What volcanoes are formed by explosive eruptions that are followed by lava outpourings?
What else can I help you with?
Does a composite volcano have silica?
Yes it is high in silica because composite volcanoes are known for being explosive. Composite volcanoes, sometimes referred to as stratovolcanoes, one of Earth's most common type.They form by explosive eruptions of pyroclastic material followed by quieter outpourings of lava. This usually indicates high silica content. High silica makes for thicker magma that can clog up the vent from the volcanoe's last eruption. Which makes the next eruption far more explosive because the magma has to free its self out of the vent, and with tremendous force it succeeds sky rocketing billions of pieces of pyroclastic material out of its vent. (this is known as an explosive eruption.)
How do volcanoes differ?
Volcanoes differ in terms of their eruption style, which can vary from explosive eruptions with ash clouds and pyroclastic flows to effusive eruptions with lava flows. They also differ in shape and size, ranging from stratovolcanoes with steep slopes to shield volcanoes with gentle slopes. Additionally, the type of magma they erupt, such as basaltic, andesitic, or rhyolitic, can vary among volcanoes.
Name three types of volcano forms?
Shield volcanoes, stratovolcanoes, and cinder cone volcanoes are three types of volcano forms. Shield volcanoes have broad, gently sloping sides, stratovolcanoes are characterized by their steep-sided cones, and cinder cone volcanoes are made of pyroclastic fragments.
A composite volcano composed at alternating layers of lava and pyroclastic?
A composite volcano, also known as a stratovolcano, is characterized by its steep, conical shape and is formed from alternating layers of lava flows and pyroclastic materials, such as ash and volcanic rock. These layers result from varied eruptive activity, where explosive eruptions produce ash and debris, followed by quieter eruptions that emit lava. This combination leads to a more complex internal structure and a higher potential for explosive eruptions compared to shield volcanoes. Notable examples include Mount St. Helens and Mount Fuji.
When did mt kilauea start to erupt?
Kilauea's most recent eruption began on December 20, 2020. This eruption followed the volcano's previous activity in 2018 when it produced a series of lava flows and explosive eruptions.
What type of volcano has broad bases and summits with steep sides?
Cinder cone volcanos have steep sides and broadd bases.They are formed by explosive eruptions that are followed by lava outpourings.

are also known as Strato volcanoes. They are the most common type of volcano, and are formed by explosive eruptions of pyroclastic material followed by a quiet outpouring of lava.

Why did the volcano outside of Pompeii erupt?
Mount Vesuvius erupted in 79 A.D. because this is what active volcanoes do. They continually smoulder and produce eruptions every few thousand years. Scientific research has shown that Mt Vesuvius was formed 25,000 years ago and was built up by a series of small lava flows and by some eruptions. Around 19,000 years ago, there was the beginning of large explosive eruptions (eruptions which involve explosions which throw volcanic ash in the air). A large explosive eruption which occurred 18,000 years ago created the mountain's current caldera (the cauldron-like feature at the top). This was followed by a series of non-explosive, but lava-producing eruptions. There was a large explosive eruption 11,000 years ago and three small explosive eruption 8,000 and 5,000 years ago and 3,800 years ago there was a large one. The explosion which buried Pompeii and Herculaneum in 79 A.D. was the last large explosive eruption of Mt Vesuvius. There will be further explosive eruptions in the distant future.

How many years between every volcano eruption from 1 volcano?
It varies widely. Some volcanoes will erupt every few years or even every few months while others can go hundreds of years without an eruption. Even for one volcano activity is not regular. Major eruptions are often preceded and followed by a series of small eruptions.
What gas do volcanoes initially put into the atmosphere in the greatest amount?
Volcanoes initially release water vapor (H2O) in the greatest amount during eruptions. This is followed by significant emissions of carbon dioxide (CO2) and sulfur dioxide (SO2). The exact composition can vary depending on the type of volcano and the magma involved, but water vapor is typically the predominant gas emitted.
What is the eruption cycle of popocatepetl?
Popocatépetl, an active stratovolcano in Mexico, has a history of periodic eruptions. Its eruption cycle can vary significantly, with phases of dormancy followed by explosive activity. The most recent eruptive period began in 1994, marked by frequent eruptions of varying intensity, including ash emissions and occasional lava flows. The volcano remains closely monitored due to its potential hazards to nearby populations.
Can a volcano break?
It depends on what you mean by "break." Many volcanoes are prone to landslides, some of which can be quite large. The largest landslide on record occurred when the entire northern face of Mount St. Helens gave way. It was immediately followed by a catastrophic eruption. Extremely large eruptions can cause a volcano to collapse in on itself, leaving a massive depression called a caldera.
