Answer
# Brief Explanations:
- For question 6: Yellowstone National Park is known for its large - scale volcanic features and is a caldera. A caldera is a large volcanic depression formed by the collapse of a magma chamber after a large - scale eruption.
- For question 7: Ultra - Plinian eruptions are extremely powerful and are most likely to result in large calderas due to the massive amount of magma emptied from the magma chamber, causing the overlying rock to collapse.
- For question 8: At a continent/ocean convergent plate boundary, subduction of the oceanic plate beneath the continental plate can lead to the formation of stratovolcanoes. Lahar flows are common products of eruptions of stratovolcanoes as they can be triggered by the interaction of volcanic ash with water.
- For question 9: The large volcanic eruptions at Yellowstone are thought to be due to the partial melting of the mantle. Mantle plumes rise through the Earth's mantle and cause partial melting when they reach the crust, leading to volcanic activity.
# Answer:
6. caldera
7. Ultra - Plinian
8. continent/ocean convergent plate boundary, stratovolcano, lahar flows
9. partial, mantle
