Seafloor spreading typically occurs at rates between 2.5 to 10 centimeters per year. However, in some places such as the East Pacific Rise, spreading can happen much faster, up to 15 centimeters per year.

What is the primary force that cause the seafloor to spread and continental to drift?

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.


What was the primary force that causes the seafloor to spread and continents to drift?

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.


How does the process of seafloor spreading occur with two tectonic plates moving away from each other?

Seafloor spreading happens when two tectonic plates move apart. Magma rises up from the mantle through the gap, creating new oceanic crust. As the plates continue to move apart, the new crust pushes the older crust away, causing the seafloor to spread.


How has knowledge of mid-ocean ridges changed as a result of evidence for sea-floor spreading?

Before the discovery of seafloor spreading, mid-ocean ridges were thought to be static features. However, with evidence for seafloor spreading, it was realized that new oceanic crust is forming at mid-ocean ridges, pushing older crust away and causing the seafloor to spread apart. This discovery fundamentally changed our understanding of plate tectonics and the geologic processes happening at mid-ocean ridges.


What happens when 2 tectonic plates spread apart?

When two tectonic plates spread apart, it creates a divergent boundary where new crust is formed as magma rises and solidifies between the plates. This process leads to seafloor spreading and the formation of features like mid-ocean ridges.
