Here's why:
* Cinder cones are relatively small volcanoes formed by the accumulation of loose, pyroclastic fragments (cinders) ejected from a single vent. They typically have steep sides and a bowl-shaped crater at the summit.
* Mount Tambora is a stratovolcano, also known as a composite volcano. It's a much larger and more complex structure built up by layers of lava flows, ash, and tephra.
Mount Tambora's shape is characterized by:
* A large, prominent summit caldera formed by the devastating eruption in 1815.
* Steep slopes that rise from a broad base.
* Multiple vents and lava flows that contributed to its formation over time.
Therefore, Mount Tambora's shape is far from a simple cinder cone. It's a massive and complex volcanic structure shaped by a long and violent history of eruptions.
