<p>A crater is what you can see on the top of a volcano and the vent is the tube leading to the crater. Sometimes fissures on the volcano can make a secondary volcanic cone if a volcano is a long periodic one which allows the magma to go sideways where the resistance might be lower.

A vent opens through the side of a volcano, somewhere on its slopes. The crater (and neck) can seal itself up, solidify over a period of inactivity, then re-open anew nearby to form a new crater. Magma will more readily move through the interface between a solidified neck and surrounding ash matrix than it will through the center of a solidified neck alone.

A crater is what you can see on the top of a volcano and the vent is the tube leading to the crater. Sometimes fissures on the volcano can make a secondary volcanic cone if a volcano is a long periodic one which allows the magma to go sideways where the resistance might be lower.
