Why does sea floor spreading have to happen in the sea?
Because of plate tectonics. Because it's 2 plates underwater that are moving apart. Magma rise up to where the 2 plates are separating to fill in the gap. Seafloor spreading occurs underwater.
Boundary between two plates that are moving apart?
Convergent: plates move into one another.Divergent: plates move apart.Transform: plates move sideways in relation to each other.
What is the stress force that pulls on the crust where two plates are moving apart?
it may be gravity
The stress force that pulls on the crust where two plates are moving apart is called .?
tension
Where is most of the earths new crust found?
Most of Earth's new crust is found along mid-ocean ridges, underwater mountain ranges where tectonic plates are moving apart. This is where magma rises from the mantle to create new crust through volcanic activity.
What are volcanoes and what causes them?
a volcano is a rupture or opening in the earths crust. caused by convergent (coming together) or divergent (moving apart) plates
Do Earths Tetonic plates move apart?
Yes they do.
Do trenches occur where plates are moving apart?
Trenches form where plates are moving towards each other in a convergent plate boundary, not where they are moving apart. At divergent boundaries, such as mid-ocean ridges, plates are moving apart, creating new crust.
Why does a volcano form at the boundary of two plates moving apart?
A volcano will form at the boundary of two plates moving apart. This is because the two plates moving apart create a crack allowing molten lava to flow up from the mantle.
Are the earths countries moving further apart?
No the continents are.
Plates move apart because of?
plate tectonics, which is the movement of the Earth's lithosphere. This movement occurs due to the convection currents in the Earth's mantle, causing plates to gradually shift and separate from each other. The process of seafloor spreading at mid-ocean ridges is a common example of plates moving apart.
What occurs when tectonic plates move apart?
A rift valley.
Why is the Atlantic expanding?
The Earths plates are constantly moving, and changing causing different landmasses and occurrences to happen such as earthquakes. Our earth is always changing in size. Straight, short Answer: It is because of the movement of the Earths plates constantly changing and shifting.
Is spreading sea plates pulling apart?
Yes, spreading sea plates are moving away from each other due to the process of seafloor spreading, which occurs at mid-ocean ridges. This movement allows magma to rise from the mantle, creating new crust and pushing the existing plates apart.
At the Mid-Atlantic Ridge plates are moving apart at about what rate?
At the Mid-Atlantic Ridge, plates are moving apart at a rate of around 2.5 centimeters per year. This movement is driven by seafloor spreading, where magma rises from the mantle and solidifies to create new crust, pushing the plates apart.
Sea-floor spreading occurs in places where two plates are doing what?
Sea-floor spreading occurs in places where two tectonic plates are moving away from each other. Magma rises to the surface, creating new crust as the plates separate. This process is a key mechanism driving the movement of Earth's lithosphere.
Which force occurs where earth plate are moving apart?
what
