Earth's land surface is built up by a process called tectonic subduction.
Related Information:
This process occurs as one tectonic plate is subducted (slips under) another, while the subducting plate is elevated as it moves over the subducted plate. The subducted plate is most commonly a oceanic plate.

Magma reaches the Earth's surface through a process called volcanic eruption. This occurs when pressure builds up underground and forces the magma to flow and eventually break through the Earth's surface. Once the magma reaches the surface, it is then called lava.
magma moves up earth suface
from rocks being melted in the earths core, it then gets pushed up and the pressurre builds, the a volcanic erupiton takes place due to the pressure from the outer core/mantle, strange but true

Weathering, erosion, and deposition. Earth's surface could also be built up by volcanism.
weathering, erosion, deposition, and uplift
Volcanoes are essentially holes in the earths surface through which magma and lava can erupt. when pressure builds up below the earths crust, magma is then forced violently out of the volcanoes.

lava effects the earths surface by destroying it and building it up
pressure builds up in the earth and pushes the magma up to the surface.
