Summary

[edit]
Description
English: A caldera is a large, usually circular volcanic depression formed when magma is withdrawn or erupted from a shallow underground magma reservoir. It is often difficult to visualize how calderas form. This simple experiment using flour, a balloon, tubing, and a bicycle pump, provides a helpful visualization for caldera formation.
Українська: Кальдера — це велике, зазвичай кругле вулканічне заглиблення, що утворюється внаслідок витягування або виверження магми з неглибокого підземного резервуара магми. Часто важко уявити, як утворюються кальдери. У відео простий експеримент з використанням борошна, повітряної кульки, трубки та велосипедного насоса забезпечує корисну візуалізацію, яка допомагає пояснити утворення кальдери.
