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.
Theory of plate tectonics explains how forces deep within earth can cause ocean floors to spread and continents to move
the spred of bactriea is caused by sickness
Isolation of a child with measles belongs to the secondary level of prevention, which aims to reduce the impact of a disease that has already occurred by limiting its spread to others.
They are spread apart now because before the were one big landmass.
Geothermal Drift.
thermal convection is the primary force that cause the sea floor to spread

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.
In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.
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.
Convection currents
the primary force that causes the seaffloor to spread and contienents to drift
it is spread across 2 continents of Asia and Europe.
Primary complex is another term that refers to tuberculosis. Tuberculosis is an airborne disease that is spread through coughing, talking, sneezing and breathing.
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.
