The stages of volcanism are:1. Pre-volcanic: This is the stage before the volcano starts to form.2. Volcanic: This is the stage where the volcano starts to erupt.3. Eruptive: This is the stage where the volcano starts to produce ash and gas.4. Explosive: This is the stage where the volcano starts to produce ash, gas, and lava.
How do volcanoes formed what are its two main processes?
Volcanoes form when molten rock called magma rises to the surface from the Earth’s mantle. The magma is made up of solid rock and gas. When the magma is thick, it can’t be released. The magma can form two main processes: magma streaming and magma chambers. Magma streaming means the magma is constantly moving up the Earth’s mantle. Magma chambers are where the magma is stored. When the magma is too thick, it can’t go into the magma streaming process.
Which word identifies one stage of volcanic activity Brainly?
Volcanoes are stages of volcanic activity.
What are the 4 steps of a volcano?
1. magma rises and cools2. ash and gas escape from the volcano3. ash falls from the volcano4. the volcano erupts
What are the types of volcanic activity?
Volcanoes are created when molten rock called magma rises to the surface from the Earth’s mantle. The magma is heated by the Earth’s core and melts. This liquid magma is then forced up the Earth’s mantle and into the crust. When it reaches the surface, the magma becomes solid and forms a volcano.
Which phrase describes a lava plateau?
A lava plateau is a plateau of molten rock that is located near the surface of a planet or moon.
What are the 4 types of volcanic eruption?
Volcanoes are formed when molten rock called magma rises to the surface from the Earth’s mantle. When the magma is thick, gas bubbles form and the pressure builds until the magma explodes from the volcano. There are 4 types of volcanic eruptions:1. Explosive: This type of eruption is when the magma explodes from the volcano, creating a huge fireball and ash cloud.2. Catastrophic: This type of eruption is when the volcano destroys everything in its path, including the village near the eruption site.3. Geothermal: This type of eruption happens when hot water and steam escape from the Earth’s surface.4. Volcanic: This type of eruption happens when the magma rises to the surface and explodes.
What are the 3 types of volcanoes?
A. Eruptions of molten rock and ash from the Earth’s surfaceB. The release of gas and ash from the Earth’s interiorC. The collapse of mountains, valleys, and other structures due to the force of the eruption
What are the four basic types of volcanoes and their characteristics?
Volcanoes are mountains with a hole in the middle that is filled with hot molten rock. They can erupt, and can produce ash, rocks, and gas.
How do the three types of volcano differ?
Volcanoes are formed when molten rock called magma rises to the surface from the Earth’s mantle. The magma is made up of many different elements and is heated by the Earth’s heat. When the magma is thick enough, it starts to form a volcano. The three types of volcano are:1. Vesuvius: This is the most famous volcano and is located in Italy. Vesuvius erupted in 79 AD and killed more than 79,000 people.2. Krakatoa: Krakatoa is the most active volcano and is located in Indonesia. Krakatoa erupted in 1883 and killed more than 19,000 people.3. Mount St. Helens: Mount St. Helens is the most active volcano in the US and is located in Washington. Mount St. Helens erupted in 1984 and killed more than 20,000 people.
Which phrase describe a volcano that is not expected to erupt again?
Volcanoes are not expected to erupt again for many years.
What are volcanoes and its types?
Volcanoes are mountains with magma ( molten rock) inside them. They can erupt, sometimes with a very large ash and ash plume, and can create a volcano field.
What are the 3 external parts of a volcano?
The 3 external parts of a volcano are the earth’s crust, the magma, and the ash.
What are the 7 parts of a volcano?
The seven parts of a volcano are the earth’s surface, the magma chamber, the vent, the ash cloud, the seismograph, and the geyser.
What are the 6 types of volcanic eruption?
There are six types of volcanic eruptions: ash, lava, earthquakes, tsunamis, volcanic ash clouds, and Vulcan’s eruptions.
What are the two classification of volcanoes?
Volcanoes are a type of mountain. They have a summit and a series of peaks that go up to it.
How are volcanoes distributed?
Volcanoes are distributed in a way that depends on the type of volcano. The most common type of volcano is a stratovolcano. Stratovolcanoes are made of a mixture of ash and rock that rise to the surface. They can be very destructive, and can cause extensive damage to communities near them.
What are the three stages of a volcano life?
The three stages of a volcano life are: pre-eruption, eruption, and post-eruption.
What are the 6 types of volcanoes?
A. Volcanoes are mountains that erupt, usually with ash and rock, and can be very dangerous.B. Volcanoes are mountains that are dormant, and when they erupt, they can create ash and rock that can be very dangerous.C. Volcanoes are mountains that are very active, and can create ash and rock that can be very dangerous.D. Volcanoes are mountains that are very small, and when they erupt, they can create ash and rock that is very dangerous.E. Volcanoes are mountains that are very old, and when they erupt, they can create ash and rock that is very dangerous.
What are the 3 main types of volcanoes and their characteristics?
Volcanoes are type of mountains that are formed when molten rock, ash, and gas escape from a volcano. The three main types of volcanoes are the Andes, the Himalayas, and the Hawaiian Islands. Each type of volcano has its own unique characteristics. The Andes are the tallest type of volcano and are located in South America. The Himalayas are the tallest type of volcano and are located in South Asia. The Hawaiian Islands are the smallest type of volcano and are located in the Pacific Ocean.
What are the parts of a volcano?
Volcanoes are made up of earth, ash, and gas. The ash is made up of small rocks that have been blasted into the air by the volcano. The gas is made up of hot gas and ash.
What are the 5 characteristics of a volcano?
Volcanoes are usually composed of molten rock and ash, with a high degree of gas and ash production. They are often located in areas with a large amount of seismic activity, which can cause them to erupt. Volcanoes are also known for their beautiful eruptive features, such as fumaroles and spouts.
What is the layers of ash and lava in a volcano?
The layers of ash and lava in a volcano are the different materials that are left after the volcano erupts. The ash is made up of small pieces of rock and ash, while the lava is made up of hot rock and ash.
What are the five major types of volcanoes?
A. Volcanoes are mountains that erupt.B. Volcanoes are mountains that form from magma.C. Volcanoes are mountains that are made from ash and ash products.D. Volcanoes are mountains that are made from ash and gas.
How many types of volcanoes are there?
There are three types of volcanoes: active, dormant, and extinct. Active volcanoes are the most active, while dormant volcanoes are the least active. Extinct volcanoes are the last to erupt, and are the most dangerous.
Where are volcanoes situated?
Volcanoes are situated in a variety of places around the world. They can be found in the Andes, the Himalayas, the Pacific Rim, and the Atlantic Isles.
Where are all active volcanoes?
There are over 100 active volcanoes in the world, and only a tiny fraction of them are located in the contiguous United States.
What events cause volcanic eruptions?
Volcanoes erupt when molten rock, ash, and gas escape from the Earth’s surface. These events can be caused by a variety of things, such as earthquakes, landslides, or volcanic eruptions.
