The theory of plate movements that involves magma rising is known as the mantle convection theory. In this theory, heat from the Earth's core causes the mantle's semi-fluid rock to undergo convection currents, where hot magma rises towards the surface, cools, and then sinks back down. This movement drives the tectonic plates on the Earth's crust, leading to their movement, interactions, and the formation of geological features such as mountains and oceanic ridges.

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.
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.
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.

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.

the magma cools on the surface and eventually u get land
Columns of rising magma are known as magma chambers or conduits. They are vertical channels through which magma rises from the Earth's mantle towards the surface. These columns are key components in the formation of volcanic eruptions.

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.
Volcanoes are primarily caused by tectonic plate movements and the release of pressure from the Earth's mantle. Stress from these movements and pressure can lead to magma rising to the surface and resulting in volcanic eruptions. Other factors such as the composition of the magma and the presence of water and gases can also influence volcanic activity.
