A combination of explosive and nonexplosive eruptions will create a diverse volcanic landscape characterized by various features. Explosive eruptions can form steep-sided stratovolcanoes with layers of ash and lava, while nonexplosive eruptions typically lead to the formation of broad shield volcanoes with gentle slopes. This interplay can result in complex volcanic structures, such as calderas, lava plateaus, and pyroclastic deposits, showcasing a range of volcanic activity and geology. Such environments often exhibit varied ecosystems and geological hazards.

A combination of explosive and nonexplosive euruptions will create a?
A combination of explosive and nonexplosive eruptions will create a complex volcanic landscape characterized by varied landforms and deposits. Explosive eruptions can produce ash clouds, tephra, and pyroclastic flows, while nonexplosive eruptions typically result in the formation of lava flows and shield volcanoes. This interplay can lead to diverse geological features, such as stratovolcanoes that exhibit layered deposits from both eruption types. The resulting environment can also influence local ecosystems and geological hazards.
2 types of volcanic eruptions?
Two types of volcanic eruptions are explosive eruptions, characterized by the violent ejection of lava, ash, and gases, and effusive eruptions, which involve the slow release of lava flows. Explosive eruptions are typically more destructive and can create volcanic ash clouds that pose hazards to aviation and human health. Effusive eruptions, on the other hand, can lead to the formation of lava plateaus and shield volcanoes.
Type of vesuvius eruptions?
Like many other stratovolcanoes, Mount Vesuvius varies in its type of eruptions. Some eruptions are explosive, producing clouds of ash. Others are are effusive, producing lava flows. The famous eruption that buried Pompeii in the year 79 was a highly explosive Plinian eruption.
What type of eruptions does Mount Veniaminof create?
Mount Veniaminof in Alaska is known for producing mainly effusive eruptions, where lava flows steadily out of the volcano and accumulates at the surface. These eruptions can be characterized by relatively low levels of explosivity. However, the volcano has also experienced occasional explosive eruptions in the past.
What are the differences of destruction done by effusive and explosive eruptions?
Effusive eruptions primarily produce lava flows that gradually spread out over the landscape, causing destruction mainly through the direct flow of molten rock, which can bury structures and alter terrain. In contrast, explosive eruptions release ash, gas, and pyroclastic materials violently into the atmosphere, resulting in widespread devastation due to ashfall, pyroclastic flows, and volcanic blasts. While effusive eruptions tend to create less immediate danger, explosive eruptions can lead to rapid and catastrophic impacts over large areas.

Why does granitic magma cause explosive eruptions?
Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.

Explain the lava flow that a nonexplosive eruption produces?
During a nonexplosive eruption, lava flows out from the volcano in a slow and steady manner. The lava is typically less viscous, allowing it to flow smoothly and cover greater distances. This type of eruption is characterized by the slow-moving streams of lava that can create new land formations as they cool and solidify.
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.
Which has a wider base volcano formed by a quiet or an explosive eruption?
A volcano formed by quiet eruptions typically has a wider base because the lava flows more easily and can spread out over a larger area. Explosive eruptions tend to create steeper-sided volcanoes with narrower bases due to the forceful ejection of volcanic material.
What pushed out of a volcano by the build up of gas?
Lava is pushed out of a volcano by the buildup of gas, primarily water vapor, carbon dioxide, and sulfur dioxide. As magma rises to the surface, the pressure decreases, allowing these gases to expand and create bubbles. This rapid expansion can lead to explosive eruptions, ejecting lava, ash, and volcanic gases into the atmosphere. The explosive force is often what characterizes certain types of volcanic eruptions, such as those from stratovolcanoes.
Why are some volcanoes more destructive then others?
Well, all volcanoes create land, but explosive volcanoes also destroy land. Explosive volcanoes are explosive because they have a lot of gas and pressure inside them, and then the pressure suddenly drops. That's when the volcano starts erupting.
