multiple choice question
what is an opening in earths crust through which lava erupts and flows out onto earths surface?
o vent
o conduit
o fissure

Explanation:

A vent is an opening in the Earth's crust through which lava erupts and flows out onto the Earth's surface. A fissure is a long, narrow crack or opening in the Earth's crust. A conduit is a passage or channel through which magma travels from the magma chamber to the surface. Since the question asks for an opening through which lava erupts and flows out, the key characteristic here is the opening for lava eruption, which is best described by the term "vent".

Answer:

vent
