Rigid plates are spreading centres or rift zones are where tectonic plates are moving away from each other. Often these areas are in ocean basins. The Mid-Atlantic Ridge is where the North and South American plates are moving away from the Eurasian and African plates. Magma wells up to fill the void left by the plates, forming a ridge. The Mid-Atlantic Ridge is the longest mountain chain on earth. Rift ones sometimes extend onto land. The Dead Sea/Jordan River valley is one example. Another area is in eastern Africa.
What else can I help you with?
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.
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.
Large crustal plates moving on the earth's surface are?
called tectonic plates. These plates can move in different directions, either colliding, moving apart, or sliding past each other. Their movement is responsible for phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
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 does moving of techtonic plates cause?
Moving of tectonic plates causes earthquakes, volcanic activity, and the formation of mountain ranges when plates collide or pull apart. These movements also contribute to the creation of ocean basins and continents over long periods of time.
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.
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.
How do valcanos form?
two plates moving apart on a hot spot
How are plates moving at diverging boundaries?
To diverge means to move apart.
What is boundaries between two plates that are moving apart?
divergent boundary
What is the difference between convergent boundary and convergent plate boundary?
Convergent means where plates are moving together. Divergent means where plates are moving apart.
What happens when two continental plates?
If the plates are moving together from opposite directions, the colliding edges will uplift into mountain ranges. If the plates are moving apart, a rift valley will form. If the plates are moving together at oblique angles, a fault zone will occur.
What rate are the plates moving at the mid Atlantic ridge?
The mid Atlantic Ridge plates are moving apart at approximately 2.5 to 3 centimeters per year.
What is is the boundary when two plates that are moving apart?
It is called a divergent plate boundary.
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
