A crater that becomes very large as a result of the collapse of its walls is called a caldera. Calderas are typically formed after a volcanic eruption when the magma chamber empties and the summit collapses into the void below.
Crater Lake formed after the collapse of Mount Mazama.
It was formed by the collapse of the volcano Mount Mazama.
This is known as a Caldera.
No, Crater Lake was formed by the collapse of a volcano known as Mount Mazama. Around 7,700 years ago, a massive eruption caused the volcano to collapse into itself, creating a caldera that eventually filled with water to form what is now Crater Lake.
Volcanic crater.
This is a crater
This is known as a caldera or a crater.
This type of geological feature is known as a caldera, formed when the magma chamber beneath a volcano empties, causing the volcano to collapse inward. Calderas can be several kilometers in diameter and are often characterized by steep walls and a flat floor. Examples of calderas include Yellowstone in the United States and Santorini in Greece.
The Bailly crater on the Moon was most likely formed by the impact of a large asteroid or comet colliding with the lunar surface. The impact would have created a crater with a central peak and terraced walls, features commonly seen in larger impact craters. Bailly crater is one of the largest craters on the Moon and is estimated to have formed billions of years ago.
Crater Glacier formed in the crater left by the 1980 eruption of Mount St Helens. The glacier formed between the crater's south wall and the cooled lava dome in the middle. The high walls of the crater keep the southern part of the crater in almost perpetual shade. Without sunlight, this location remains cool and so the snow that falls there never completely melts. Over the course of a few years this snow has piled up to form a glacier.
A circular basin surrounded by mountains is typically referred to as a crater or caldera, depending on whether it was formed by volcanic activity or by the collapse of a volcanic cone.
