Mid-Ocean ridges are places where tectonic plates are doing what?

The Atlantic mid ocean ridge is where the seafloor is pulling apart. The ridge is formed by the magma beneath the seafloor shooting up and quickly cooling and hardening.

Where two tectonic plates meet?
two tectonic plates meet usually at mid ocean ridges (eg Iceland) and at destructive plate boundaries (eg Japan).
Why do oceanic rises and oceanic ridges exist?
They are located at spreading centers in the middle of the ocean. As tectonic plates move apart, magma fills it in and creates ridges and rises which are essentially mountain chains.
How does the force of gravity affect tectonic plates?
Gravitational sliding:Plate motion is driven by the higher elevation of plates at ocean ridges. As oceanic lithosphere is formed at spreading ridges from hot mantle material it gradually cools and thickens with age (and thus distance from the ridge).
Do Plates move together or apart at mid ocean ridges?
Mid Ocean ridges separate the plates and create new seafloor. Places where plates converge and disappear into the abyss are called trenches. The Marianas Trench is the deepest trench in the world.
What is formed when crustal plates move toward each other?
when tectonic plates move toward each othe forms
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
What was discovered that led to the knowledge that tectonic plates exist?
Mid-ocean ridges and trenches
What are the differences between ocean ridge and seamount?
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
Where two tectonic plates meet?
two tectonic plates meet usually at mid ocean ridges (eg Iceland) and at destructive plate boundaries (eg Japan).
Where are the midocean ridges offset the most by faults?
At transform faults or transform zones.
Examples of constructive forces?
Volcanoes, Deposition, Tectonic Plates (Constructs various landforms), erosion, and mid ocean ridges
Why are tilted blocks of rock common along mid-ocean ridges?
Plates move apart at these tectonic plate boundaries.
Underwater mountains chains that forms where two tectonic plates are pulling are called?
Underwater mountain chains that form where two tectonic plates are pulling apart are called mid ocean ridges. The largest is the Mid Atlantic Ridge.
Where can ignoeus rock be found?
Igneous rocks form only in certain places. Fractionation occurs mostly where tectonic plates are either moving apart at mid ocean ridges or pushing together at subduction zones.
Where does the movement of plates take place?
Every place on earth is on a tectonic plate as the earth crust consists of tectonic plates. And every tectonic plate is constantly in motion (as they float on magma, beneath the crust). Places which suffer most of earthquakes are in between two tectonic plates. an example of such a place is the City of Los Angeles in California. Mid Oceanic ridges and rifts and mountains are also results of plate tectonics.
What causes openings in the surface of the earth?
The shifting of tectonic plates which cause sea-floor spreading which is located in mid-ocean ridges.
What is located in midocean ridges?
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
