Sea floor spreading occurs at mid-ocean ridges where magma rises to create new oceanic crust. As the crust forms, it pushes the existing plates on either side away from the ridge, causing the plates to move. This process helps explain the movement of tectonic plates and how they interact with each other on Earth's surface.

What is it called when two oceanic plates move apart and new crust is formed?
This process is called seafloor spreading. As the two plates move apart, magma rises from the mantle to create new crust at the mid-ocean ridge. This process helps explain the movement of Earth's tectonic plates and the reshaping of the ocean floor.
Where does seafloor spreading take place?
Mid-Ocean ridges.
What is the definition of plate tectonic movement?
Plate tectonic movement refers to the horizontal and vertical movement of the lithosphere plates that make up the Earth's surface. These plates float on the semi-fluid asthenosphere underneath, and their movement is responsible for shaping the Earth's surface through processes like seafloor spreading, subduction, and continental drift.
What kind of activity causes seafloor spreading?
Seafloor spreading is caused by the movement of tectonic plates away from each other at mid-ocean ridges. As the plates separate, magma rises to the surface, solidifies, and creates new oceanic crust. This process is part of the theory of plate tectonics.
What is the movement called when the seafloor divided where the two plates moved from each other?
The movement you are referring to is called seafloor spreading. It occurs at mid-ocean ridges, where two tectonic plates move apart from each other, causing magma to rise and solidify, creating new oceanic crust.
What is the therory that explain the movement of tectonic plates?
Continental drift
How does the movement of tectonic plates and continents relate?
When the plates drift apart through sea floor spreading, so do the continents
How might geologic events such as the movement of tectonic plates affect the environment where species live?
Movement of tectonic plates can cause seafloor spreading and reversal of Earth's magnetic field, which can affect the organisms that are not adapted to the geological enviroment.
Earthquakes occur mainly allong the edges of?
Tectonic plates and fault lines created by the movement of tectonic plates.
Can volcanoes be cause by spreading tectonic plates?
no
What plates causes mount saint Helen to form?
Tectonic movement in the ocean or sfs sea-floor spreading, caused it

What does the spreading of tectonic plates cause?
Spredading of tectonic plates causes Tsunamis, Earthquakes, Volcanic erruptions, etc.
How are seafloor spreading and continental drift related?
Seafloor spreading is a key component of the theory of continental drift. As new oceanic crust forms at mid-ocean ridges during seafloor spreading, it pushes the existing crust outward on both sides of the ridge. This movement can help explain how continents have shifted positions over time due to the movement of tectonic plates.
