How do the mantle's convection currents move to form a mid-ocean ridge?
The mantle's convection currents move in the mantle in the form of magma which creates the mid-ocean ridge. Mid-ocean ridges are found in every ocean in the world and when the currents erupt as lava the eventually cool and create a crust.
What are the three processes that cause tectonic plates to move?
Three processes that contribute to the motion of tectonic plates are convection currents, ridge push, and slab pull. Convection currents is when the mantle rises, cools, sinks and heats, then rises and repeats the cycle. Ridge push is a gravitational force that causes a plate to move. Slab pull is the movement of tectonic plate lithosphere due to convection currents in the asthenosphere.
Where is a mantle convection current most likely to move upward?
A mantle convection current is most likely to move upward at divergent plate boundaries such as mid-ocean ridges. Here, the heat from the Earth's interior causes the mantle material to rise, creating new crust as it cools and solidifies.
What motions help move the plates?
The primary motions that help move tectonic plates are convection currents in the Earth's mantle, slab pull, and ridge push. Convection currents occur when hot mantle material rises and cooler material sinks, creating a cycle that drives plate movement. Slab pull occurs when a denser oceanic plate sinks into the mantle at a subduction zone, pulling the rest of the plate along with it. Ridge push happens at mid-ocean ridges, where new material pushes older material away as it cools and solidifies.
What is a force that is causing the plates to move at a midocean ridge?
friction - convection currents in the mantle drag the plates away from the hot rising zone below the ridgegravity - gravity pulls down on the cold dense plate being subducted under the continent, dragging the plate away from the ridge

Which cross sectional diagram of a portion of the crust and mantle best shows the pattern of mantle convection currents that are believed to cause the formation of a mid ocean ridge?
A diagram showing circular convection currents rising from the mantle beneath a mid-ocean ridge would best illustrate the pattern of mantle convection believed to cause ridge formation. This would demonstrate how hot mantle material rises, spreads horizontally along the base of the lithosphere, and then sinks back down as it cools, driving the movement of tectonic plates and the creation of new seafloor at the mid-ocean ridge.
What are the three forces that drive plate motion?
The three forces that drive plate motion are mantle convection, ridge push, and slab pull. Mantle convection involves the movement of material in the Earth's mantle, while ridge push is the force exerted by the elevated mid-ocean ridges. Slab pull is the force generated by the sinking of cold, dense oceanic lithosphere into the mantle at subduction zones.

What are 3 forces that causes tectonic plates to move?
This will be in detail for your information. 3 driving forces of plate motion...one plate moves underneath the other or a continental collision (if the 2... cause the gravitational sliding of lithosphere plates away from them...
What kind of currents inside the earth drive plate motion?
The main driving forces of plate motion are mantle convection currents and ridge push. Mantle convection currents are caused by the heat generated from the core creating movement in the mantle. Ridge push occurs at mid-ocean ridges where new crust is formed and pushes older crust away. These currents create the movement of tectonic plates on the Earth's surface.
The sinking of cold ocean lithosphere drives the motions of mantle convection through?
The sinking of cold ocean lithosphere drives mantle convection by creating a negative buoyancy force that pulls the lithosphere into the mantle. This movement displaces hotter, less dense material in the mantle, initiating a cycle of convection currents. These currents drive plate tectonics and heat transfer within the Earth's interior.
Where is a mantle convection current most likely to move upward?
A mantle convection current is most likely to move upward at divergent plate boundaries such as mid-ocean ridges. Here, the heat from the Earth's interior causes the mantle material to rise, creating new crust as it cools and solidifies.
What drives movement of the plates?
Convection currents in the mantle drive plate movements.
What three mechanisms may drive tectonic plates to move?
Convection, the heating and cooling of the astenosphere, a ridge push, at mid ocean ridges oceanic lithosphere slides down due to gravity, slab pull, oceanic lithosphere sinks in the astenosphere and pulls the rest of the tectonic plate with it.
What is the difference between a ridge board and a ridge beam?
A ridge board doesn't support rafters of the bridge whereas a ridge beam does.
What is the difference between a ridge and a rift?
A rift is a crack or space.A ridge is a range of hills.
