, and on the New York-to-San Francisco route around Cape Horn during the California Gold Rush. Dutch clippers were built beginning in the 1850s for the tea trade and passenger service to Java.[
