What determines the frequency and types of eruptions you can expect from a volcano?

The crystal and gas content and temperature of a magma help determine a volcano's eruption style.
• Crystals in magma make it more viscous, so magma with a high crystal content is more likely to explode than flow.
• Gases create explosions if they cannot easily escape from viscous magma, but they can also be released without explosions (or with only minor ones) from fluid magma.
• High-temperature magmas usually erupt effusively, while low-temperature magmas cannot flow easily and are more likely to erupt explosively.

The frequency and types of eruptions from a volcano are mainly determined by the composition of the magma, the presence of gas content, and the tectonic setting of the volcano. Magma with high silica content tends to erupt explosively, while low silica magma often erupts effusively. The amount of gas dissolved in the magma can also influence eruption styles. Additionally, the interaction of magma with water or other external factors can trigger different types of eruptions.

What kind of eruption quiet explosive or both at different times would you expect to come from a cinder cone volcano composite volcano and a shield volcano?
A cinder cone volcano typically has quiet eruptions, characterized by the ejection of small fragments of lava and ash. Composite volcanoes can have both quiet and explosive eruptions, due to the buildup of pressure from the highly viscous magma. Shield volcanoes generally have non-explosive eruptions, with flowing lava that travels long distances.
What kind of volcanic activity might you expect to observe near a dormant volcano?
Near a dormant volcano, you may still observe geothermal activity such as hot springs and fumaroles due to underground magma or hot fluids. There might be some minor seismic activity as well. However, there would be no active lava flows, ash eruptions, or significant eruptions occurring near a dormant volcano.
What geologic features would you expect to find on the ocean floor near the volcano and earthquake areas on your map?
Near volcano and earthquake areas on the ocean floor, you would expect to find features like mid-ocean ridges, deep-sea trenches, seamounts, and hydrothermal vents. These features are associated with tectonic plate boundaries and geological activity, such as volcanic eruptions and seismic events, that occur in these areas.
What type of rocks would you expect to find around a volcano crater?
You would find extrusive igneous rocks. Beyond that it depends on the volcano.
What are rifts and what kinds of eruptions would you expect?
Rifts are linear zones where Earth's lithosphere is being pulled apart, leading to the formation of new crust. Eruptions within rift zones are typically characterized by effusive lava flows, shield volcanoes, and occasional explosive eruptions. These eruptions are generally less violent compared to those at subduction zones due to the lower silica content in the magma.

What is a volcano that is sleeping but scientists expect to erupted in the the near future?
Dormant volcano
What kind of eruptions would you expect in rifts?
Complex Eruption???

Where would you expect to find lava solidifying into basalt?
You would expect to find lava solidifying into basalt at the surface of a volcano or lava flow. Basalt is a common volcanic rock that forms when lava cools and solidifies quickly, usually in areas with high volcanic activity.
Do scientists expect mount pelee to erupt again?
Yes, scientists consider Mount Pelée to be an active volcano with a history of periodic eruptions. While it is impossible to predict exactly when it may erupt again, monitoring systems are in place to detect any signs of impending activity. Environmental and hazard assessments are also conducted regularly to ensure preparedness for potential eruptions.
What should you expect to see during an nonexplosive eruption?
During a nonexplosive eruption, you can expect to see a steady flow of lava mainly from fissures or vents on the volcano. This type of eruption typically causes slow-moving lava flows, rather than dramatic explosions. Ash and gas emissions may still occur but are usually not as intense as in explosive eruptions.
