What is the vent and crater?

A crater is visible on the top of a volcano, and the vent is the tube that leads to the crater. If the volcano has a lengthy period, fractures on the volcano can generate a secondary volcanic cone, allowing magma to flow sideways where resistance is lower. This area of the planet contains many large volcanoes, most notably Hawaii.

The word "volcano" comes from the Latin word volans, meaning "flying". Volcanoes are characterized by their sphericity and their ability to eject material into the air. Some volcanoes such as Mount St. Helens have had their tops blown off while others, like Mauna Kea, do not have a solid surface but rather an extremely steep slope. The shape of a volcano is determined by its underlying cause: if it's an underwater volcano or an island volcano. Underwater volcanoes tend to be more spherical than island volcanoes because there is no force acting on their sides so they can drift in space until they collapse under their own weight. Island volcanoes, on the other hand, are usually less symmetrical because of the influence of wind and water. They may also appear flatter due to erosion caused by rain and snow.

Volcanoes are defined by the type of rock they produce. Composite volcanoes contain two main types of rocks: lava flows and cinder cones.

What do you call a deep hollow or vent at the top of a volcano?

Secondary vents form as the magma increases. Those secondary ones are simply tiny branches from the main tube. A crater is located at the volcano's highest peak. A caldera is a feature of various volcanoes. When a volcano becomes hollow and eventually falls on itself, a caldera emerges.

A caldera is an area where a volcano has collapsed into itself, forming a depression full of debris that can reach a height of more than 1312 m (4300 ft) above sea level. The word comes from Spanish caldera, which in turn comes from Latin Calvus meaning "empty" or "void". Calderas are usually formed when large amounts of lava flow out of one or more openings in the side of a volcano.

They can be very dangerous because all that hot gas and lava inside the caldera may blow out at any time with no warning. This can happen if the volcano suddenly decides to erupt again. The gas released during an eruption can travel great distances and cause damage over a large area. The largest known volcanic caldera on Earth is that of Nyiragongo, which forms a crater within a larger plateau complex in Rwanda. It is about 30 miles (50 km) in diameter and reaches depths of up to 1421 meters (4600 feet) below the surface.

What do you call a basin-like depression above a cone vent?

A crater is a basin-like depression at the summit of a volcano's cone. The word comes from the Latin word for bowl, calix, because the area looks like an old crater site. Craters are usually less than 100 meters (330 feet) in diameter, but some can be several kilometers (miles) across. They often show evidence of explosive eruptions or collapse of large parts of the volcano's dome.

Craters can also form where there was no explosion; instead, the hole forms when the volcano collapses into it. These craters are called "impact" craters and can be very large. One example is the Moon where many impact structures are visible.

Finally, some craters are not on volcanoes but inside Earth's crust. These include the deep craters found on planetary surfaces and those formed by meteorites.

The word "basin" is used here to describe an area where lava flows out of a volcanic vent and forms a circle or near-circular shape. There may be one or more cones rising up from the center of the flow. If there is only one cone, then it can be either flat-topped or has a slight rise at its top.
