What type of volcano causes landslides?
Landslides are common on volcanic cones because they are tall, steep, and weakened by the rise and eruption of molten rock. Magma releases volcanic gases that partially dissolve in groundwater, resulting in a hot acidic hydrothermal system that weakens rock by altering minerals to clay.
What type of volcano is likely to be the tallest and steepest?
Composite Volcano A composite volcano (cone-shaped volcano formed by alternating layers of solidified lava and rock particles) is a combination of a cinder cone and shield volcano that results from alternating eruptions of volcanic debris and lava. This type of volcano is likely to be the tallest and steepest volcano.
What type of volcanoes that produce the largest eruption?
Most shield volcanoes are formed from fluid, basaltic lava flows. Mauna Kea and Mauna Loa are shield volcanoes. They are the world's largest active volcanoes, rising over 9 km above the sea floor around the island of Hawai'i.
Is landslide associated with volcanic eruption?
Landslides can be caused by earthquakes or high rainfall, but volcanic activities such as magma intrusions and volcanic gas explosions can also be triggers. Large landslides caused by eruptions can create dams that block rivers and bury roads, bridges, and homes.
What causes of landslides?
Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
What are types of volcanoes?
The Three Classic Types of Volcanoes
- Cinder Cone Volcanoes.
- Composite Volcanoes (Stratovolcanoes)
- Shield Volcanoes.
Which type of volcano represents a typical volcano which can be described as a tall mountain?
stratovolcanoes Some of the Earth's grandest mountains are composite volcanoes–sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases.
What are the 3 types of volcanoes?
The Three Classic Types of Volcanoes
- Cinder Cone Volcanoes.
- Composite Volcanoes (Stratovolcanoes)
- Shield Volcanoes.
What type of volcano has the largest and most violent eruptions?
The largest and most violent of all the types of volcanic eruptions are Plinian eruptions. They are caused by the fragmentation of gassy magma, and are usually associated with very viscous magmas (dacite and rhyolite).
What is the most common cause of landslides?
Bottom line: Landslides are mainly caused by gravity acting on weakened rocks and soil that make up a sloping area of land. Both natural and human-related activities can increase the risk for landslides. Water from heavy rainfall is a frequent trigger for landslides.
Where is a landslide most likely to occur?
Landslides occur in every state and U.S. territory. The Appalachian Mountains, the Rocky Mountains and the Pacific Coastal Ranges and some parts of Alaska and Hawaii have severe landslide problems. Any area composed of very weak or fractured materials resting on a steep slope can and will likely experience landslides.
What are the 3 main types of volcanoes?
The Three Classic Types of Volcanoes
- Cinder Cone Volcanoes.
- Composite Volcanoes (Stratovolcanoes)
- Shield Volcanoes.
What are the 3 main types of volcanoes and their characteristics?
There are three main types of volcano – composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and (lava) flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
What is a stratovolcano volcano?
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra.
Which type of volcano represents a typical volcano which can be described as a tall mountain with a crater on top from which pyroclastic materials gases and lava escape?
stratovolcanoes Composite volcanoes. Some of the Earth's grandest mountains are composite volcanoes–sometimes called stratovolcanoes.
What are the 5 main types of volcanoes?
The five types of volcanoes we'll explore are:
- Cinder Cone Volcanoes.
- Complex Volcanoes.
- Composite/Strato-Volcanoes.
- Shield Volcanoes.
- Spatter Cone Volcanoes.

What are the 3 types of volcanoes describe the differences between each type?
Cinder cone volcanoes are relatively small, rarely exceeding 1,000 feet tall. Composite volcanoes, also known as stratovolcanoes, are towering structures, often rising more than 10,000 feet. Shield volcanoes are broad, typically 20 times wider than they are high. These volcanoes can be massive.
What type of volcano has the largest and most violent eruptions quizlet?
The largest and most violent of all the types of volcanic eruptions are Plinian eruptions. They are caused by the fragmentation of gassy magma, and are usually associated with very viscous magmas (dacite and rhyolite).
Where do most landslides occur?
Where do Landslides Occur? Landslides occur in every state and U.S. territory. The Appalachian Mountains, the Rocky Mountains and the Pacific Coastal Ranges and some parts of Alaska and Hawaii have severe landslide problems.
What factors cause landslides?
Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
What is the most common type of landslide?
A rotational slide with one or more curved slip sur- faces where the movement of material is incomplete, leaving individual slumped blocks, is referred to as a slump. Slides are probably the most common and overall possibly the most destructive type of landslide to hillside developments.
Can you drink lava?
Wax, kerosene, and polyethylene glycol are found, all dissolved in water. Wax is, in general, non-toxic in humans. Kerosene, at least in the amount that could be found in a lava lamp, is not poisonous, but the polyethylene glycol, could be a problem.
What is the difference between a stratovolcano and a shield volcano?
Composite volcanoes, also known as stratovolcanoes, are towering structures, often rising more than 10,000 feet. Shield volcanoes are broad, typically 20 times wider than they are high. These volcanoes can be massive.
Why are stratovolcanoes the most destructive?
Stratovolcanoes are the most dangerous volcanoes to humans and animals because they are very explosive, producing toxic gas and flying volcanic fragments. Explosive volcanic eruptions, which are common to stratovolcanoes, pose serious threats to aviation travel.
Why do composite volcanoes have the most violent eruptions?
Answer and Explanation: Composite cone volcanoes have the most violent eruptions because the magma being erupted is very viscous. This means it doesn't flow easily.
Which type of volcano represent a typical volcano which can be described as a tall mountain?
The most majestic of the volcanoes are composite volcanoes, also known as strato-volcanoes. Composite volcanoes are tall, symetrically shaped, with steep sides, sometimes rising 10,000 feet high. They are built of alternating layers of lava flows, volcanic ash, and cinders.
Which type of volcano represents a typical volcano which can be described as a tall mountain with a crater on top?
Cinder cones Cinder cones As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings.
What are the 4 main types of volcanoes?
Geologists usually group volcanoes into four main types: cinder cones, composite volcanoes, shield volcanoes, and lava domes.
Which type of magma is known for the most violent eruptions?
andesitic Explosive eruptions are favored by high gas content and high viscosity (andesitic to rhyolitic magmas).
