The steep walled depression surrounding a volcano vent is called the crater. In dormant volcanos, these may fill with water and become crater lakes.

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.


What is a volcano called that looks like a depression in the ground called?

A volcano that looks like a depression in the ground is called a caldera. It forms when the summit of a volcano collapses following a massive eruption, creating a large crater-like depression. Calderas can range in size from a few kilometers to tens of kilometers in diameter.

Caldera.


What is the large hole at the top of a volcano called?

The large hole at the top of a volcano is called a "crater." It is formed when explosions or collapses create a depression at the summit of the volcano.

You are possibly looking for Caldera.


What is the opening of the top of a vocano called?

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.

Volcanic crater.


What is saucer shaped depression at mouth of volcano called?

A saucer-shaped depression at the mouth of a volcano is called a volcanic caldera. Calderas are formed when a volcano collapses into the emptied magma chamber below, creating a large, basin-like crater.


What is the crater in a volcano?

Any place the volcano opens up is called a vent since it allows for the release of built up heat and gas. The main summit of the volcano is usually called the crater but I'm guessing there is probably something more technical that a geologist would call it. Hopefully this helps.


What is the bowl shaped area around a volcanos central vent is called?

The bowl-shaped area around a volcano's central vent is called a crater. Craters are formed by explosive volcanic activity that creates a depression at the summit of the volcano. They can vary in size and shape depending on the eruption and the type of volcano. Some craters may also fill with water, forming a crater lake.


What is the mouth of a volcano called?

The mouth of a volcano is called the "vent." This is the opening through which volcanic materials, such as lava, ash, and gases, are expelled during an eruption. Vents can vary in size and may occur at the summit or along the sides of the volcano. In some cases, the vent can lead to a crater, which is a bowl-shaped depression formed around the vent.
