the magma cools and hardens and then it becomes the surface of around the volcano like a rock land
A volcanic vent.
A bowl-shaped depression that forms around the vent of a volcano is a crater. These craters can be formed by the explosion of volcanic material or the collapse of the volcanic cone following an eruption.
A bowl-shaped area that forms around a volcano's central vent is called a crater.
No, it forms a volcano.
The opening at the top of a volcano is called the "vent." This is where magma, gases, and ash escape from the volcano during an eruption. The vent may lead to a larger crater, which is the bowl-shaped depression that forms around the vent after eruptions.

Lava is spewed out of a vent like a cannonball, forming a cone-shaped volcano.
It forms by volcanic activity in the vent of a volcano.

If the volcano is active, there may be vents around the volcano as well as on top. A vent is where volcanic material (lava, steam, ash) is being released.
