Magma rises to the Earth's surface through volcanic eruptions via conduit or lava channels within the Earth's crust. The buoyant force of the magma, caused by the difference in density between the magma and surrounding rocks, helps drive its upward movement. As the magma rises, it can also accumulate in magma chambers beneath the surface before erupting as lava.
The opening in Earth's crust through which magma rises to the surface is known as a volcano.
Before magma can rise to the surface, it must first be generated through melting of the Earth's mantle or crust. This melting can be caused by an increase in temperature, a decrease in pressure, or the addition of volatiles. Once magma is generated, it can rise towards the surface through fractures and conduits in the Earth's crust.
Volcanoes occur when magma from within the Earth's mantle rises to the surface, creating pressure that eventually leads to an eruption. The magma can come from melting of the Earth's crust or mantle. When the pressure becomes too great, the magma breaks through the Earth's surface, forming a volcano.
Rocks become less dense when they melt
An opening in the Earth's crust that allows magma to reach the surface is called a volcano. Volcanoes can be found along tectonic plate boundaries where the Earth's crust is weak, allowing magma from the mantle to rise and erupt onto the surface.

Melted rock beneath Earth's surface is known as magma. Magma forms in the Earth's mantle and can rise to the surface, where it is then called lava. Magma can also cool and solidify beneath the surface, forming igneous rocks.

because of the high pressure
Rocks become less dense when they melt
Magma rises because it is less dense than the rock around it.
Magma rises towards the Earth's surface due to differences in density between the magma and surrounding rock, as well as pressure changes. This movement can eventually lead to volcanic eruptions.
The rock that melts underneath the Earth is called magma. Magma is formed from the melting of the Earth's mantle and can rise to the surface to form igneous rocks when it solidifies.
