Where are the major mid-ocean ridges located?
South Pacific Ocean
At what types of boundary do mid-ocean ridges occur quizlet?
Oceanic trenches and large mountain belts form at convergent boundaries. Mid-Ocean ridges occur at divergent plate boundaries.
What is the function of the Mid Oceanic Ridge quizlet?
Mid-ocean ridges are spreading centers, they are divergent plate boundaries where magma wells up from below, creating new oceanic crust. Ocean trenches form where crustal plates plunge back into the mantle. Thus, these long, narrow depressions are associated with convergent plate boundaries.
Is the name of the process by which new seafloor is generated at mid ocean ridges quizlet?
In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them.
What causes a mid ocean ridge to form quizlet?
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
What is a Mid Oceanic Ridge quizlet?
mid-ocean ridge. an undersea mountain chain where new ocean floor is produced at a divergent plate boundary. sonar. a device that determains the distance of an object under water by recording echoes of sound waves.
How are oceanic ridges involved in the movement of two continents quizlet?
In the ocean. Proposed the theory of sea-floor spreading. Hess created at mid ocean ridges which moves continents. As magma is thrust up and hardens forming new crust, the ocean floor on both sides of the mid-ocean ridge move outward carrying the continents along with them.
What aspect of mid-ocean ridges provides the mechanism that allows plate tectonics to occur?
Mantle convection drives plate tectonics. Hot material rises at mid-ocean ridges and sinks at deep sea trenches, which keeps the plates moving along the Earth’s surface.
What geologic features form when two oceanic plates collide?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
Which events are associated with convergent boundaries?
Effects found at a convergent boundary between continental plates include: intense folding and faulting; a broad folded mountain range; shallow earthquake activity; shortening and thickening of the plates within the collision zone.
What is an example of convergent boundaries?
Examples of Convergent Boundaries The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. The collision of this oceanic and continental plate was how the Andes Mountains were formed. Convergent boundaries can also form islands.
