What is a Cone Volcano?
200
What characteristic of stratovolcanoes contributes to their distinctive appearance, featuring steep slopes and a conical shape?
What is the alternating layers of lava flows, volcanic ash, and pyroclastic materials?

What is this could emerging from this cone volcano made of?
What is ash?
200
What term describes the molten rock expelled during a volcanic eruption from a shield volcano?
What is lava?
200
What type of volcanic eruption is characterized by explosive eruptions ejecting a mixture of ash, lava fragments, and gases, often leading to the formation of steep-sided cone-shaped volcanoes?
What are cone volcanoes or stratovolcanoes?
200
What is the opening in a volcano through which lava, ash, and gases are ejected?
What is a Crater?
300
What geological process contributes to the formation of stratovolcanoes, involving the subduction of one tectonic plate beneath another?
What is the presence of convergent plate boundaries?
300
What volcanic hazard associated with cone volcanoes occurs when hot lava flows rapidly down the slopes, posing a threat to nearby communities and infrastructure?
What are lava flows?
300
What is the term for the volcanic gases emitted during eruptions from shield volcanoes, which can pose respiratory hazards?
What are volcanic emissions or volcanic gases?
300
What is the term for the volcanic gases emitted during eruptions from cone volcanoes, which can pose respiratory hazards and contribute to air pollution?
What are volcanic emissions or volcanic gases?
300
What is the term for a volcano that has not erupted in historical times but is still expected to erupt again in the future?
What is a Dormant volcano?
400
What geological process contributes to the formation of the alternating layers of lava flows, volcanic ash, and pyroclastic materials that characterize stratovolcanoes?
What is the repeated cycle of volcanic eruptions, including both effusive and explosive events?
400
What volcanic hazard is a common danger associated with the steep slopes of cone volcanoes and consists of rapidly moving flows of mud and debris?
What are lahars or volcanic mudflows?
400
What type of volcanic hazard is commonly associated with the collapse of the summit of shield volcanoes, leading to the formation of calderas?
What are summit collapses or caldera formation?
400
What unexpected danger associated with volcanic eruptions can affect global climate by releasing large quantities of sulfur dioxide and other gases into the atmosphere, leading to cooling effects on the Earth's surface?
What is the potential for "volcanic winter" or temporary global cooling?
400
The 1980 eruption of which volcano in the U.S. state of Washington caused the largest debris avalanche in recorded history and resulted in the deaths of 57 people?
What is Mount St. Helens?
500
What makes stratovolcanoes unique in terms of their eruptive behavior compared to other types of volcanoes?
What is their tendency to produce explosive eruptions due to the high viscosity of the magma and the buildup of gas pressure?
500
What term describes the rapidly flowing mixtures of hot gas, ash, and volcanic debris associated with explosive eruptions from cone volcanoes?
What are pyroclastic flows?
500
What is the term for the volcanic mudflows that can occur on the flanks of shield volcanoes due to the mixing of volcanic debris with water?
What are lahars?
500
What unexpected hazard can occur during volcanic eruptions when molten lava flows into the ocean, triggering explosions as the hot lava rapidly cools and solidifies, launching fragments of volcanic glass and rock into the air?
What are "lava entry hazards" or "lava ocean interactions"?
500
What is the term for the process by which magma from the Earth's mantle rises through the lithosphere and erupts onto the surface?
What is volcanic activity or volcanic eruption?
