Which theory of plate movement involves magma rising all the way from the lower mantle to spread the plates apart?
The theory of plate movement that involves magma rising from the lower mantle to spread the plates apart is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma wells up and solidifies, pushing the plates apart in opposite directions.
Which theory of plate movement involves magma rising all the away from the lowrer mantle to spread apart plates?
The theory of plate movement that involves magma rising all the way from the lower mantle to spread apart plates is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma ascends and solidifies, pushing the plates apart.
Which theory of plate movement involves magma rising all the way from the lower mantle to spread apart plates A.Slab-push?
The theory of plate movement that involves magma rising from the lower mantle to spread apart plates is known as "mantle convection." In this process, hot, less dense magma rises towards the surface, causing tectonic plates to move apart at divergent boundaries. This rising magma creates new oceanic crust, facilitating the movement of plates. Slab-push, on the other hand, is associated with the downward movement of a tectonic plate at a subduction zone.
Which theory plate movement involves magma rising all the way from the lower mantle to spread?
The theory that involves magma rising from the lower mantle to spread is known as "mantle plume theory." This theory suggests that hot, buoyant magma, or mantle plumes, originates deep within the Earth, potentially near the core-mantle boundary. As these plumes rise, they can create hotspots that lead to volcanic activity and contribute to the movement of tectonic plates at the surface. This process is distinct from the more commonly known plate tectonics driven by the movement of lithospheric plates over the semi-fluid asthenosphere.
Which theory plate movement involves magma rising all the away from the lowrer mantle to spread apart plates?
The theory of plate tectonics explains that plate movement involving magma rising from the mantle to spread apart plates is known as seafloor spreading or mid-ocean ridge spreading. This process occurs at divergent plate boundaries where two plates move away from each other, creating new oceanic crust as magma rises and solidifies at the mid-ocean ridges.

Most geologists thinks that the movement of earths plates is caused by?
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.

What caused the continental plate to move?
The movement of continental plates is primarily driven by the process of plate tectonics. This involves the convection currents in the Earth's mantle, which cause the plates to move over the semi-fluid asthenosphere. As these currents transfer heat within the mantle, the plates are dragged along and either spread apart, collide, or slide past each other, leading to various geological phenomena such as earthquakes, volcanic eruptions, and the formation of mountains.
What is it called when the earth's plates spread apart?
When Earth's plates spread apart, it is known as seafloor spreading. This process occurs at mid-ocean ridges where new crust is formed as magma rises up from the mantle and solidifies. As the plates move apart, they create new oceanic crust.
Plate movement is thought to be caused by convection currents in the?
Earth's mantle. Heat from the core causes magma to rise and spread beneath the lithosphere, creating convection currents that push tectonic plates in different directions. As plates move, they interact at boundaries, leading to various geological phenomena such as earthquakes and volcanoes.
What process causes earths plates to move?
The process of 'earth plates moving' is Alfred Wageners theory of continental drift. This theory proposes that convenction currents in the earths mantle provides a 'cushion' on which the plates can move.
