This question has a cascade of answer, that is the primary answer induces a secondary question that in turns induces other questions.
The primary force that motivates seafloor drift is rising magma at the ocean rifts. As the magma rises it flows off to the side (volcanos can only get so high before their vertical weight stops further rising and forces basal magma off to the side.)
Why does magma rise?
Magma rises because it is hot and fluid. Hot ANYTHING is less dense than cold ANYTHING and will float up.
Why is magma hot?
The material at the earth's core contains unstable neucleotides (unstable neucleotides are everywhere) and when they decay they release heat. Being at the Earths core this heat has no where to go. The mass of the earth above it is like a huge insulating blanket so the centre of the earth keeps its heat and gets hotter and hotter until the rock at the core turns into magma and floats up.
Primary Koch Infection is also known as Tuberculosis. It is caused by the bacteria Mycobacterium tuberculosis and is very contagious. It is spread when the person with the infection coughs or sneezes.
A hoaxer causes people to spread a made-up story that they believe is true.
An epidemiologist is a person who studies or investigate the causes, development, and spread of diseases.
The process you're thinking of is called "diffusion". It is the property of a substance to travel from a place of greater concentration to a place of lessen concentration. Put simply, a substance will spread itself out in whatever area it's contained in. The effect this has on the smelly gas in the room is that the gas will go from the area of greater concentration (Where the gas was released) to lesser concentration (The rest of the room). Thus, the gas will spread out evenly amongst the air in the room.
In a statistical sense, spread, otherwise known as statistical dispersion, is one of various measures of distribution.
Geothermal Drift.
thermal convection
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.
The primary force that causes the seafloor to spread and continents to drift is plate tectonics. This process is driven by the movement of molten rock in the Earth's mantle, which generates forces that push apart tectonic plates, leading to seafloor spreading and continental drift.
In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.

Radiologyinfotation
The primary force behind seafloor spreading and continental drift is convection currents in the Earth's mantle. These currents move the tectonic plates above them, causing them to either spread apart or collide. The spreading of seafloor and the shifting of continents are part of the larger process of plate tectonics.

The primary force that causes the sea floor to spread and continents to drift is called "plate tectonics." This geological process involves the movement of the Earth's lithosphere (made up of tectonic plates) on the semi-fluid asthenosphere below, driven by convection currents in the mantle.
