False
Greed and money. The Deepwater Horizon was in need of repairs and needed new machinery, but BP executives stressed how behind on drilling they already were and told them to keep pushing on. Its BP's and the owners of the Deepwater Horizon's Fault.

This process creates a type of current known as thermohaline circulation. The sinking of saltier, denser water drives a deep, slow-moving current, while the rising of less salty water leads to surface currents. Thermohaline circulation is important for distributing heat and nutrients in the ocean.
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.

The two forces acting on a sinking object are gravity, pulling the object downward, and buoyancy, pushing the object upward. Buoyancy force is caused by the displaced fluid pushing back against the object's weight, resulting in the object sinking, floating, or rising depending on the balance between these forces.
If you are referring to the Deepwater Horizon desaster, the answer is no.

All currents are caused by differences in pressure.
The movement of the pen could have been caused by someone physically pushing or dropping it, an external force such as air currents or vibrations, or a change in the pen's environment like a sudden change in temperature.
They are similar because if you think about it carefully, the ocean currents are caused by the air currents and the air currents are caused by the ocean currents, so, it is all a scientific cycle.
