Answer:
Convection currents flow due to variations in the temperature and salinity in seawater, both of which influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.

Explanation:
The correct answer is - it's mass.
Jupiter is the biggest planet in our Solar System, but only the biggest, also it has the biggest mass by far from all the planets. Because of its very big mass Jupiter has a very strong gravitational pull. The strong gravitational pull contributes to the attraction and keeping of lots of bodies that can not escape it, instead they revolve around the planet. These objects, or space bodies, that the gravitational pull of the planet managed to trap, became the moons, or rather natural satellites, of Jupiter.
