magma
An opening in the Earth's surface through which lava can flow is called a volcano. When pressure builds up beneath the Earth's crust, it can force magma to erupt through a vent in the form of lava, gases, and ash.
A volcano or volcanic vent is an opening in the earth's surface that allows melted rock (lava) to flow out.

Magma once it reaches the earths surface is called lava.

lava effects the earths surface by destroying it and building it up
When magma reaches the Earth's surface, it is called lava. Lava can flow out of a volcano during an eruption and can cool to form igneous rocks. The characteristics of the lava, such as its temperature and composition, can influence the type of volcanic eruption that occurs.
Lava is molten rock. The rock deep inside the earths mantle is always molten, and when it occasionally breaks through to the surface, the opening is called a volcano, and the liquid rock spilling out of the top is lava.
Magma that reaches earth's surface is called lava.
