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.

Explanation:
Earth's thin outer shell is broken into big pieces called tectonic plates. These plates fit together like a puzzle, but they're not stuck in one place. They are floating on Earth's mantle, a really thick layer of hot flowing rock.The edges of tectonic plates are called boundaries.Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. ... Earthquakes usually occur where two plates are running into each other or sliding past each other.
